Sup基因家族在雌雄异株木本植物中的表达及其调控模式的报道。系统发育和核苷酸多样性分析表明，PtoSUP1高度保守，并经历了较强的纯化选择。超人(SUP)调控雌雄同株植物花发育的分子基础已被广泛研究，但对雌雄异株木本植物中的SUP基因家族知之甚少。在这项研究中，我们系统地研究了杨树SUP基因家族的多样性，整合了基因组组织、表达和系统发育数据。Sup家族成员在花发育过程中表现出性别特异性表达。对稀有的雌雄同株杨花的转录谱分析表明，PtoSUP1 mRNA的显著降低可能对雌雄同株杨花的雄蕊发育具有重要意义。我们发现，杨树SUP基因的编码区高度保守，外显子区域的同义位点在进化过程中经历了强烈的纯化选择。这些结果表明，SUP基因在雌雄异株植物的花发育中起着重要的作用。SUP的表达分析揭示了雌雄同株杨树花发育的可能调控机制。这些发现为SUP功能进化的机制提供了重要的洞察力，并可能有助于通过工程手段调控花的发育，从而培育出优良的树种。
SUP gene family expression and regulation patterns reported in dioecious woody plant. Phylogenetic and nucleotide diversity analysis indicated PtoSUP1 is highly conserved and has undergone strong purifying selection. The molecular basis of SUPERMAN (SUP) regulation during floral development in monoecious plants has been extensively studied, but little is known of the SUP gene family in dioecious woody plants. In this study, we systematically examined the diversification of the SUP gene family in Populus, integrating genomic organization, expression, and phylogeny data. SUP family members showed sex-specific expression throughout flower development. Transcript profiling of rare gynomonoecious poplar flowers revealed that a significant reduction in PtoSUP1 mRNA might be important for stamen development in gynomonoecious poplar flowers. We found that the coding regions of Populus SUP genes are very highly conserved and that synonymous sites in exon regions have undergone strong purifying selection during SUP evolution in Populus. These results indicate that SUP genes play an important role in floral development of dioecious plants. Expression analysis of SUP suggested possible regulatory mechanisms for gynomonoecious poplar flower development. These findings provide an important insight into the mechanisms of the evolution of SUP function and may help enable engineered regulation of flower development for breeding improved tree varieties.
