Identification of TPX2 Gene Family in Upland Cotton and Its Functional Analysis in Cotton Fiber Development.

ABSTRACT: Microtubules (MTs) are of importance to fiber development. The Xklp2 (TPX2) proteins as a class of microtubule-associated proteins (MAPs) play a key role in plant growth and development by regulating the dynamic changes of microtubules (MTs). However, the mechanism underlying this is unknown. The interactions between TPX2 proteins and tubulin protein, which are the main structural components, have not been studied in fiber development of upland cotton. Therefore, a genome-wide analysis of the TPX2 family was firstly performed in Gossypiumhirsutum L. This study identified 41 GhTPX2 sequences in the assembled G. hirsutum genome by a series of bioinformatic methods. Generally, this gene family is phylogenetically grouped into six subfamilies, and 41 G. hi
