Protein-protein interactions play a key role in cellular signaling, involved in various biological processes. Studies on these interactions are therefore crucial toward understanding the regulatory networks of cellular signaling. It is a standard practice that the protein-protein interactions identified by the yeast two-hybrid system should be independently confirmed by in vitro and in vivo approaches. Pull-down and co-immunoprecipitation (Co-IP) are routine approaches to detect protein-protein interactions. Pull-down assay is used to detect direct or physical interactions between proteins in vitro. In plant biology studies, one of the most convenient methods to detect protein-protein interactions is the transient expression of the target proteins in Nicotiana benthamiana leaves followed by the Co-IP assay. In this paper, we describe the principles and protocols for the GST tag-based pull-down assay and the Co-IP assay of proteins transiently expressed in N. benthamiana leaves, providing a reference for detecting plant protein-protein interactions.

Tea (Camellia sinensis) is one of the most important beverage crops in the world. With the expanding cultivation area, the demand for tea seedlings is increasing. However, there are many problems with the traditional breeding method for tea plants using cuttings, such as low rooting rate, time consumption and difficulties to obtain materials. Therefore, optimizing the cutting method is of great importance for tea production. In this study, we first changed the culture medium to sponges and found that tea cuttings were able to generate new roots within 1 month on sponges, with rooting rate 32.2%. Second, we optimized the cutting materials by using fresh green tea branches in sponges, and the rooting potential of goung branch maintained with one bud and one leaf is better. In addition, we found that supplying rooting powder to sponges significantly promoted callus formation and new root generation from cuttings. In general, the most effective way was to apply 1.25 g∙L -1 rooting powder to cuttings for 48 h, for a rooting rate of 42.0%. We have established an effective rooting method for tea cuttings by optimizing the culture medium, cutting materials and adding optimal rooting powder. This method could shorten the rooting time, avoid the restriction of cutting materials, and thus effectively reduce the expense of tea cuttings, which has application prospects in tea production.

Ubiquitin activating enzyme (E1), ubiquitin conjugating enzyme (E2) and ubiquitin protein ligase (E3) are the key enzymes of ubiquitin modification of substrate proteins. There are large amounts of genes encoding these ubiquitination enzymes in all eukaryotic genomes. Analyzing the biochemical characteristics and specificity of these enzymes and their substrate proteins is important for their functional study. Here we describe a simple and fast method for in vitro ubiquitination assay. In the presence of E1 and ubiquitin, E2 activity can be determined by detecting the DTT-sensitive thio-ester formation. The E3 activity of a putative protein as well as the E2-E3 or E3-substrate specificities can also be explored by in vitro ubiquitination assay. This system is mainiy based on proteins from Arabidopsis, which includes most varieties of Arabidopsis E2 proteins that are tested with several RING-finger type E3 ligases. This system facilitate not only the exploration of E3 activity in combination with various Arabidopsis E2 members but also the study of E2-RING E3 and RING E3-substrate specificities. This system is suitable for the ubiquitination assays of eukaryotic proteins, especially for plant proteins.

Protein phosphorylation is one of the important protein posttranslational modifications that is involved in the regulation of most cellular processes in plants. Protein kinases catalyze the phosphorylation by transferring the phosphate group in ATP to the substrate proteins. The phosphate is usually covalently linked to the hydroxyl group of specific amino acid residues in the substrates by an ester bond. The mostly studied phosphorylation sites are serine, threonine, and tyrosine residues. Here, we present protocols and related tips for the in vitro and in vivo protein phosphorylation assays.

Sporangia are propagative organs of ferns and their morphology has great significance for fern taxonomy and phylogeny. In this study, we used sodium hypochlorite solution to observe fern sporangia. By this process, we could obtain sporangia photos under light microscopy. We studied the sporangia morphology of 13 species belonging to four genera of the fern family Lindsaeaceae and found that the shape of the capsule is ellipsoidal, with a vertical annulus; the pedicel is composed of three rows of cells. The cell number annulus is reduced in Odontosoria, Osmolindsaea, Tapeinidium and Lindsaea, whereas the volume of capsule and cell number of stomium and capsule are reduced in Odontosoria, Tapeinidium, Osmolindsaea and Lindsaea. As well, the same genus shows more differences between species, such as Odontosoria biflora and O. chinensis as well as Osmolindsaea odorata and Os. japonica, but less difference between the genera of Tapeinidium and Lindsaea. Studies of sporangia morphology will be useful for further research in other groups of ferns.

It is very important but usually difficult to extract high quality DNA from plants for molecular work since there exist a great deal of polysaccharides, hydroxybenzenes, esters and other secondary metabolities. In this paper we provide a simple modified CTAB (mCTAB) protocol for extracting plant DNA. The mCTAB method protocol includes 18 steps. (1) Weigh ca. 20 mg of dry plant tissue and ground into powder with sand using a mortar or a pestle. Remove the powder into a 2.0 mL microcentrifuge tube. (2) Add 1.0 mL pre-cooled buffer A (Table 2) to the tube, mix well and incubate the tube on ice for 15 min. Mix sample 2–3 times during incubation by inverting the tube. (3) Centrifuge the tube at 7 000 ×g for 10 min. Discard the supernatant liquid by pouring it out of the tube. (4) Repeat step 2 and 3 until the supernatant is not viscous. (5) Add 0.7 mL buffer B (Table 3), mix well and incubate at 65°C for 90–120 min. Mix the sample several times during incubation by inverting the tube. (6) Centrifuge at 10 000 ×g for 10 min, remove the supernatant to a new microcentrifuge tube. The precipitate is reusable from step 5 if necessary. (7) Add 0.7 mL CI (chloroform: isoamyl alcohol=24:1, v/v), mix it well for 10 min by inverting tube gently. (8) Centrifuge at 10 000 ×g, for 10 min, carefully remove the supernatant to a new 1.5 mL microcentrifuge tube. (9) Repeat step 7 and 8 until no precipitate appearing between the two layers of liquid after centrifuging. (10) Add 0.5 mL pre-cooled isopropanol, carefully mix well . Incubate at –20°C for 20 min. (11) Centrifuge at 10 000 ×g for 10 min, discard the supernatant, centrifuge the tube briefly to collect the remaining liquid and remove it by pipetting. (12) Add 0.1 mL RNase (100 mg·L–1) and incubate at 37°C for 30–60 min. (13) Add 0.1 mL ddH2O, 0.1 mL 5 mol·L–1NaCl and 0.8 mL pre-cooled ethanol (95%), carefully mix well. (14) Centrifuge at 10 000 ×g for 10 min, discard the supernatant. (15) Add 0.5 mL 75% ethanol, re-suspend the pellet, centrifuge at 10 000 ×g for 2 min, discard the supernatant. (16) Repeat step 15. (17) Add 0.1 mL TE to dissolve DNA after ethanol has evaporated. (18) Estimate the concentration and the purity of the DNA solution. Store it at 4°C for immediate use, at –20°C for short time storage and –80°C for long time storage. We compared our protocol with four frequently used and commercially available kits. The result showed that our mCTAB method yielded much more DNA of high quality that is suitable for PCR amplification but with much lower cost.

Post-translational modification by small ubiquitin-related modifiers (SUMOs) is an important regulatory process to modulate protein function. This paper summarizes the SUMOylation pathway in plants; the pathway consists of SUMO molecules, a SUMO conjugation enzyme cascade and de-conjugation enzymes. Nascent SUMOs are processed by SUMO-specific proteases, then mature SUMOs are conjugated to substrate proteins by sequential action of three groups of enzymes: SUMO-activating enzymes (E1), SUMO-conjugating enzymes (E2) and SUMO-ligating enzymes (E3). SUMOylation can be reversed by SUMO-specific proteases. SUMO modification in plants is involved in flowering induction, hormone signaling, pathogen defense and stress response.

Genome-wide association study (GWAS) is a general approach for unraveling genetic variations associated with complex traits in both animals and plants. The development of high-throughput genotyping has greatly boosted the development and application of GWAS. GWAS is not only used to identify genes/loci contributing to specific traits from diversenatural populations with high-resolution genome-wide markers, it also systematically reveals the genetic architecture underlying complex traits. During recent years, GWAS has successfully detected a large number of QTLs and candidate genes associated with various traits in plants including Arabidopsis, rice, wheat, soybean and maize. All these findings provided candidate genes controlling the traits and theoretical basis for breeding of high-yield and high-quality varieties. Here we review the methods, the factors affecting the power, and a data analysis pipeline of GWAS to provide reference for relevant research.

TDZ(N-phenyl-N’-1,2,3-thidiazol-5-yl-urea) is a substituted phenylurea compound and has emerged as a highly efficacious bioregulant of morphogenesis in the tissue culture of many plant species. Application of TDZ induces a diverse array of cultural responses ranging from induction of callus to formation of somatic embryos.TDZ exhibits the unique property of mimicking both auxin and cytokinin effects on growth and differentiation of cultured explants. The recent app roaches applied to study the morphogenic events initiated by TDZ are clearly beginning to reveal the details of a variety of underlying mechanisms. Various reports indicate that TDZ may act through modulation of the endogenous plant growth substances, or as a result of induced stress. The other possibilities include the modification in cell membranes, energy levels, nutrient uptake, or nutrient assimilation. In this review, several of these possibilities are presented and summarized in light of recently published studies on characterization of TDZ-induce dmorphogenic effects.

All organism respond to elevated temperatures and many other stresses with the production of a defined set of proteins called heat shock proteins ( HSPs). The basic characteristics of HSPs are highly conserved, diversed and the heat shock response is temporal. Although HSPs were first characterized because their expression increased in response to elevated temperature, some HSPs are found at sighificant levels in other stresses, in normal, nonstressed cells and produced at particular stages of cell cycle or during development in the absence of stresses. The findings indicated that HSPs have many functions, including molecular chaperones, thermotolerance, chilling tolerance, a special role in the development of organisms and other biochemical functions in cell metabolism, The association of HSF with HSP70 may be important in the regulation of heat shock gene transcriptional activity. The expression of heat shock gene is self-regulated by HSP.

Retrotransposons are a class of eukaryotic transposable elements, consisting of the long terminal repeat (LTR) and non-LTR retrotransposons. Retrotransposons are ubiquitous in the plant kingdom by high copy number and can be transmitted between generations by vertical transmission and between species by horizontal transmission. The same family retrotransposons presented highly heterogeneous populations in all higher plant genomes. Many of the plant retrotransposons are transcriptionally activated by various biotic and abiotic stress factors. Retrotransposons are used as molecular markers for their traits. S-SAP, IRAP, REMAP and RBIP are developed and will be applied widely in gene mapping, genetic biodiversity and phylogeny studies, and cultivar certification.

Light is an important environmental factor that affects plant growth and development. Flowering is the most important event in higher plants. Plants perceive accurately changes in the surrounding light environments by photoreceptors, thus activating a series of signaling transduction processes and initiating flowering. Here, we summarized the current understanding of the structural characteristics and physiological functions of various photoreceptors in higher plants. We reviewed the molecular mechanisms of phytochromes, cryptochromes, and FKF1/ZTL/LKP2 in mediating signaling transduction and flowering time, including transcriptional and post-transcriptional regulation of CO and FT. Finally, we described the advances in photoreceptor-mediated-integration of light, temperature, and gibberellin signals in regulating flowering. Future directions in this area were also proposed.

Abstract2595)            Save
Glutamate dehydrogenase(GDH) is present mainly in mitochondria in higher plants and catalyses both the amination of a-oxoglutamate, with NADH as the electron donor, and the deamination of glutamate to ammonia and a-oxoglutamate, with NAD+ as the electron receptor. The NAD (H)-GDH, with a molecular weight of 255-258kD, is composed of six subunits of a and b in different ratios to form seven isoenzymes. The enzyme seems to function in assimilation of ammonia under stress conditions such as high temperature, in senescence and other abnormalities. It also functions in higher plants to direct carbon skeletons into the citric acid cycle under conditions of carbon stress.

Abscisic acid (ABA) plays a key role in the growth, development and stress condition of plants. The process of plant response to ABA is completed by signal recognition, transduction, and response cascades. The core ABA signaling pathway consists of receptor RCAR/PYR/PYLs, phosphatase PP2Cs, kinase SnRK2s, and transcription factors and ion channel proteins.

Anthocyanins are among the most important flavonoid compounds widely present in plants. Anthocyanins play significant roles in plant growth and development as well as human nutrition and health care. The anthocyanin biosynthetic pathway has been widely documented, and the anthocyanin metabolic regulation network is being constantly improved. The transcription factors that regulate anthocyanin biosynthesis mainly include three classes: MYB, bHLH and WD40 proteins. The proteins regulate the accumulation, location and levels of anthocyanins by activating or suppressing the expression of key structural genes, including CHS, ANS and DFR. This review briefly introduces the anthocyanin biosynthetic pathway and summarizes the molecular mechanism of transcriptional regulation based on recent progress. It mainly focuses on the molecular mechanism of MYB, bHLH and WD40 transcription factors in the regulation of anthocyanins in model plants. In addition, it summarizes the use of these transcription factors in anthocyanin metabolic engineering in ornamental plants and fruit crops. This review will provide valuable references for the in-depth investigation of transcriptional regulation and improving anthocyanins by metabolic engineering.

The GRAS family is a class of plant specific transcription factors, playing essential roles in plant development and light signal transduction pathways. 33 GRAS family genes were identified in Arabidopsis genome. In this study, we found a group of GRAS family genes in response to osmotic and/or drought stresses through Arabidopsis GeneChip data mining. Meanwhile, we conducted co-expression analysis and gene ontology (GO) analysis and predicted that SCL13 was possibly involved in the response to osmotic stress. Our study will be helpful to elucidate some GRAS family genes related in signal transduction pathways during water stress, and be beneficial to crop molecular breeding in the future.

Sphingolipids are ubiquitous membrane components in eukaryotic cells and in a few bacteria. Recent information indicated that sphingolipids are an impor tant class of messenger molecules involved in many significant signal trans duction pathways, regulating cell growth, differentiation, senescence, and apoptosis in mammals and yeast. However, the biological function of sphingolipids in plants has been explored only recently and remains elusive. Increasing investigation has shown that sphingolipids and their metabolites play an important role in plants. In this review, we describe the structure, metabolic pathway and biological function of sphingolipids.

Abscisic acid (ABA) participates in the control of diverse physioogical process. Although the molecular mechanism of ABA action is unknown, ABA receptor(s) have not yet been identified, high affinity of ABA binding proteins in some plants, either membrane-bound or soluble, have been described. The sense of ABA lies in the outside or inside of plasma membrane, there are some evidences with the techniques of microinjeetion. Considerable progress has been recently made in the characterization of more downstream elements of the ABA regulatory network, especially in the control of stomatal aperture by ABA. The details of the underlying signalling pathways start to emerge.
