Characterization of the complete chloroplast genome of a purple passion flower variety 'Pingtang No.1' (Passiflora edulia Sims) in China and phylogenetic relationships.

ABSTRACT: Passion flower (Passiflora edulia Sims) is an important fruit that is of great economic importance. In this study, we presented the chloroplast genome of a purple passion flower variety 'Pingtang No.1' in China using BGISEQ-500 sequencing. Its chloroplast genome is 152,621 bp in size. It contains a pair of inverted repeat regions of 25,989 bp, each separating a small single copy region of 13,352 bp and a large single copy region of 85,141 bp. Totally, 111 unique genes, including 77 protein coding genes, 30 tRNAs, and 4 rRNAs, were identified and annotated in the chloroplast genome. Phylogenetic maximum likelihood analysis based on chloroplast genomes of 35 plant species, mainly from the genus Passiflora indicated that 'Pingtang No.1' and yellow passion flower 'IAPAR-123' (Passiflora edulis) cluster together. The chloroplast genome can be used for a better understanding of the evolutionary relationships of plant species of the family Passifloraceae, especially the genus Passiflora.

Project description:Passion fruit (Passiflora edulia Sims), an important tropical and subtropical species, is classified as a respiration climacteric fruit, and its quality deteriorates rapidly after harvest. To elucidate the mechanisms involved in ripening and rapid fruit senescence, phytochemical characteristic analysis and RNA sequencing were performed in purple passion fruit with different treatments, that is, 1-methylcyclopropene (1-MCP) and preservative film (PF). Comprehensive functional annotation and KEGG enrichment analysis showed that starch and sucrose metabolism, plant hormone signal transduction, phenylpropanoid biosynthesis, flavonoid biosynthesis, and carotenoid biosynthesis were involved in fruit ripening. Treatment with PF and 1-MCP significantly affected the transcription levels of passion fruit during postharvest storage. A large number of differentially expressed unigenes (DEGs) were identified as significantly enriched in starch and sucrose metabolism, plant hormone signal transduction and phenylpropanoid biosynthesis at the postharvest stage. The PF and 1-MCP treatments increased superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) gene expression levels and enzyme activities, accelerated lignin accumulation, and decreased β-galactosidase (β-Gal), polygalacturonase (PG) and cellulose activities and gene expression levels to delay cell wall degradation during fruit senescence. The RNA sequencing data for cell wall metabolism and hormone signal transduction pathway-related unigenes were verified by RT-qPCR. The results of this study indicate that the cell wall metabolism and hormone signaling pathways are closely related to passion fruit ripening. PF and 1-MCP treatment might inhibit ethylene signaling and regulate cell wall metabolism pathways to inhibit cell wall degradation. Our results demonstrate the involvement of ripening- and senescence-related networks in passion fruit ripening and may establish a foundation for future research investigating the effects of PF and 1-MCP treatment on fruit ripening.
