超氧化物歧化酶（SOD）是一组重要的、普遍存在的酶，在植物生长发育中起着重要的作用。以前，这个基因家族已经在拟南芥和水稻中进行了研究;它还没有在棉花中被鉴定。本研究首次对棉花SOD基因家族进行了全基因组分析。结果表明，在亚洲棉和雷蒙棉中共鉴定出SOD基因家族的10个基因，其中Cu-Zn-SOD基因6个，Fe-SOD基因2个，Mn-SOD基因2个。染色体分布分析表明，超氧化物歧化酶基因分布在亚洲棉的7条染色体和雷蒙棉的8条染色体上。片段重复是SOD基因家族的主要重复事件，也是SOD基因家族扩展的主要原因。基因结构和蛋白质结构分析表明SOD基因具有保守的外显子/内含子排列和基序组成。基于基因芯片的表达分析表明，SOD基因在非生物胁迫中具有重要的功能。此外，组织特异性表达谱揭示了SOD基因在棉花不同器官发育中的功能差异。本研究为棉花SOD基因家族的功能研究提供了新的思路。本研究的结果有助于理解SOD基因家族在棉花生活史各个方面的作用。
Superoxide dismutase (SOD) as a group of significant and ubiquitous enzymes plays a critical function in plant growth and development. Previously this gene family has been investigated in Arabidopsis and rice; it has not yet been characterized in cotton. In our study, it was the first time for us to perform a genome-wide analysis of SOD gene family in cotton. Our results showed that 10 genes of SOD gene family were identified in Gossypium arboreum and Gossypium raimondii, including 6 Cu-Zn-SODs, 2 Fe-SODs, and 2 Mn-SODs. The chromosomal distribution analysis revealed that SOD genes are distributed across 7 chromosomes in Gossypium arboreum and 8 chromosomes in Gossypium raimondii. Segmental duplication is predominant duplication event and major contributor for expansion of SOD gene family. Gene structure and protein structure analysis showed that SOD genes have conserved exon/intron arrangement and motif composition. Microarray-based expression analysis revealed that SOD genes have important function in abiotic stress. Moreover, the tissue-specific expression profile reveals the functional divergence of SOD genes in different organs development of cotton. Taken together, this study has imparted new insights into the putative functions of SOD gene family in cotton. Findings of the present investigation could help in understanding the role of SOD gene family in various aspects of the life cycle of cotton.
