We are interested in the molecular elucidation of the labile row-type in barley showing irregular spikelet fertility along the spike. The labile row-type is a natural row-type variant predominantly occurring in accessions from Ethiopia. In a recent study, my group mapped the recessive labile (lab) locus to the long arm of chromosome 5H (Youssef et al., 2014). During the proposed project we would like to (i) phenotypically better understand the labile phenotype (macro- and microscopically), (ii) identify the gene underlying the lab locus, and (iii) investigate its molecular function.

我们感兴趣的是在分子上阐明不稳定的行型大麦显示不规则小穗育性沿着穗。不稳定的行型是一种天然的行型变异，主要发生在来自埃塞俄比亚的加入。在最近的一项研究中，我的小组将隐性不稳定（lab）基因座定位到染色体5H的长臂上（Youssef et al.，2014年）。在拟议的项目中，我们希望（i）从表型上更好地了解不稳定表型（宏观和微观），（ii）确定实验室基因座的基因，（iii）研究其分子功能。
