RT-PCR analysis of GhWBC1 expression in different aerial organs of cotton cv Xu-142 and fl mutant. Total RNAs were isolated from hypocotyls (H), cotyledons (C), and young true leaves (L) of the 10-d-old seedlings and from 9-DPA ovules (O) or fibers (F). The PCR was conducted by 27 cycles of PCR amplification with primers GH3 and GH4.
