Abstract

Photosynthesis, which is the foundation of crop growth and development, is accompanied by complex transcriptional regulatory mechanisms. Research has established that brassinosteroids (BRs) play a role in regulating plant photosynthesis, with the majority of research focusing on the physiological level and regulation of rate-limiting enzymes in the dark reactions of photosynthesis. However, studies on their effects on maize photosynthesis, specifically on light-harvesting antenna proteins, have yet to be conducted. The peripheral light-harvesting antenna protein is crucial for capturing and dissipating light energy. Herein, by analyzing the transcriptomic data of maize seedling leaves treated with 24-epibrassinolide (EBR) and verifying them using qPCR experiments, we found that the MYBR17 transcription factor may regulate the expression of the photosynthetic light-harvesting antenna protein gene. Further experiments using protoplast transient expression and yeast one-hybrid tests showed that the maize transcription factor MYBR17 responds to EBR signals and binds to the promoter of the light-harvesting antenna protein , thereby upregulating its expression. These results were validated using an Arabidopsis mutant. Our results offer a theoretical foundation for the application of BRs to enhance the photosynthetic efficiency of maize.

摘要

光合作用是作物生长发育的基础，伴随着复杂的转录调控机制。研究表明，油菜素内酯（BRs）在调节植物光合作用中发挥作用，大多数研究集中在生理水平以及光合作用暗反应中限速酶的调控上。然而，关于它们对玉米光合作用的影响，特别是对光捕获天线蛋白的影响，尚未开展相关研究。外周光捕获天线蛋白对于捕获和消散光能至关重要。在此，通过分析用24-表油菜素内酯（EBR）处理的玉米幼苗叶片的转录组数据，并使用qPCR实验进行验证，我们发现MYBR17转录因子可能调控光合光捕获天线蛋白基因的表达。利用原生质体瞬时表达和酵母单杂交试验进行的进一步实验表明，玉米转录因子MYBR17对EBR信号作出反应，并与光捕获天线蛋白的启动子结合，从而上调其表达。使用拟南芥突变体对这些结果进行了验证。我们的结果为应用BRs提高玉米光合效率提供了理论基础。
