Abstract Small heat shock proteins (sHSPs) constitute a class of molecular chaperones, which are evolutionarily conserved yet diverse group of molecules, rapidly produced in response to stress. In this study, we sought to identify plant sHSPs, especially chaperonin 10 (Cpn10) family members in major evolutionary lineages, and determine their biological significance. Multiple sequence alignment of Cpn10 domains revealed divergent amino acids as well as conserved sites. Phylogenetic tree depicted the diversification and expansion of Cpn10 gene family. During the process of evolution, the Ka/Ks ratio of orthologous and paralogous pairs was

植物中的小热休克蛋白伴侣蛋白 10：进化观点和新兴的功能多样性

摘要 小热休克蛋白（sHSPs）构成一类分子伴侣，是一类进化上保守但多样性的分子，在应激反应中迅速产生。在这项研究中，我们试图确定主要进化谱系中的植物 sHSP，尤其是伴侣蛋白 10 (Cpn10) 家族成员，并确定它们的生物学意义。Cpn10 域的多序列比对揭示了不同的氨基酸以及保守的位点。系统发育树描述了 Cpn10 基因家族的多样化和扩展。在进化过程中，直系同源和旁系同源对的Ka/Ks比为
