Project description:‘Crumbly’ fruit is a developmental disorder in red raspberry (Rubus idaeus) that results in malformed fruit with poor adherence of drupelets to one another. In terms of quality and yield, crumbly fruit has become a serious problem in the raspberry industry resulting in unsaleable fruit and waste. A microarray experiment, using pools of progeny from a segregating mapping population (Glen Moy x Latham) with either 'normal' or 'crumbly' fruit at three different fruit developmental stages ('closed'; 'open'; 'green'), identified several genes that were differentially expressed between the crumbly and non-crumbly phenotypes within three quantitative trait loci (QTL) identified. Analysis of gene function highlighted the importance of processes that compromise ovule fertilization as triggers of the crumbly fruit phenotype.
Project description:We performed developmental-series analyses of the methylome to characterize integrated transcriptional, epigenetic, and metabolic reprogramming during black raspberry (Rubus occidentalis) fruit ripening.
