Increasing evidence suggests that posttranscriptional regulation is a key player in the transition between mature pollen and the progamic phase (from pollination to fertilization). Nonetheless, the ac...
GhGPAT12/25 Are Essential for the Formation of Anther Cuticle and Pollen Exine in Cotton (Gossypium hirsutum L.)
GhGPAT12 GhGPAT25 陆地棉 旁系同源基因
2024/4/16
GhGPAT12和GhGPAT25为一对位于陆地棉A12/D12染色体上编码甘油-3-磷酸酰基转移酶（GPAT）的旁系同源基因。GhGPAT12/25在发育早期的花药中特异表达，其转录本主要富集于绒毡层和花粉外壁。真核表达实验表明GhGPAT12/25具有sn-2酰基转移酶活性。CRISPR/Cas9介导的基因敲除实验发现GhGPAT12和GhGPAT25存在功能冗余，两基因的同时敲除导致彻底的雄...
