The function of branching spike genes has been successfully suppressed during the development process of barley inflorescence. Gene mutations can reactivate the development of branching spikes in barley, leading to an ectopic expression of the spikelet and its florets on the rachis nodes of branched-spike, an increase in single-floret spikelet per spike and a decrease in flower fertility. Barley branched-spike is a recessive trait genetically controlled by a pairs of nuclear genes. The reported branched-spike genes in barley are distributed on Chr2HS, Chr3HL, and Chr4HS, belonging to different transcription factor gene families, with difference in genetic function, expression mode and interaction characteristic. This article summarized the research progress on the creation methods, agronomic and genetic characteristics of the reported branched-spike mutants, as well as the functions, expression characteristics and transcriptional regulation relationships of the branched-spike genes. We also explored the scientific problems that need to be elucidated and their solution strategies in the genetic research of barley branched-spike mutants.

在大麦花序发育进程中分枝穗基因的功能已被成功抑制,通过基因突变可重新激活大麦分枝穗发育,并可导致小穗及其小花在分枝穗轴节上异位表达、单穗单花小穗增多、小花育性下降等。大麦分枝穗为隐性性状,受1对核基因控制。已报道的大麦分枝穗基因分布在Chr2HS、Chr3HL和Chr4HS上,属不同的转录因子基因家族,其遗传功能、表达模式和互作特性均存在差异。本文对已报道的大麦分枝穗突变体的创制方法、农艺性状与遗传特性,及其分枝穗基因的功能和表达特征等研究结果进行归纳,并探讨了大麦分枝穗突变体遗传研究需要解决的科学问题和应对策略。

在大麦花序发育进程中分枝穗基因的功能已被成功抑制,通过基因突变可重新激活大麦分枝穗发育,并可导致小穗及其小花在分枝穗轴节上异位表达、单穗单花小穗增多、小花育性下降等。大麦分枝穗为隐性性状,受1对核基因控制。已报道的大麦分枝穗基因分布在Chr2HS、Chr3HL和Chr4HS上,属不同的转录因子基因家族,其遗传功能、表达模式和互作特性均存在差异。本文对已报道的大麦分枝穗突变体的创制方法、农艺性状与遗传特性,及其分枝穗基因的功能和表达特征等研究结果进行归纳,并探讨了大麦分枝穗突变体遗传研究需要解决的科学问题和应对策略。

The function of branching spike genes has been successfully suppressed during the development process of barley inflorescence. Gene mutations can reactivate the development of branching spikes in barley, leading to an ectopic expression of the spikelet and its florets on the rachis nodes of branched-spike, an increase in single-floret spikelet per spike and a decrease in flower fertility. Barley branched-spike is a recessive trait genetically controlled by a pairs of nuclear genes. The reported branched-spike genes in barley are distributed on Chr2HS, Chr3HL, and Chr4HS, belonging to different transcription factor gene families, with difference in genetic function, expression mode and interaction characteristic. This article summarized the research progress on the creation methods, agronomic and genetic characteristics of the reported branched-spike mutants, as well as the functions, expression characteristics and transcriptional regulation relationships of the branched-spike genes. We also explored the scientific problems that need to be elucidated and their solution strategies in the genetic research of barley branched-spike mutants.
