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...
探讨超声软指标(USM)颈项透明层(NT)、颈后皮肤皱褶(NF)在产前筛查21-三体综合征中的应用价值。方法 选取2015年7月至2017年8月在安康市妇幼保健院进行产前筛查的3 108例孕早、中期孕妇作为研究对象，通过USM筛查胎儿发生21-三体综合征的情况，以羊膜穿刺及羊水细胞染色体核型分析结果为金标准，通过四格表法计算NT、NF增厚对21-三体胎儿的诊断灵敏度、特异度。
旨在证明α-倒捻子素可以缓解脂多糖（LPS）诱导的IEC-6细胞的炎症并揭示其机制。笔者在体外培养的IEC-6细胞中构建LPS诱导的炎症模型，并通过流式细胞术、酶联免疫吸附测定（ELISA）、定量PCR（Q-PCR）、蛋白印迹（Western blot）的方法检测α-倒捻子素对LPS诱导的炎症是否有缓解作用。结果表明，5 μmol·L-1的α-倒捻子素预处理可以显著降低LPS诱导的前列腺素E2（P...
