GAST (GA-stimulated transcript)-like genes have been reported as targets of GA regulation in some plant species. In this study, we isolated seven GAST-like cDNAs from cotton (Gossypium hirsutum) cDNA libraries (designated as GhGASL1-GhGASL7). Meanwhile, the genomic DNA clones corresponding to the seven GhGASL genes were isolated by using PCR amplification technique. Analysis of gene structure revealed that four genes (GhGASL1/3/5/6) contain two exons and one intron, while the rest have four exons and three introns. All of the deduced GhGASL proteins contain a putative signal peptide in the N-t...
