Colored rice is gaining popularity due to its use in creative agriculture and the value of healthy consumption. However, the quality and yield characteristics of most rice varieties still need to be improved. Revealing the genetic background of colored rice is of great significance to promote crop improvement. Here, the completed chloroplast (cp) genome sequence of yellow colored voucher HSAGSDYD1802 was sequenced and reported. It was a 134,502 bp circular DNA with a typical quadripartite structure, consisting of two reverse repeat regions (IR and IR, 20,804 bp) separated by a large single-copy region (LSC, 80,547 bp) and a small single-copy region (SSC, 12,347 bp). The total GC content was 39%. The cp genome encoded 146 genes, containing 100 protein-coding genes, 8 rRNAs, and 38 tRNA genes. Phylogenetic analysis indicated that voucher HSAGSDYD1802 was closely related to L. TN1, RP Bio-226 and IR8. This study enriches the genetic information of colored rice and is helpful for future molecular breeding.
有色稻因其在创意农业中的应用和健康消费价值而越来越受欢迎。然而,大多数水稻品种的品质和产量特性仍有待提高。揭示有色稻的遗传背景对促进作物改良具有重要意义。在此,对黄色凭证HSAGSDYD1802的完整叶绿体(cp)基因组序列进行了测序并报告。它是一个134,502 bp的环状DNA,具有典型的四分体结构,由两个反向重复区域(IR和IR,20,804 bp)组成,中间被一个大单拷贝区域(LSC,80,547 bp)和一个小单拷贝区域(SSC,12,347 bp)隔开。总GC含量为39%。cp基因组编码146个基因,包括100个蛋白质编码基因、8个rRNA和38个tRNA基因。系统发育分析表明,凭证HSAGSDYD1802与L. TN1、RP Bio-226和IR8密切相关。本研究丰富了有色稻的遗传信息,有助于未来的分子育种。
