BPC (basic penta cysteine)转录因子是植物特有的转录因子家族.在拟南芥中,BPC家族成员广泛而特异的表达.bpc1-1、bpc2、bpc4、bpc6四突变体植株生长、发育多个生理过程受到严重影响.利用中国重要的辣椒Capsicum annuum L. 栽培品种遵辣一号(Zunla-1)及其墨西哥野生祖先种Chiltepin (C. annuum var. glabriusculum)的基因组序列,我们获得了遵辣一号及其野生祖先种基因组中BPC家族成员,并对其进行染色体定位、系统发育和可能的功能等一系列分析.发现了甜辣椒中存在拟南芥中没有的BPC亚家族,以及野生祖先种Chiltepin中存在栽培种遵辣一号中没有的BPC基因.甜辣椒中存在而拟南芥中没有的BPC亚家族,序列中含有拟南芥BPC基因没有的保守基序.在驯化过程中,野生祖先种Chiltepin中存在而栽培种遵辣一号中没有的BPC基因对改变甜辣椒农艺性状的作用,值得进一步的研究.“,”BPC (basic penta cysteine) transcription factors are plant-specific transcription factor family. In Arabidopsis, BPC family members are widely and specifically expressed. bpc1-1, bpc2, bpc4, and bpc6 mutants shows serious defects in plant growth and development. Multiple physiological processes are seriously affected. Using the genome sequence of Capsicum annuum L. Zunla-1 and Chiltepin (C. annuum var. glabriusculum), we obtained the sequence of the BPC family members, and its chromosomal location, phylogenetic and possible functions. A BPC subfamily was found in sweet peppers and not in the Arabidopsis thaliana. And we also identified two BPC genes that was present in the wild ancestor Chiltepin but absent in the cultivated variety Zunla-1. Unique BPC subfamily in C. annuum var. Zunla-1 and C. annuum var. glabriusculum genome has conserved motifs absent in Arabitopsis BPC genes. The effect of the BPC genes, which are absent in the cultivated Capsicum annuum L. Zunla-1, to the agronomic traits of the sweet pepper during the domestication process, is worthy of further study.
