WebMar 20, 2007 · Unlike FAMA, expression of which is restricted to guard mother cells and young guard cells, the bHLH071 and bHLH093 genes are expressed throughout the plant. It therefore appears that, rather than acting in concert with MYB transcription factors, FAMA may function via interaction with other basic helix-loop-helix domain proteins. WebGuard cell function [ edit] Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing. Each guard …
