Polar auxin transport

Polar auxin transport pathway of rice. Even though we have shown a representative diagram of influx and efflux proteins on different but adjacent cells, the auxin influx and efflux transport proteins when present in the same cell, are often located in the plasma membrane of cell's opposite side or on the sides (left/right). All the different paralogs of influx and efflux proteins may not be present in the same cell. Often their expression and localization is tissue, cell, organ and development stage specific. This helps in directing the flow of auxin towards 'auxin maxima' sites in plant organs and cells as needed. In some cases auxin can permeate through the plasma membrane.

水稻极性生长素转运途径。尽管我们已经展示了不同但相邻细胞中流入和流出蛋白的代表图，但当流入和流出蛋白存在于同一细胞中时，它们通常位于细胞相对的质膜或两侧（左侧/右侧）。并非所有流入和流出蛋白的同源物都存在于同一细胞中。它们的表达和定位通常具有组织、细胞、器官和发育阶段特异性。这有助于根据需要引导生长素流向植物器官和细胞中的'生长素最大值'位点。在某些情况下，生长素可以穿透质膜。
