Bioinformatic Analysis of Tomato Aquaporin Gene Family
Plant aquaporins not only transport water in the root system, but also have a diversity of substrates and cell positioning, and thus are important for the plant physiology and development processes, including seed germination, lateral root occurrence, carbon fixation and nutrient absorption. There were 44 aquaporin genes in the tomato genome. These genes can be divided into TIP, PIP, NIP and SIP subfamilies. These four subfamilies have different functions and subcellular localization. The five aquaporin genes on tomato chromosome 10 and one aquaporin gene on chromosome 1 were orthologous aquaporins, and all of them belonged to PIP subfamily. The expression of aquaporin genes in tomato roots was higher than that in leaves and flowers. However, Solyc03 g096290.2.1 and Solyc01 g094690.2.1 had the highest expression in flowers. In addition, Solyc06 g074820.2.1 and Solyc08 g081190.2.1 expression levels were stable at high levels. These genes may function not only in the uptake and transportation of water, but also in the presence of other transport substrates, and further study is needed to identify whether they have a regulatory role in stress tolerance and development of plants. Tomato genome aquaporin genes search and analysis are of great significance for tomato molecular biology research and germplasm improvement.
