Abstract

The main function of histone protein is to provide support to the structure of chromosomes. It helps in binding a long thread of DNA into a more condensed shape to fit into the nucleus. From histone variants, histone H3 () plays a crucial role in plant growth and development. Characterization of histones has not been reported in till now. The objective of this study was to characterize the gene family for molecular breeding of . In this study, 17 members in were identified by performing local BLASTp using members from as a query. Phylogenetic analysis classified genes in seven clades. Sequence logo analysis among , , and showed a higher level of similarity in amino acids. Furthermore, conserveness of genes was also confirmed by Gene Structure Display. Ten paralogous gene pairs were identified in genes in the genome by conducting collinearity analysis. genes have experienced strong purifying selection pressure, with limited functional divergence originating from the segmental and whole-genome duplication, as evidenced by the ratio. The KASP marker was developed for gene. Genotyping was performed on 46 genotypes. This differentiation was based upon the presence of either or allele in the CDS region. The results showed that accessions containing the allele at respective locus showed higher thousand seed weight than that of those accessions that contain the allele. This research provides the basic information to further decipher the function of in soybean.

摘要

组蛋白的主要功能是为染色体结构提供支撑。它有助于将长长的DNA链结合成更紧凑的形状，以适应细胞核。从组蛋白变体来看，组蛋白H3（）在植物生长发育中起着关键作用。迄今为止，尚未见关于[具体植物名称]组蛋白特征的报道。本研究的目的是鉴定[具体植物名称]的[基因名称]基因家族，用于其分子育种。在本研究中，以[另一物种名称]的[基因名称]成员作为查询序列，通过进行本地BLASTp比对，在[具体植物名称]中鉴定出了17个[基因名称]成员。系统发育分析将[具体植物名称]的[基因名称]基因分为七个进化枝。[具体植物名称]、[另一植物名称]和[又一植物名称]之间的序列标识分析表明，它们在氨基酸水平上具有较高的相似性。此外，基因结构展示也证实了[具体植物名称]的[基因名称]基因的保守性。通过共线性分析，在[具体植物名称]基因组的[基因名称]基因中鉴定出了十对旁系同源基因对。[具体植物名称]的[基因名称]基因经历了强烈的纯化选择压力，如[具体比值]所示，其功能分歧有限，源于片段和全基因组复制。开发了针对[具体植物名称]的[基因名称]基因KASP标记。对46个[具体植物名称]基因型进行了基因分型。这种区分是基于CDS区域中[具体等位基因1]或[具体等位基因2]等位基因是否存在。结果表明，在各自位点含有[具体等位基因1]等位基因的[具体植物名称]材料，其千粒重高于含有[具体等位基因2]等位基因的材料。本研究为进一步解析[具体植物名称]中[基因名称]的功能提供了基础信息。
