摘要  分蘖是影响禾谷类作物产量潜力和环境适应性的一个重要性状,它既受内源(遗传)因子的控制,也受外源(环境)条件的影响。水稻与小麦分蘖的生理与分子调控已有大量研究,但相应的研究大麦上仍较少报导。作者在本综述中基于近年来生物信息学的研究成果将所有已知的大麦分蘖相关基因全部绘制在染色体物理图谱上,其中一些为首次在染色体上定位。本文还从遗传、生理和环境层面上讨论了分蘖的调控机理,构建了激素与糖代谢调控分蘖的遗传网络。同时,还阐述了环境因子与种植制度影响分蘖发生的原因。本综述可加深对大麦分蘖与相关发育特性生理与遗传调控机制的理解。

Abstract  Tillering is a crucial trait closely associated with yield potential and environmental adaptation in cereal crops, regulated by the synergy of endogenous (genetic) and exogenous (environmental) factors.  The physiological and molecular regulation of tillering has been intensively studied in rice and wheat.  However, tillering research on barley is scarce.  This review used the recent advances in bioinformatics to map all known and potential barley tiller development genes with their chromosomal genetic and physical positions.  Many of them were mapped for the first time.  We also discussed tillering regulation at genetic, physiological, and environmental levels.  Moreover, we established a novel link between the genetic control of phytohormones and sugars with tillering.  We provided evidence of how environmental cues and cropping systems help optimize the tiller number.  This comprehensive review enhances the understanding of barley’s physiological and genetic mechanisms controlling tillering and other developmental traits.
