Abstract: Arabidopsis GLABRA2 (AtGL2), a transcription factor, plays critical roles in the differentiation of trichome cells and root hair cells. However, the function of GL2 homologous genes in cotton fiber differentiation and development is still unclear. In this paper, transcription profiles of four putative cotton HOX ORFs homologous with AtGL2 were investigated. Multiple sequence alignment revealed that these 4 GhHOX proteins shared 95%, 71%, 72%, and 63% identity with AtGL2 in the homeobox conserved domain, respectively. Real-time RT-PCR analysis indicated that GhHOX1, GhHOX3 and GhHOX4 expressed in cotton elongating fiber cells preferentially. Moreover, GhHOX3 showed significant higher expression level in the ovules of Xuzhou 142 than in its fuzz-free and lint-free mutant ovules at the initiation stage. The results suggested that the GL2 homologous genes of cotton may play important roles in fiber initiation and elongation.
