Abstract

The figleaf gourd (Cucurbita ficifolia Bouché), is a member of the Cucurbitaceae. Figleaf gourd genotypes are exclusively used as a rootstock for cucumber owing to their high physiological compatibility with cucumber. In this study, the complete chloroplast (cp) genome of C. ficifolia was assembled. The cp genome of C. ficifolia was 157,631 bp in length, it consists of a pair of inverted repeats (IRa and IRb) regions (25,638 bp) separated by the large single-copy (LSC, 88,211 bp) and small single-copy (SSC, 18,144 bp) regions. The cp genome encodes 111 unique genes, including 80 protein-coding genes, 27 transfer RNA genes, and four ribosomal RNA genes. The overall GC content of C. ficifolia cp genome was 37.2%. The phylogenetic tree of Cucurbitaceae showed that C. ficifolia was clustered into genus Cucurbita and the bootstrap value is 100%.

摘要

无花果（Cucurbita ficifolia Bouché）是葫芦科的一员。无花果基因型因其与黄瓜的高生理相容性而专门用作黄瓜的砧木。在这项研究中，组装了C. ficifolia的完整叶绿体 (cp) 基因组。C. ficifolia cp 基因组长度为 157,631 bp，它由一对反向重复（IRa 和 IRb）区域（25,638 bp）组成，由大单拷贝（LSC，88,211 bp）和小单拷贝（ SSC，18,144 bp) 区域。cp 基因组编码 111 个独特的基因，包括 80 个蛋白质编码基因、27 个转移 RNA 基因和 4 个核糖体 RNA 基因。C. ficifolia的总GC含量cp 基因组为 37.2%。葫芦科系统发育树显示，C. ficifolia聚类为葫芦属，bootstrap 值为100%。
