High-resolution temporal dynamic transcriptome landscape reveals a GhCAL-mediated flowering regulatory pathway in cotton (Gossypium hirsutum L.)
棉花开花 相关基因 GhCAL
2024/5/17
本研究利用不同熟性的棉花高分辨率时间动态转录组，鉴定到棉花开花相关基因GhCAL，并对其介导的棉花开花调节途径进行了解析。研究发现GhCAL基因沉默的转基因棉花植株花芽分化和开花时间显著延迟，GhCAL能够与GhAP1-A04/GhAGL6-D09形成异源二聚体，同时调节GhAP1-A04和GhAGL6-D09的表达。GhAP1-A04和GhAGL6-D09沉默的棉花植株也表现出明显的开花延迟。因...

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...
