Genetic variation in MYB5_A12 is associated with fibre initiation and elongation in tetraploid cotton
MYB5_A12 陆地棉 纤维起始 纤维伸长 表达水平 海岛棉
2024/5/17
本研究发现MYB5_A12在陆地棉（SG747）纤维起始及伸长早期的表达水平显著低于海岛棉（GZ75）；通过QTL共定位分析发现，海岛棉GbMYB5_A12的等位基因型与纤维长度（FL）、纤维强度（FS）和衣分（LP）等性状显著正相关，其启动子区的顺式作用元件TFmatrixID_0063 (GATGTTGT)的自然变异可能导致海陆等位基因差异表达；通过酵母单杂及双荧光素酶报告基因实验验证了RAV...
