摘      要：Background Photosystem II(PSII)constitutes an intricate assembly of protein pigments,featuring extrinsic and intrinsic polypeptides within the photosynthetic *** low-molecular-weight transmembrane protein PsbX has been identified in PSII,which is associated with the oxygen-evolving *** expression of PsbX gene protein is regulated by ***’s central role involves the regulation of PSII,facilitating the binding of quinone molecules to the Qb(PsbA)site,and it additionally plays a crucial role in optimizing the efficiency of *** these insights,a comprehensive understanding of the PsbX gene’s functions has remained *** In this study,we identified ten PsbX genes in Gossypium hirsutum *** phylogenetic analysis results showed that 40 genes from nine species were classified into one *** resulting sequence logos exhibited substantial conservation across the N and C terminals at multiple sites among all Gossypium ***,the ortholo-gous/paralogous,Ka/Ks ratio revealed that cotton PsbX genes subjected to positive as well as purifying selection pressure might lead to limited divergence,which resulted in the whole genome and segmental *** expression patterns of GhPsbX genes exhibited variations across specific tissues,as indicated by the ***,the expression of GhPsbX genes could potentially be regulated in response to salt,intense light,and drought ***,GhPsbX genes may play a significant role in the modulation of photosynthesis under adverse abiotic *** We examined the structure and function of PsbX gene family very first by using comparative genom-ics and systems biology approaches in *** seems that PsbX gene family plays a vital role during the growth and development of cotton under stress ***,the results of this study provide basic information to unveil the molecular and physiological function of PsbX genes of cotton plan
