Transcriptomic analyses between Lycium barbarum and Lycium ruthenicum

ABSTRACT: Lycium barbarum, a member of the Solanaceae family, has been used for more than 2000 years in the traditional Chinese medicine. L. ruthenicum, endemic to northwestern China, is also used as medicine and has had a great influence on the development of Minority Medicine. Previous studies revealed there are many differences between two species, including morphological and phytochemical differences. However, the molecular mechanism of formation of its fruit and associated medicinal and nutritional components is unexplored. In the present studies, for transcriptomic analyses, fruits from 5 developmental stages L. barbarum and L. ruthenicum were collected. KEGG analyses for the DEGs between L. barbarum and L. ruthenicum, revealed that molecular mechanism of fruit formation were distinct obviously during the development process. Moreover, we found that multiple DEGs enriched in “Phenylpropanoid biosynthesis (ID: ko00940”, “Flavonoid biosynthesis” (ID: ko00941) were up-regulated in L. ruthenicum at different developmental stages of fruit. It suggested that biotic and abiotic stress might be responsible for high abundance of antioxidant capacities in L. ruthenicum.

Project description:Watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai) is an important cucurbit crop grown worldwide. Watermelon fruit quality, fertility, and the seed setting rate are closely related to male flower development. In this study, the different developmental stages of flower buds of the watermelon variety Xinteda Zhengkang 9 were distinguished by cytological observation, and transcriptome sequencing analysis was performed subsequently. Acetocarmine staining of anthers was performed and the longitudinal and transverse diameters of the unopened male flower buds were measured. Cytological observations of anthers at different developmental stages showed that the anther grew from the tetrad to the mature stage, and the longitudinal and transverse diameters of the flower buds increased. The length of the male flower buds also changed significantly during development. Transcriptome sequencing analysis at four periods, the tetrad (A group), mononuclear (B group), dikaryophase (C group), and mature stages (D group). Total 16288 differentially expressed genes (DEGs) were detected in the four stages, with the prolongation of developmental stages the number of DEGs increased gradually in the comparison groups, such as there was 2014, 3259, 4628, 1490, 3495 and 1132 DEGs were revealed in six comparison groups (A-VS-B, A-VS-C, A-VS-D, B-VS-C, B-VS-D, and C-VS-D), respectively. Gene ontology (GO) and KEGG enrichment analysis showed that the DEGs were mainly enriched in cellular component and starch and sucrose metabolism, phenylpropanoid biosynthesis and pentose sugar, etc. Finally, we totally screened 59 DEGs were in the six comparison groups, and most of them were up-regulated, interestingly, we find one pollen-specific protein (Cla001608) was significantly up-regulated (the value of log2Fold Change up to 17.32), which indicating that it may play important role in the development of male flowers. This work provides insight into the molecular basis of the developmental stages of male flowers in watermelon and may aid in dominant cross breeding.
