Expression data from postharvest Ponkan (Citrus reticulata Blanco) fruit under cold storage

ABSTRACT: Low temperature storage of citrus fruits are susceptible to chilling disorder symptoms that impact fruit quality. Understanding the molecular frame underlying the cold storage process will provide a basic guidance for practical control. We used Affymetrix Citrus GeneChip to examine the transcriptional changes in cold-stored Citrus reticulata Blanco cv. âPonkanâ pulp tissue for three successive months. Ponkan postharvest fruits were under cold storage for three successive months. The pulp tissue was used for RNA extraction and hybridization on Affymetrix Citrus Genome microarrays.

Expression data from Senescence Process of citrus

Project description:The postharvest senescence processes of citrus fruits were analyzed transcriptomic. The present study was aimed to: further uncover the rind-flesh communication of hesperidium; characterize the differential storage behaviors of different citrus varieties; reveal the important changes during storing process; and demonstrate the specific non-climacteric characteristics of citrus fruits. We chose four major table fruit varieties of citrus: satsuma mandarin (Citrus unshiu Marc) (M), ponkan (Citrus reticulata Blanco) (K), newhall navel orange (Citrus sinensis L. Osbeck) (O) and shatian pummelo (Citrus grandis Osbeck) (P). They were sampled every 10 days during 50 DAH (days after harvest), almost covering the commercial storage period of loose-skin citrus.

The differential expression analysis of young and ripe kumquat fruits with microarray

Project description:Kumquat (Fortunella classifolia Swingle) was thought as a close relative to citrus according to fruit morphology taxonomic, but kumquat fruit as well as its flowering characteristic are distinct from other citrus species, the trees usually blooms on the medium of June, obviously later than other citrus species, moreover many kumquat accessions could be blossom more than one times during one growth season, as this reason, the kumquat fruits could be consecutively ripen over several months, which made the study of globe genes expression profile for different development stage fruit easy. Kumquat is non-climacteric fruit, however the kumquat fruit ripening process, especially genes expression change in young and ripe kumquat fruits are less known, so studying on the global genes expression profiles of kumquat fruits in young and ripe stage are especially helpful to identify ripening-related genes and unravel the mechanism of ripening process.

Transcriptomic profiling reveals Neofabraea vagabunda infection-induced changes in susceptible and resistant apples during storage

Project description:Bull’s eye rot is one of the most severe diseases that may affect apples during storage. It is caused by the fungus Neofabraea vagabunda, and the mechanism by which the pathogen infects the fruits is only partially understood. In particular, very little is known about the molecular mechanisms regulating the interaction between the pathogen and the host during symptoms development. Despite different apple cultivars show different levels of resistance to the pathogen, the genetic basis of these responses are unknown. In order to understand the molecular mechanisms occurring in the apple fruit during N. vagabunda infection, a large-scale transcriptome study by RNA-Seq analysis was performed, comparing fruits of the sensitive ‘Roho’ cultivar and the resistant cultivar ‘Ariane’ after artificial infection with N. vagabunda and a storage period of 4 months.

Comparative gene expression profiles on contrasting mealy phenotypes in peach fruits reveal candidate genes associated with fruit quality

Project description:Storage at low temperatures is one of the most used methods to prolong the life of postharvest peaches (Prunus persica (L) Batch.). However, fruit quality is adversely affected by the development of woolliness, a physiological disorder that is apparent when the fruit is ripened after prolonged periods of cold storage and is mainly manifested as loss of juice in the peaches. The aim of this study was to obtain a more detailed cohort of genes that underlie the wolliness in a segregating population with contrasting phenotypes of mealiness after being exposed to cold storage at 4 °C. For this, a transcriptomics approach was applied to fruits from a progeny of individuals accounted for 6% more juicy and woolly 6% over a 2 years. Our results suggest that not only genes related to the maintenance of cell wall architecture may contribute to the development of mealy phenotype. Based on its possible physiological process and differential pattern of expression transcriptomic profiles show that genes related to maintenance (modification I) and membrane fluidity account for the differences between fruits that exhibit contrasting phenotypes of mealiness. These genes may contribute to tolerance to cold during storage. We analyzed a total of 9 woolly fruits (from 3 different trees, 3 fruits from each tree) and 12 juicy fruits (from 4 different trees, 3 fruits from each tree). An RNA pool from 9 woolly fruits was used as reference and was compared to an RNA pool of 3 juicy fruits from each individual tree. Two technical replicates were done for each comparison, thus making in total 8 hybridizations.

Large scale analysis of apple mealiness within IM apple progeny

Project description:Based on sensorial analysis over 4 years, 6 apple genotypes with contrasted fruit texture (mealy or not) were selected among a progeny. Apple samples were collected at 100 days after flowering (100 DAF), harvest (H), after 2 and 4 months of cold storage (60DAH and 120DAH respectively). 6 apple hybrids were analysed in dye-switch. Biological replicates are fruits from 2 to 4 different harvest years. Each mealy hybrid was compared to a non-mealy hybrid from the same harvest year in 12 dye-swap 3 pairs at 4 four time points).

A genomic approach to bud mutation in sweet orange (Citrus sinensis L. Osbeck) fruit

Project description:Bud mutations arise often in citrus. The selection of mutants is one of the most important breeding methods in citrus. However, the molecular bases of bud mutation have rarely been studied. To identify the potential important or novel genes involved in bud mutation, different transcriptomic techniques combing suppression subtractive hybridization (SSH) and microarray were performed between a lycopene accumulated mutant, âHong Anliuâ sweet orange (Citrus sinensis L. Osbeck), and its wild-type during fruit maturation. Microarray analysis revealed that differentially expressed clones are extensively coordinated with the initiation of lycopene accumulation. After sequencing of the differentially expressed clones, a total of 267 non-redundant transcripts were obtained, 182 (68.2%) of which share homology (E-value â¤ 1Ã10-10) with known gene products or known protein domains. A list of candidate genes which involved in cellular metabolic process, primary metabolic process, localization, macromolecular metabolic process was obtained. Out of these genes, 12 share homology with previously described signal transduction or transcription factors, suggesting complex regulatory control. These results demonstrate profound effect on gene expression of bud mutation in citrus fruits and provide new insights into the molecular basis of bud mutation. Keywords: bud mutation, candidate genes, Citrus, cNDA microarray, suppression subtractive hybridization (SSH) Fruits from the mutant and its wild type were collected at five time points from August to December. Total RNA extracted from the mutant was hybridized to the array together with RNA from the wild type. Each hybridization was performed in duplicate by dye swap.
