Identification of Genes Controlling Cotton Fiber Length
April 27, 2007| |
Cotton fiber is an extremely elongated single cell. It is considered as an ideal system for studying the mechanisms controlling plant cell elongation and research on the area is attractive because of its theoretical and practical importance.
A study by Chinese researchers has shown that the mechanism responsible for cotton fiber elongation is mediated by calcium signal transduction. This mechanism has been reported by other research to play important roles in the growth of plant cells, such as pollen tube and root hair cells.
The group of Peng Gao used a technique called suppression subtractive hybridization (SSH) to identify genes that are specifically or preferentially expressed in cotton fiber cells. Four genes were found to have high homology to calcium signaling components, calmodulin (CaM), glutamate decarboxylase (GAD) and calcineurin B-like (CBL) protein-interacting protein kinases (CIPKs).
