Regulation of cuticle formation during fruit development and ripening in 'Newhall' navel orange (Citrus sinensis Osbeck) revealed by transcriptomic and metabolomic profiling

ABSTRACT: To investigate global genome expression changes during fruit developmemt, We then performed genome-wide expression analyses on the fruit peel at 120 and 150 DAF with RNA-seq approach.A total of 865 genes were identified as differentially expressed, among which 494 genes were up-regulated and 371 genes were down-regulated in the fruits harvested at 150 DAF compared with in those harvested at 120 DAF.In general, data obtained from RNA-seq showed that the genes involved in photosynthesis and tetrapyrrole synthesis were significantly repressed at 150 DAF; in contrast, the genes involved in secondary metabolism including the biosynthesis of wax, terpenoids and phenylpropanoid were significantly induced at 150 DAF.

Unveiling the molecular mechanism involving anthocyanins in pineapple peel discoloration during fruit maturation

Project description:Peel color is a key factor that affects the fruit’s aesthetic and economic values. In Red Sugar pineapple, the peels’ red color reduces during maturation. Limited knowledge is available on the regulation of pineapple peel discoloration, which makes it important to study the molecular mechanisms associated with this important trait. Here, we report that a decrease in anthocyanin biosynthesis is predominantly associated with the pineapple peel color change during maturation. Particularly the exclusive accumulation of cyanidin in 60 days after flowering (DAF) as compared to 120 DAF gives the fruit peel its distinct reddish color. Our findings suggest that the changes in the expression of key structural genes (early and late biosynthetic genes) of the anthocyanin (cyanidin) biosynthesis pathway are responsible for peel discoloration. Based on a gene co-expression analysis and a transient expression, we identified two transcription factors i.e., AcHOX21 and AcMYB12, and showed that their downregulation leads to the reduced anthocyanin accumulation with fruit maturation.

Microarray analysis of fruit flesh of European pear M-bM-^@M-^XLa FranceM-bM-^@M-^Y during fruit development

Project description:Comprehensive investigation of gene expression during fruit development and ripening in European pear (Pyrus communis). Gene expression of fruit flesh development of European pear was measured from -7 to 182 days after full bloom (DAFB). 150 DAFB is harvested stage and 182 DAFB is after ripening by chilling treatment (2M-BM-0C 12 days, then 15M-BM-0C 20 days).

Comparative transcriptomic analysis reveals the roles of microtubule-related genes and transcription factors in fruit length regulation in cucumber (Cucumis sativus)

Project description:Cucumber (Cucumis sativus L.) fruit is a type of fleshy fruit that is harvested immaturely. Early fruit development directly determines the final fruit length and diameter, and consequently the fruit yield and quality. Different cucumber varieties display huge variations of fruit length, but how fruit length is determined at the molecular level remains poorly understood. To understand the genes and gene networks that regulate fruit length in cucumber, high throughout RNA-seq data were used to compare the transcriptomes of early fruit from two near isogenic lines with different fruit lengths. 3955 genes were found to be differentially expressed, among which 2368 genes were significantly up-regulated and 1587 down-regulated in the line with long fruit. Microtubule and cell cycle related genes were dramatically activated in the long fruit, and transcription factors were implicated in the fruit length regulation in cucumber. Thus, our results built a foundation to dissect the molecular mechanism of fruit length control in cucumber, a key agricultural trait of significant economic importance.

Transcriptome analysis of tomato introgression line during fruit development.

Project description:We performed transcriptome analyses throughout fruit development using the tomato cultivar M82 and its near-isogenic line IL8-3, with interesting and useful traits such as a high content of soluble solids. To identify genes that show differential expression between M82 and IL8-3 fruits, we used a custom microarray containing 43,803 tomato probes. Some genes, such as cell wall invertase and sucrose synthase genes, which are encoded by LIN6 (Solyc10g083290) and TOMSSF (Solyc12g009300) respectively, are well known to play a key role in the sink function of fruit. In this study, the levels of LIN6 and TOMSSF transcripts were higher in IL8-3 than in M82 fruit at 20 and 30 DAF, which are developmental stages for starch accumulation and increased hexose content, respectively, in IL8-3 fruit (Ikeda et al. 2013), and decreased to the level of M82 at ripening stage. Similar patterns were observed in many metabolites of glycolysis and the pentose phosphate pathway as well as metabolites in starch and sucrose metabolism. Gene expressions during fruit development were analyzed. Three biological replicates were prepared for each stage, and a total of 24 samples were analyzed.
