摘要: Mitochondria play an important role in the energy production of plant cells through independent genetic systems. This study has aimed to assemble and annotate the functions of the mitochondrial (mt) genome of Luffa cylindrica. The mt genome of L. cylindrica contained two chromosomes with lengths of 380,879 bp and 67,982 bp, respectively. Seventy-seven genes including 39 protein-coding genes, 34 tRNA genes, 3 rRNA genes, and 1 pseudogene, were identified. About 90.63% of the codons ended with A or U bases, and 98.63% of monomers contained A/T, which contributed to the high A/T content (55.91%) of the complete mt genome. Six genes (ATP8, CCMFC, NAD4, RPL10, RPL5 and RPS4) showed positive selection. Phylogenetic analysis indicates that L. cylindrica is closely related to L. acutangula. The present results provide the mt genome of L. cylindrica, which may facilitate possible genetic variation, evolutionary, and molecular breeding studies of L. cylindrica.
