磷酸烯醇式丙酮酸羧化酶(PEPC)是C4光合关键酶, 有助于植物在非生物胁迫下抵御逆境。异子蓬(Suaeda aralocaspica)是一种无须Kranz结构即可在单细胞中高效执行C4光合作用的荒漠盐生植物, 在C3作物遗传改良方面具有天然优势。以转异子蓬SaPEPC2基因烟草(Nicotiana tabacum)为材料, 探讨了其抗旱功能和光合性能。结果表明, 过表达SaPEPC2提高了烟草叶片持水能力, 可保持叶绿素稳定; 积累更多的渗透调节物质, 增强了抗氧化酶活性, 进而降低了植株体内的活性氧水平, 减轻膜损伤程度; 同时还增强了烟草抗旱相关基因和内源光合基因的表达, 提高了PEPC活性和净光合速率, 可能是促进了烟草体内的“类C4微循环”途径所致。研究结果为进一步利用异子蓬单细胞C4途径PEPC基因培育高光效抗逆农作物品种奠定了基础。

INTRODUCTION: Phosphoenolpyruvate carboxylase (PEPC) is a key enzyme for C4 photosynthesis that help plants to resist adversity under abiotic stress. Suaeda aralocaspica, an annual halophyte, has gradually developed a single-cell C4 photosynthetic pathway by compartmentalizing a chlorenchyma cell into distal and proximal ends to delineate and form the four-carbon (C4) and three-carbon (C3) cycles through long term of evolution. This unique biochemical compartmentation pattern holds promise for introducing “C4-like microcirculation” into C3 plants without establishing Kranz anatomy.
RATIONALE: The PEPC gene act as an essential component of C4 photosynthesis, but few studies have reported on the PEPC gene in single cell C4-pathway species. To reveal the impact of the SaPEPC2 gene from S. aralocaspica on the photosynthetic performance and drought resistance of C3 plants, we evaluated the drought resistance function and photosynthetic performance of transgenic tobacco (Nicotiana tabacum) overexpressing the SaPEPC2 gene driven by its own promoter (ProSaPEPC2::SaPEPC2) through physiological measurements and gene expression analysis methods.
RESULTS: Our findings demonstrated that overexpressing the SaPEPC2 gene in tobacco improved leaf water retention, maintained chlorophyll stability, promoted the accumulation of osmotic adjustment substance, enhanced antioxidant enzyme activities, reduced ROS levels, mitigated the extent of membrane damage, upregulated the expression of drought-related and endogenous photosynthesis genes, and increased PEPC enzyme activity and net photosynthetic rate.
Overexpression of SaPEPC2 in tobacco results in stronger drought resistance and higher photosynthesis efficiency compared to non-transgenic plants.
