研究领域

植物高光效与抗逆性机理 1. 植物高光效机理及其利用:采用多基因转化技术分流光呼吸乙醇酸代谢,构建C3植物光合CO2浓缩机制,旨在提高作物光合效率、产量及其抗逆性。 2. 植物活性氧信号发生与抗逆性:植物体内H2O2总量的70%来源于光呼吸代谢,当植物处于干旱、高温等逆境时这一比例会更高。我们的研究表明,光呼吸关键酶GLO与CAT的互作/解离可作为产生H2O2波的调控开关,是一种新的H2O2信号发生机制。将致力于深入解析这种新开关机制的调控分子机理及其生物学功能。 3. 植物草酸代谢调控机理:草酸在植物抗重金属毒害、耐低磷、提高N素利用效率等过程中起重要作用,但过量存在于食品中却对人体有害,因此阐明植物草酸代谢及其调控机理是合理有效利用草酸功能的关键。本课题组在该领域已有三十多年的研究积累,目前正致力于草酸合成的亚细胞定位及其代谢关键基因克隆与功能分析。 上述研究旨在最终获得高光效及高抗(如抗旱,抗高温高光、抗重金属)作物新材料,为作物分子改良育种提供指导。
