Combining QTL mapping and gene expression analysis to elucidate the genetic control of ‘crumbly’ fruit in red raspberry

ABSTRACT: ‘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.

Transcriptomic profiling of fruits of four raspberry cultivars with different pigmentation

Project description:The developing fruit harvested at three developmental stages, ‘unripe’, ‘turning’ and ‘mature’ from the four raspberry cultivars investigated, ‘Anitra’, Glen Ample’ and ‘Veten’ and ‘Varnes’ were used for gene expression analysis. The fruit of ‘Varnes’ shows a clear lack of red pigmentation at the ‘turning’ and ‘mature’ stages, with fruit displaying a yellow colour in the ‘unripe’ and ‘turning’ stages, turning apricot in colour when fully mature, in contrast to the red colouration of the other three cultivars. A total of 36 RNA libraries (four cultivars × three fruit developmental stages × three biological replicates) were paired-end sequenced.

Examining the genes and enzymes responsible for flavonoid level modification during fruit maturation in Chinese raspberry “Rubus chingii Hu”

Project description:Rubus chingii Hu, indigenous to China, is very rich in flavonoids. With the exception of anthocyanin, fruit flavonoids were much higher than most berries including other raspberry species, which partly contributed to its high phenolics and antioxidant capability. In contrast to other raspberries, anthocyanin and other flavonoids decreased as fruit matured. We investigated four typical phases of fruit maturation using transcriptomics, proteomics and metabolomics. The results indicate that the down-regulation of phenylpropanoid, flavonoid and anthocyanin biosynthesis are responsible for the metabolic decrease. The down-regulation of RcCHS (CL6140.Contig5) and RcCHI (Unigene14858 and Unigene22344) at gene and protein levels were associated with decreases of naringenin/naringenin chalcone respectively. Down-regulation of RcLAR (CL9527.Contig3) at gene and protein levels was consistent with decreases of afzelechin/epiafzelechin, catechin/epicatechin, and gallocatechin/epigallocatechin. However, multiple genes/proteins involved in the enzymatic pathways were divergent and differently regulated, e.g. Rc4CL genes/proteins were down-regulated while Rc4CL-like was maintained at constantly low levels.

Heat-induced proteomes in tomato pollen mother cells

Project description:Tomato pollen production and viability is highly vulnerable to higher temperature. Hot summers with temperature reaching above 32°C can disrupt production of viable pollens and fruit set, resulting in yield loss. In recent years, temperature above 35-38oC has become a norm during mid-summer with potential adverse impacts on the production of tomatoes and many other crop species. Pollens are developed through the microsporogenesis and micro-gametogenesis stages. The most heat sensitive period is from the meiotic process of the microsporocytes, at the young microspore stage (uninucleate stage of microspore) to during late pollen development (pollen mitosis). This project studied the heat-induced proteomes in microsporocyte, also called pollen mother cells (PMC). Homogenous PMC samples were collected from cross-sectioned frozen fresh anther tissues of tomato ‘Maxifort’ using laser capture microdissection (LCM). Tandem mass tag (TMT) proteomics analysis was conducted to identify proteomics changes related to heat tolerance during pollen development.

Transcription profiling of human oral lesions treated with bioadhesive black rasberry gel to determine the effect on gene expression and proinflammatory proteins

Project description:This portion of the study evaluated the effects of topical 10% black raspberry gel application on gene expression profiles of premalignant oral lesions. Topical application of the bioadhesive black rasberry gel was observed to modulate gene expression and reduce proinflammatory proteins in human premalignant oral lesions. Experiment Overall Design: Each patient served as their own internal control. A pretreatment specimen of the premalignant lesion was obtained for baseline parameters. Following six weeks of treatment, the treated lesional tissue was removed. All tissue samples were immediately placed in RNA later and placed in a -80 degree freezer until sample preparation.
