植物aqps构成几个蛋白家族，包括 质膜固有蛋白 （pip）家族，该家族又分为pip1和pip2亚家族。当其他aqps管理细胞器之间的底物运输时，pips控制分子在质膜（pms）上的转运。

2024年3月1日 · Genomic research has characterized four or five well-established AQP subfamilies: PIPs, TIPs, NIPs, SIPs, and XIPs. Table 1 demonstrates that the majority of monocotyledons plant species possess four AQP families, excluding XIP members. However, specific species within the Fabaceae family (M. truncatula L.,

2022年1月3日 · Recently, the constitutive overexpression of the poplar root-specific AQP gene PtoPIP1;1 in Arabidopsis has been reported to accelerate the flowering process of the transgenic lines (Leng et al., 2021). All these pieces of research suggest …

在高等植物中，依据序列同源性及亚细胞定位不同，AQPs可以分为五个亚家族： 质膜内在蛋白 （Plasma membrane intrinsic proteins，PIPs），主要定位于细胞质膜； 液泡膜内在蛋白 （Tonoplast intrinsic proteins，TIPs），主要定位于液泡膜； 类NOD26膜内在蛋白 （NOD26-like intrinsic proteins，NIPs），定位于质膜及内质网等亚细胞器； 小碱性膜内在蛋白 （Small basic intrinsic proteins，SIPs），定位内质网中； 未知功能膜内在蛋白 （X-intrinsic …

2017年4月27日 · Based on phylogenetic analysis, plant AQPs are grouped into five subfamilies: (i)plasma membrane intrinsic proteins (PIPs), (ii) tonoplast intrinsic proteins (TIPs), (iii) nodulin26-like intrinsic...

2018年3月26日 · In plants, members of the plasma membrane intrinsic protein (PIP) AQP subfamily are important for the maintenance of the plant water status through the control of cell and tissue hydraulics. The PIP subfamily is subdivided into two groups: PIP1 and PIP2 that exhibit different water-channel activities when expressed in Xenopus oocytes or yeast ...

2014年10月1日 · Aquaporin protein (AQP), also called major intrinsic proteins (MIPs), control water transport and are ubiquitously distributed in higher plants; the AQP families consist of numerous homologous genes, e.g., 35 in Arabidopsis (Johanson et al., 2001) and 34 in rice (Nguyen et al., 2013).

研究发现，水通道蛋白（AQP）在植物生长发育及响应盐、碱等非生物胁迫方面发挥重要的调控作用。 水通道蛋白 属于膜内在蛋白家族（major intrinsic protein，MIP），参与调节植物细胞分化和伸长、叶片气孔开闭、木质部栓塞修复、养分运输和开花等多种生理生化过程，还能转运水分和甲酰胺、硼酸、尿素、硅酸等其他中性小分子物质，来维持植物体内的离子及渗透平衡。 随着人们对AQP研究的不断深入，植物中越来越多编码AQP的基因得到了分离和鉴定。 然而，目前关于 …

2017年1月25日 · In this study, we identified 59 AQP genes in the B. rapa database and Br135K microarray dataset. Phylogenetic analysis revealed four distinct subfamilies of AQP genes: plasma membrane intrinsic proteins (PIPs), tonoplast intrinsic proteins (TIPs), NOD26-like intrinsic proteins (NIPs) and small basic intrinsic proteins (SIPs).

Looking at the AQP subfamilies, most plasma membrane intrinsic proteins (PIPs) and some tonoplast intrinsic proteins (TIPs) have a high level of expression, while NOD26-like proteins (NIPs) are present at a much lower level.
