大豆病程相关蛋白PR-5及其同源蛋白TPLs 的生物信息学分析
大豆病程相关蛋白 类甜蛋白 系统进化分析 生物信息学分析
2016/7/22
大豆病程相关蛋白PＲ-5 又称为类甜蛋白TLPs，广泛分布于高等植物体内，各种生物和非生物胁迫诱导( 病原微生物、渗透胁迫，机械损伤和植物激素等) 均可诱导其表达。本研究以PＲ-5 编码基因Glyma01g42670. 1 为目的基因，对该基因及其同源蛋白的结构和功能进行了分析; 通过生物信息学的方法，共筛选获得42 条大豆TLPs 蛋白质序列，并用Mega 4. 1 软件构建其系统进化树; 同时...
旨在探讨济宁青山羊出生后发育过程中雌激素受体（Estrogen receptor, ERα和ERβ）和孕激素受体（Progesterone receptor, PR）在子宫的定位及其mRNA的表达规律。利用SABC法检测ERα、ERβ和PR在不同日龄组子宫的分布；以GAPDH为内参基因，qRT-PCR法检测3种mRNA的相对表达量。结果显示，ERα、ERβ 和PR阳性物质主要见于腔上皮、腺上皮、基...
本研究旨在探讨济宁青山羊出生后发育过程中乳腺组织内雌激素受体α(ERα)和 孕激素受体(PR)免疫阳性细胞的分布及平均光密度和mRNA分子水平的表达规律。应用SP免疫组化法和图像分析方法检测ERα和PR在济宁青山羊乳腺内的分布；以GAPDH为内参基因，qRT-PCR方法检测 ERα和PR mRNA的相对表达量。结果表明, ERα和PR阳性染色主要见于乳腺组织内的血管内皮细胞、基质细胞和腺管上皮细胞...
