Auxins are responsible for a large part of the plant development process. To exert their action, they must move throughout the plant and from cell to cell, which is why plants have developed complex transport systems for indole-3-acetic acid (IAA). These transporters involve proteins that transport IAA into cells, transporters that move IAA to or from different organelles, mainly the endoplasmic reticulum, and transporters that move IAA out of the cell. This research determined that has 12 PIN transporters in its genome. The twelve transporters are expressed during different stages of development in zygotic embryos. Using different bioinformatics tools, we determined the type of transporter of each of the PIN proteins and their structure and possible location in the cell. We also predict the potential phosphorylation sites for each of the twelve-PIN proteins. The data show the presence of highly conserved sites for phosphorylation and those sites involved in the interaction with the IAA.
生长素在植物发育过程中起着很大的作用。为了发挥其作用，它们必须在整个植物体内移动并在细胞间移动，这就是为什么植物已经为吲哚 - 3 - 乙酸（IAA）发展出复杂的运输系统。这些转运蛋白包括将IAA转运到细胞内的蛋白质、将IAA转运到不同细胞器（主要是内质网）或从不同细胞器转运出来的转运蛋白，以及将IAA运出细胞的转运蛋白。这项研究确定[植物名称]的基因组中有12种PIN转运蛋白。这12种转运蛋白在合子胚发育的不同阶段表达。使用不同的生物信息学工具，我们确定了每种PIN蛋白的转运蛋白类型、它们的结构以及在细胞中的可能位置。我们还预测了这12种PIN蛋白各自潜在的磷酸化位点。数据显示存在高度保守的磷酸化位点以及那些参与与IAA相互作用的位点。
