Project description:Twelve chili pepper accessions, six domesticated, four wild and two F1 crosses were studied. RNA-Seq experiments were performed with fruits from each accession at 7 different times after anthesis. Additionally, samples of seedlings from two accessions were evaluated. The data set is comprised by 179 samples, that in total have more than 3 billion reads map to the Capsicum annuum genome.

Project description:The quality of the pepper fruit is significantly influenced by the properties of its surface such as color, glossiness and texture. The fruit surface is composed of a peel containing several layers including the cuticle, epidermis and the hypodermis. The peel acts as a protective barrier against biotic and abiotic stresses and is the most critical tissue affecting water loss during post harvest storage. The peel is composed of an outer epidermis with thick waxy (lipid) cuticle and few cell layers of thick-walled hypodermal cells. Despite its agronomic importance and due to the fact that the majority of studies in fruits have been conducted using flesh and peel tissues as a whole, the biochemical and genetic bases of variation in peel properties are largely unknown. In this proposal we aim to determine peel-specific gene expression in pepper by micro array hybridizations of peel and flesh RNA extracted at different developmental stages of the fruit. The cultivar Celica (Capsicum annuum) that has a large blocky fruit will be used for studying gene expression in the peel and flesh. Plants were grown in the greenhouse during the spring of 2006. Fruits were harvested at three developmental stages: young- 10 days after anthesis, mature green- 30 days after anthesis and ripe red- 45 days after anthesis. These stages were chosen because each represents a distinct phase in fruit development. At each stage, a biological replicate consists of bulked tissue from 3 fruits from each of 3 plants (a total of 9 fruits). We have a total of 4 biological replicates. For each fruit, the peel was separated from the flesh by manual dissection using thin forceps and scalpel blade. Peel and flesh samples were immediately frozen in liquid nitrogen and stored at -800C until RNA extraction. Total RNA was extracted using the GenElute Mammalian Total RNA Miniprep kit (Sigma).

Project description:Background The set of all mRNA molecules present in a cell constitute the transcriptome. The transcriptome varies depending on cell type as well as in response to internal and external stimuli during development. Chili pepper is an economically and culturally important horticultural crop as well as a good model for the study of secondary metabolism during fruit development. Here we present a study of the changes that occur in the transcriptome of chili pepper fruit during development and ripening. Results RNA-Seq was used to obtain transcriptomes of whole Serrano-type chili pepper fruits (Capsicum annuum L.; 'Tampiqueno 74') collected at 10, 20, 40 and 60 days after anthesis (DAA). 15,550,468 Illumina MiSeq reads were assembled de novo into 34,066 chili genes. We classified the expression patterns of individual genes as well as genes grouped into Biological Process ontologies and Metabolic Pathway categories using statistical criteria. For the analyses of gene groups we added the weighted expression of individual genes. This method was effective in interpreting general patterns of expression changes and increased the statistical power of the analyses. Subsets of genes were expressed only at a single time point sampled (1,278, 1,596, 1,519 and 1,583 genes at 10, 20, 40 and 60 DAA, respectively). We also estimated the variation in diversity and specialization of the transcriptome during chili pepper development. Approximately 17% of genes exhibited a significant change of expression in at least one of the intervals sampled. In contrast, significant differences in approximately 63% of the Biological Processes and 80% of the Metabolic Pathways studied were detected in at least one interval. Confirming previous reports, genes related to capsaicinoid and ascorbic acid biosynthesis were significantly upregulated at 20 DAA while those related to carotenoid biosynthesis were highly expressed in the last period of fruit maturation (40-60 DAA). Our RNA-Seq data was validated by examining the expression of nine genes involved in carotenoid biosynthesis by qRT-PCR. Conclusions In general, more profound changes in the chili fruit transcriptome were observed in the intervals between 10 to 20 and 40 to 60 DAA. The last interval, between 40 to 60 DAA, included 49% of all significant changes detected, and was characterized predominantly by a global decrease in gene expression. This period signals the end of maturation and the beginning of senescence of chili pepper fruit. The transcriptome at 60 DAA was the most specialized and least diverse of the four states sampled.

Project description:Seven different Solanaceae species, Potato (Solanum tubersosum), Tomato (Solanum lycopersicum), Eggplant (Solanum melangena), Pepper (Capsicum annuum), Tobacco (Nicotiana tabaccum), Petunia and Nicotiana benthiamana were subjected to salt stress. The stress applied was 150mM NaCl and control plants were watered without the additional salt. Samples were collected at 0, 6, 12, 24, 48 and 96 hours after the first application of the salt. RNA was isolated using Qiagen RNeasy. Keywords: Direct comparison
