A cell stores all of its genetic material in its nucleus, in the form of chromosomes, but that’s not all that’s tucked away in there. The nucleus is also home to small bodies called nucleoli — cluster...
Open-Bud Duplicate Loci Are Identified as MML10s, Orthologs of MIXTA-Like Genes on Homologous Chromosomes of Allotetraploid Cotton
棉花 开发花蕾 ob1基因
2024/5/17
通过图位克隆鉴定了控制开发花蕾的ob1基因，是位于D13染色体上的MIXTA-like MYB基因，解释了ob2位点的因果变异。运用全基因组转录组分析技术，发现ob突变体中部分MYB基因和细胞壁生物发生、毛状体分化、细胞分裂素信号转导和细胞分裂的相关基因受到抑制，花瓣生长可能因此受到抑制。
