Genome-wide identification of NF-YA gene family in cotton and the positive role of GhNF-YA10 and GhNF-YA23 in salt tolerance
全基因组分析 雷蒙德氏棉 亚洲棉 海岛棉 陆地棉
2024/5/17
本研究基于全基因组分析，在雷蒙德氏棉、亚洲棉、海岛棉和陆地棉基因组中分别鉴定得到16、16、31和29个NF-YA基因。通过进化树分析将NF-YA基因分为4个亚组。结构分析表明NF-YA基因在棉属进化过程中相对保守。荧光定量显示GhNF-YAs可能通过ABA和 MeJA的调控通路响应盐和干旱。VIGS沉默GhNF-YA10和GhNF-YA23的表达，能显著降低棉花对盐的抗性，表明这两个基...
陆地棉NF-YA基因家族的全基因组鉴定与功能分析
陆地棉 NF-YA基因家族 生物信息学 表达分析 病毒诱导基因沉默（Virus-induced gene silencing, VIGS）
2021/1/11
【目的】通过对陆地棉NF-YA基因家族进行全基因组鉴定，分析其表达特性，鉴定其中与棉花开花相关的基因。【方法】利用生物信息学方法系统分析了其理化性质、基因结构、共线性、Ka/Ks、顺式作用元件和表达模式，实时荧光定量聚合酶链反应（Polymerase chain reaction，PCR）分析表达特征，采用病毒诱导基因沉默技术验证基因功能。【结果】陆地棉中鉴定到29个NF-YA基因家族成员，分为5...

与常规地震采集参数，如覆盖次数和面元大小等相比，在高密度三维地震采集设计中，讨论炮密度和道密度参数对叠前成像的影响显得更为重要。在导出炮密度、道密度与面元、覆盖次数的关系的基础上，通过对YA高精度三维观测系统及其五种退化方案叠前偏移效果、信噪比和采集成本的对比分析，本文认为：①由于地震数据的频带是有限的，叠前偏移效果与炮密度、道密度关系曲线存在一个门槛值，在门槛值内信噪比随炮密度或道密度的增加而明...
