Figure 1. Research themes of Chinese scientists published in major journals of plant sciences (Molecular Plant, The Plant Cell, Plant Physiology and The Plant Journal) from 2016 to 2018 (data sources: Web of Science; data collected by July 2, 2019)
Keyword co-occurence cluster of papers published by Chinese scientists in four plant science journals from 2016 to 2018 was constructed by VOSviewer. (A) The themes of 2016: Arabidopsis protein kinases and plasma membrane-dependent endocytosis under salt stress (blue); differentially expressed genes in rice and coding genes prediction (maize and barley), genome colinea- rity and DNA methylation and demethylation (red); Pseudomonas syringae induced cell death and systemic acquired resistance and immunity (orange); key enzymes of metabolism (such as alternative oxidase and synthase complexes), roles of NO in oxidative stress, cyclic electron flow of PSII and pentatricopeptide repeat (PPR) (green); transcription factors, circadian clock and root development (yellow-green); flower development and floral organ identity and signaling pathways (light pink). (B) The themes of 2017: plant innate immunity, immunity activation, disease resistance and defense mechanism (blue); chlorophyll fluorescence of PSI and PSII, mitochondria and chloroplast gene family and related mutants (red); rice genome, metabolism and natural variation, RNA-seq, evolution and DNA methylation (green); salt stress of Arabidopsis (yellow-green); plant growth and development and water use efficiency (light pink). (C) The themes of 2018: Pseudomonas syringae induced cell death, disease resistance recognition and gene family response on stress (blue); evolution and domestication of polyploid species, flowering time and natural variation of rice, genome (maize, barley, etc.), genetic diversity of wheat (Aegilops tauschii), and collinear analysis (red); thylakoid membrane protein of PSI and PSII; phosphorylation in vivo, homologous recombination and triacylglycerol accumulation (green); plant growth and development and negative regulators; biosynthesis of chlorophyll and hormone (auxin and abscisic acid) proteins (purple); Arabidopsis plasma membrane proteins and cell tissue dynamics (yellow green).
