摘要: 为了进一步了解NF-YB基因家族结构的功能,利用生物信息学手段,系统研究了陆地棉标准系TM-1基因组中NF-YB基因家族的数目、亚细胞定位、染色体分布、进化关系、基序以及组织表达情况。结果表明:TM-1基因组中共有41个NF-YB基因家族成员,它们含有相同的CBFD_NFYB_HMF结构域,大部分定位到细胞核内;41个NF-YB基因家族成员分布在19条染色体上,其中有19组成员在A亚组和D亚组中表现为直系同源基因;进化树分为Ⅰ和Ⅱ 2个小组,每个小组成员间具有相似的基序类型和排列顺序;组织表达分析则发现,在这41个NF-YB基因家族成员中,至少有24个成员可以进行表达,且表现出一定的组织特异性。

Abstract: In order to further understand the structure and function of NF-YB gene family,we have systematically investigated the number,subcellular localization,chromosome distribution,evolutionary relationships,motif and tissue expression pattern of of family in the genome of Gossypium hirsutum L.acc.TM-1 by bioinformatics method.41 NF-YB genes were identified in TM-1 genome;the 41 NF-YB genes contain the same CBFD_NFYB_HMF domain,and most of them were located in nucleus; they distributed on 19 chromosomes,and there were 19 pairs of the genes on the A subgroup and D subgroup were orthologous genes; 41 NF-YB genes can be divided into groupⅠand groupⅡ,and there were similar motif type and arrangement in each group;.24 NF-YB genes were expressed,but the expression pattern varied among different tissues.
