水稻种子内生细菌研究进展

doi:10.13560/j.cnki.biotech.bull.1985.2021-0437

摘要/Abstract

摘要：

水稻的根、茎、叶、种子等器官存在大量对植株生长和产量、品质、抗性等有重要作用的共生和伴生微生物,其中内生菌是种子共生和伴生微生物中的一个代表类群。水稻种子中普遍存在种类丰富且结构复杂的内生菌群落,会直接或间接地影响种子的萌发、生长和群体的产量特性。从水稻种子内生细菌的多样性、水稻种子与其内生细菌分布的相关性、水稻种子内生菌的生物学功能及水稻种子内生菌的垂直传递4个方面对目前有关于水稻种子内生菌的研究进行了综述,以期为后续相关水稻种子内生菌的研究提供参考。在此基础上,对水稻内生菌研究的短板——“杂交水稻种子内生菌”研究做出论述与展望,希望能够引发读者思考。

Abstract:

There are a large number of symbiotic and associated microorganisms in roots,stems,leaves,seeds and other organs of rice,which play an important role in plant growth,yield,quality and resistance,among which endophyte is a representative group of seed symbiosis and associated microorganisms. Endophytic communities with rich species and complex structure are common in rice seeds,which will directly or indirectly affect seed germination,growth and population yield characteristics. To provide a reference for the follow-up study of endophytic bacteria in rice seeds,this study reviewed the current studies on endophytic bacteria in rice seeds from four aspects：The diversity of endophytic bacteria in rice seeds,the correlation between rice seeds and the distribution of endophytic bacteria,the biological function of endophytic bacteria in rice seeds,and the vertical transmission of endophytic bacteria in rice seeds. On this basis,this paper discussed and prospected the research on endophytic bacteria in hybrid rice seeds,that is the deficiency of the research on endophytic bacteria in rice seeds,aiming to trigger readers’ thinking.

Key words: endophytic bacteria, rice seed, diversity, biological function, vertical transmission, hybrid rice
