热激转录因子（HSFs）参与植物对环境胁迫的应答和发育，如热胁迫和开花发育。根据HSF基因家族的结构特征，植物中的HSF基因可分为三种主要类型（HSFA、HSFB和HSFC）。利用HSF基因的保守结构域，我们在13个棉花基因组中鉴定了621个HSF基因，包括8个二倍体和5个四倍体基因组。系统发育分析表明，13个棉花基因组中的HSF基因可分为两个不同的簇：一个簇包含HSFA和HSFC的所有HSF基因，另一个簇包含HSFB的所有HSF基因。对拟南芥、草棉（A1）、亚洲棉（A2）、雷蒙棉（D5）和陆地棉（AD 1）基因组中HSF基因的比较分析表明，4个HSF基因遗传自所有现有棉花A基因组的共同祖先A0。HSF基因家族成员在G. herbaceum（A1）基因组与G. arboretum（A2）和G. hirsutum（AD 1）A基因组。而G. raimondii（D5）与G. hirsutum（AD 1）D基因组。对HSF基因的串联重复（TD）事件分析表明，不同棉花基因组间的蛋白质编码基因都经历了TD事件，但在苏氏棉（D1）基因组中只检测到两个基因的串联阵列。HSF基因在G.结果表明，在陆地棉（AD 1）和海岛棉（AD 2）基因组中，表达的HSF基因分别被分为两个不同的类群，且在相同的非生物胁迫下，两个基因组中表达的HSF基因表现出完全不同的表达模式。本研究为深入研究HSF基因在不同棉花基因组中的进化历史和表达特征提供了新的思路，也为植物HSF基因家族的研究提供了广泛的应用模型。
Heat shock transcription factors (HSFs) are involved in environmental stress response and plant development, such as heat stress and flowering development. According to the structural characteristics of the HSF gene family, HSF genes were classified into three major types (HSFA, HSFB, and HSFC) in plants. Using conserved domains of HSF genes, we identified 621 HSF genes among 13 cotton genomes, consisting of eight diploid and five tetraploid genomes. Phylogenetic analysis indicated that HSF genes among 13 cotton genomes were grouped into two different clusters: one cluster contained all HSF genes of HSFA and HSFC, and the other cluster contained all HSF genes of HSFB. Comparative analysis of HSF genes in Arabidopsis thaliana, Gossypium herbaceum (A1), Gossypium arboreum (A2), Gossypium raimondii (D5), and Gossypium hirsutum (AD1) genomes demonstrated that four HSF genes were inherited from a common ancestor, A0, of all existing cotton A genomes. Members of the HSF gene family in G. herbaceum (A1) genome indicated a significant loss compared with those in G. arboretum (A2) and G. hirsutum (AD1) A genomes. However, HSF genes in G. raimondii (D5) showed relative loss compared with those in G. hirsutum (AD1) D genome. Analysis of tandem duplication (TD) events of HSF genes revealed that protein-coding genes among different cotton genomes have experienced TD events, but only the two-gene tandem array was detected in Gossypium thurberi (D1) genome. The expression analysis of HSF genes in G. hirsutum (AD1) and Gossypium barbadense (AD2) genomes indicated that the expressed HSF genes were divided into two different groups, respectively, and the expressed HSF orthologous genes between the two genomes showed totally different expression patterns despite the implementation of the same abiotic stresses. This work will provide novel insights for the study of evolutionary history and expression characterization of HSF genes in different cotton genomes and a widespread application model for the study of HSF gene families in plants.
