Plants are exposed to a constantly changing environment from which they cannot escape. Instead, they alter development to produce a form better adapted to the new environment. The hormone auxin controls many important events in plant development such as defining where leaves form, where shoots and root branch and turning roots towards gravity. Auxin is directionally transported from cell to cell dependent upon the polar localization of PINFORMED (PIN) transport proteins to a particular side of the cell membrane. Many of the environmental responses of plant growth are achieved by changing PIN localization and hence cell polarity, tissue growth and organization.

植物暴露在一个不断变化的环境中，它们无法逃脱。相反，它们改变发育，以产生更好地适应新环境的形式。生长素激素控制着植物发育中的许多重要事件，例如确定叶子的形成位置，芽和根的分支的位置以及使根转向重力。生长素在细胞间的定向转运依赖于PINFORMED（PIN）转运蛋白在细胞膜特定一侧的极性定位。植物生长的许多环境响应是通过改变PIN定位并因此改变细胞极性、组织生长和组织来实现的。
