Transcriptional profiling of calyx abscission zone cells of citrus fruits and adjacent fruit rind cells during ethylene-promoted fruit abscission

ABSTRACT: Abscission is a cell separation process that takes place in particular positions of the plant body named abscission zones. In citrus, maturing fruits are shed through the calix abscission zone, which is composed by 10-15 cell layers located at the boundary between the calyx button and the fruit rind. In order to gain further insight into the molecular mechanisms involved in citrus fruit abscission, we used laser microdissection combined with microarray analysis to compare the global expression profiles of calyx abscission zone cells and adjacent fruit rind cells (control cells) at 0, 12 and 24 hours after the activation of the process with ethylene. Thus, this study allowed identifying a set of abscission zone-specifically expressed genes potentially involved in citrus fruit abscission.

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.

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

Project description: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.

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.

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.
