| 中文摘要: |
| 种子大小是影响作物产量的关键因素，并且在植物进化适应过程中也起到至关重要的作用。植物种子包括胚、胚乳和种皮3种具有不同遗传特性的结构。因此，种子的大小是由胚、胚乳和母本组织的生长共同协调决定的。近年来研究发现拟南芥和水稻等模式植物中的泛素途径相关因子也参与种子大小的调控。泛素途径对种子大小调控的研究为深入了解植物种子大小调控机理提供重要思路，也将为作物高产育种提供理论基础。 |
| 英文摘要: |
| Seed size is a key factor for crop yield,and is also crucial for plant evolution.Plant seed size is composed of three parts such as the embryo,the endosperm and seed coat,all of which is different genetic background.Therefore,in higher plants,the seed size is controlled by the growth of the above three compositions.Recent studies find that some factors involved in ubiquitin/26S proteasome system (UPS) can determine the seed size in Arabidopsis,rice (Oryza sativa) and some other plants.The study of UPS in seed size regulation offers insights into the mechanism of seed size control in plants.In addition,it will provide a theoretical basis for high yield breeding of crops. |
