　　GBSS1 (Granule-bound starch synthase1) controls amylose synthesis in all cereals.Previous reports on its regulation have been primarily focused on its transcriptional and post-transcriptional levels.In this study, we established that GBSS1 from Oryza sativa L.(OsGBSS1) is capable of forming oligomers in the rice endosperm and the polymerized OsGBSS1 exhibits much higher enzymatic activity.

高温强光下Ca2+对花生光系统的保护作用
高温强光胁迫是影响我国花生产量的主要因素之一，高温强光下花生吸收的光能来不及耗散，由光激发产生的多余电子就会通过Mehler反应传到02产生活性氧在光合器官积累，而活性氧积累很容易对光系统造成伤害。有研究表明钙离子可以缓解环境胁迫对植物的伤害。
