Project description:Two fruit development stages of the wild chiltepin pepper (Capsicum annuum var. glabriusculum) were studied. RNA-Seq data was obtained from fruits at 20 and 68 days after anthesis with two biological replicates for a total of 4 samples. 260 million raw reads were sequenced and over 80% of them mapped back to the Capsicum annuum genome.

Project description:Small RNAs (21-24 nt) are pivotal regulators of gene expression that guide both transcriptional and post-transcriptional silencing mechanisms in diverse eukaryotes, including most if not all plants. MicroRNAs (miRNAs) and short interfering RNAs (siRNAs) are the two major types, both of which have a demonstrated and important role in plant development, stress responses and pathogen resistance. In this work, we used a deep sequencing approach (Sequencing-By-Synthesis, or SBS) to develop sequence resources of small RNAs from different Capsicum annuum tissues (including leaves, flowers and fruit). The high depth of the resulting datasets enabled us to examine in detail critical small RNA features, such as size distribution, tissue-specific regulation and sequence conservation between different organs in this species. We also developed database resources and a dedicated website (http://smallrna.udel.edu/) with computational tools for allowing other users to identify new miRNAs or siRNAs involved in specific regulatory pathways, verify the degree of conservation of these sequences in other plant species and map small RNAs on genes or larger regions of the maize genome under study. Small RNA libraries were derived from leaves, flowers and fruit of Capsicum annuum. Total RNA was isolated using the TriReagent (Molecular Research Center) for leaves and flowers and the Plant RNA Purification Reagent (Invitrogen) for fruit, and submitted to Illumina (Hayward, CA, http://www.illumina.com) for small RNA library construction using approaches described in (Lu et al., 2007) with minor modifications. The small RNA libraries were sequenced with the Sequencing-By-Synthesis (SBS) technology by Illumina. PERL scripts were designed to remove the adapter sequences and determine the abundance of each distinct small RNA. We thank Barbara Baker for providing the plant material, as well as Kan Nobuta and Gayathri Mahalingam for assistance with the computational methods.

Project description:The colonization of Capsicum annuum roots by Fusarium oxysporum Fo47 induces resistance responses on the plant. Fo47 is a non-pathogenic strain of Fusarium oxysporum. Fo47 colonizes only the most outer layers of the root surface but it does not colonize inner tissues. Pre-treatment of roots with Fo47 reduces the symptom development produced by later pathogen inoculation. The expression of genes in distal tissues was determined by microarray analysis of stems of Fo47-treated plants. Capsicum annuum samples were analyzed using Affymetrix chips of the close-related species Solanum lycopersicum.

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).
