摘要:

马铃薯(Solanum tuberosum L.)块茎诱导和形成是其生长发育和产量决定最重要的事件,涉及多重环境因素与植物激素及信号分子的互作以及这种互作对大量关键基因及多条信号转导与代谢途径的调控。概述了马铃薯块茎形成的生理生化基础,包括块茎形成的过程及影响块茎形成的内源因素和环境条件;讨论了块茎诱导形成过程中信号转导途径及相关基因、蛋白、miRNAs、激素和第二信使分子等对块茎形成的调节;构建了块茎诱导形成过程中可能的分子互作网络;展望了未来研究的方向和可能的突破点,旨在为将来通过精准分子育种手段来培育高产优质的马铃薯品种提供借鉴和新思路。

Abstract:

Tuber induction and formation of potato(Solanum tuberosum L.)is the most pivotal event in their growth,development and determination of yield,which involves the interaction of multiple environmental factors with plant hormones and signal molecules,as well as the regulations of this interaction on large number of key genes and multiple signal transduction and metabolic pathways. This paper overviewed the physiological and biochemical basis of potato tuberization,including the process of tuberization and the endogenous factors and environmental conditions affecting the tuberization. Also the paper discussed the signal transduction pathways and regulatory roles of related genes,proteins,miRNAs,hormones and second messenger molecules in tuberization. Further a possible network of molecular interaction during tuberization was constructed;and finally directions and potential hotspots for future research were prospected,aiming to provide reference and new ideas for breeding potato varieties with high yield and good quality by precise molecular breeding in future.
