从棉花cDNA文库中分离到3个编码AP2／EREBP转录因子的cDNAs序列，命名为GhAP2／EREBP1、GhAP2／EREBP2和GhAP2／EREBP3．利用Real—time RT—PCR对这3个基因表达进行分析，结果表明：GhAP2／EREBP1和GhAP2／EREBP2在棉花纤维中优势表达，而GhAP2／EREBP3在花药中优势表达，在纤维中表达量也较高．这表明上述3个AP2／EREBP转录因子可能在棉花纤维发育过程中起调控作用．

AP2/EREBP transcription factors are known to be unique in plants and exist extensively. They are involved in plant growth, development and many physiological and biochemical processes, such as： pathogen and stress resistance, hormone response, floral organogenesis, and so on. Three cDNAs encoding AP2/EREBP transcription factors were isolated from cotton cDNAs libraries. They were defined GhAP2/EREBP1, GhAP2/EREBP2 and GhAP2/EREBP3. Expression analysis of the 3 genes was carried out by quantitative real-time RT-PCR. The results showed that GhAP...
