记者从中科院华南植物园获悉,该园科学家近日成功揭示了种子成熟过程的表观遗传调控机制。业内专家认为,该研究对通过表观遗传调控改善作物性状、提高作物产量、解决我国粮食安全问题具有重要理论意义。相关研究成果日前在线发表于《植物细胞》。据介绍,植物种子成熟期是种子发育的一个关键时期,在此阶段,种子完成淀粉、脂类、蛋白质等贮藏物的合成积累。其中,种子贮藏蛋白的合成与积累是种子成熟过程中的一个重要方面。研究表明,种子贮藏蛋白基因的表达受许多不同的调控因子影响。然而,学界关于它们的 Reporter learned from the South China Botanical Garden, Chinese Academy of Sciences, the park scientists recently successfully revealed the epigenetic regulation of seed maturation mechanism. Industry experts believe that this study is of great theoretical significance for improving crop traits, increasing crop yields and solving the problem of food security in China through epigenetic regulation. Relevant research results published online in the “Plant Cell.” According to reports, the maturity of plant seeds is a critical period of seed development, at this stage, the completion of the synthesis of starch, lipids, proteins and other storage accumulation. Among them, the synthesis and accumulation of seed storage protein is an important aspect of seed maturation process. Studies have shown that the expression of seed storage protein genes is affected by many different regulatory factors. However, academics about them
