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:EGCG, as an active oxygen scavenger, has a significant effect on inhibiting the greasiness of apples. However, the impact of greasiness on fruit storage and how EGCG eliminates this effect, as well as its influence on apple quality formation, have not been clarified. In this study, we found that exogenous application of EGCG effectively improved a series of nutritional growth indicators, including seedling growth status and photosynthetic activity. Additionally, it significantly increased indicators of reproductive growth, such as fruit diameter, soluble solids content, surface wax, and surface smoothness. Through our experiments, we further discovered that greasiness primarily affects fruit respiration, accelerating fruit decay and causing harm during storage, while EGCG mitigates this process. We also found that the application of tea residue had similar effects to exogenous EGCG. Collectively, these studies suggest that EGCG could be used as a novel foliar fertilizer to enhance overall fruit quality. Moreover, the application of tea residue has similar effects to EGCG, providing a cost-effective solution for apple production.

Project description:Manipulating the crop load in peach trees determines carbon supply and optimum balance between fruit yield and quality potentials. The impact of carbon supply on peach fruit quality was assessed in three development stages (S2, S3, S4) on fruit of equal maturity from trees that were carbon (C) starved (unthinned) and sufficient (thinned). Previous studies determined that primary metabolites of peach fruit mesocarp are mainly linked with developmental processes, thus, the secondary metabolite profile was assessed using non-targeted liquid chromatography mass-spectrometry (LC-MS). Carbon sufficient (C-sufficient) fruit demonstrated superior quality attributes as compared to C-starved fruit. Early metabolic shifts in the secondary metabolome appear to prime quality at harvest. Enhanced C-availability facilitated the increased and consistent synthesis of flavonoids, like catechin, epicatechin and eriodyctiol, via the phenylpropanoid pathway, providing a link between the metabolome and fruit quality, and serving as signatures of C-sufficiency during peach fruit development.

Project description:Anthocyanins, total phenols, soluble sugar and fruit shape play a significant role in determining the distinct fruit quality and customer preference. However, for the majority of fruit species, little is known about the transcriptomics and underlying regulatory networks that control the generation of overall quality during fruit growth and ripening. This study incorporated the quality-related transcriptome data from 6 ecological zones across 3 fruit development and maturity phases of Chardonnay cultivars. With the help of this dataset, we were able to build a complex regulatory network that may be used to identify important structural genes and transcription factors that control the anthocyanins, total phenols, soluble sugars and fruit shape in grapes. Overall, our findings set the groundwork to improve grape quality in addition to offering novel views on quality control during grape development and ripening.

Project description:Fruit length is a key domestication trait that affects crop yield and appearance quality. Cucumber fruits vary from 5~60 cm in length. Despite multiple fruit length QTLs have been identified, the underlying genes and regulatory mechanisms are poorly understood. Map-based cloning identified a nonsynonymous SNP (G to A) in CRABS CLAW (CsCRC) confers the major effect fruit length QTL FS5.2. CsCRCA is a rare allele only exist in Xishuangbanna cucumber with round fruits. Construction of near-isogenic line (NIL) of CsCRCA led to 34~39% reduction in fruit length. Introduction of CsCRCG into the NIL rescued the short-fruit phenotype, and knockdown of CsCRCG resulted in reduced fruit length and decreased cell size. RNA-seq results showed that an auxin responsive protein CsARP1 expressed decreased in CsCRC-RNAi lines. Further, an auxin responsive protein Further, CsARP1 is the downstream target gene of CsCRCG, instead of CsCRCA. Knockout of CsARP1 produced decreased fruit length with smaller cells. Hence, our work suggested that CsCRCG positively regulates fruit elongation through transcriptional activation of CsARP1 and thus enhanced cell expansion. Utilization of CsCRC alleles provides a new strategy to manipulate fruit length in cucumber breeding.

Project description:Five rootstock cultivars of differing vigor: vigorous (Atlas and Brights Hybrid 5), standard (Krymsk 86 and Lovell) and dwarfing (Krymsk 1) with Redhaven as scion were studied for their impact on internal fruit quality and maturity. Five years of data showed that average yield (kg per tree) and fruit count increased significantly with increasing vigor (trunk cross sectional area, TCSA), however, no difference was observed in fruit size across rootstocks. In 2019, a detailed peach fruit quality analysis on fruit of equal maturity (based on index of absorbance difference, IAD) coming from trees with equal crop load (no. of fruit cm-2 of TCSA) characterized the direct impact of rootstock vigor on peach internal quality. Twenty-five fruits from each rootstock were assessed for maturity [IAD and flesh firmness (FF)] and internal quality [dry matter content (DMC) and soluble solids concentration (SSC)]. Physiologically characterized peach fruit mesocarp was further analyzed by non-targeted metabolite profiling using gas chromatography mass spectrometry (GC-MS). To account for differences in light availability created by the varying levels of vigor, and its influence on the developing fruits internal quality, mid-canopy photosynthetic active radiation transmission (i.e., light availability) was collected across genotypes with a line quantum sensor. DMC and SSC increased significantly with decreasing vigor and increasing light availability, potentially due to reduced intra-tree shading and better light distribution within the canopy. Metabolite distribution was associated with rootstock vigor class, mid-canopy light availability and fruit quality characteristics. Fructose, glucose, sorbose, neochlorogenic and quinic acids, catechin and sorbitol were associated with high light environments and enhanced quality traits, while sucrose, butanoic and malic acids related to low light conditions and inferior fruit quality. These outcomes show that while rootstock genotype and vigor are influencing peach tree productivity and yield, their effect on manipulating the light environment within the canopy also plays a significant role in fruit quality development.

Project description:Cucumber (Cucumis sativus L.) is an important vegetable crop bearing fleshy pepo fruits that harvested immature. The fruit length is one of the most important agricultural traits that directly determine the fruit yield and affects fruit quality, but the regulatory mechanism of fruit length variation remains elusive. Here we found a FRUITFULL-like MADS-box gene CsFUL1 functions as a key repressor for fruit length regulation in cucumber. The expression of CsFUL1 is highly enriched in male flowers and fruits, and negatively correlated with fruit length in different cucumber lines. Notably, a key SNP in CsFUL1 was selected during cucumber domestication for long fruit. Ectopic expression of CsFUL1 was unable to rescue the indehiscent fruit phenotype of ful-1 in Arabidopsis. Overexpression of CsFUL1 resulted in increased floral organs and reduced fruit length, whereas knockdown of CsFUL1 led to elongated fruit in cucumber. Transcriptome and biochemical analyses showed that CsFUL1 regulates fruit length through two pathways: one by inhibiting the PIN-FORWED (PIN1/7)-mediated auxin transport and thus downregulates auxin related genes in the fruit, and the other by forming a tetramer with other MADS-box genes to repress the CsSUP-mediated cell division and cell expansion. In addition, we found that CsFUL1 promotes locule number variation through the classical CsWUS-CsCLV pathway. Our findings uncover the regulatory commonality and specificity during development of different fruit types, and provide an important candidate gene to customize fruit length during cucumber breeding.

Project description:The environmental conditions greatly influence tomato fruit quality, by affecting the expression of genes, the abundance of metabolites and the perception of sensorial attributes.In this study, a fruit transcriptome investigation, together with a sensory test and a metabolomic analysis were per-formed to evaluate the impact of the environment on two popular tomato cultivars grown in two Italian regions. The transcriptional profile of each cultivar, cultivated in two different areas high-lighted differential expression in genes involved in pathways related to cell wall components such as pectin, lignin and hemicellulose, sugars as well as in amino acids, phenylpropanoids, and pigment synthesis. The cultivation area mainly affects sensory attributes related to texture and flavor and the metabolic pattern of cell wall precursors, sugars, glutamate, aspartate and carotenoids. In the two genotypes cultivated in the same environment, some attributes and fruit-related quality processes are similarly affected, while others are differently influenced based on tomato specific genetic makeup. Combination of transcriptomic, sensory and metabolomic data obtained from the two tomato genotypes revealed that the environment has a profound effect on specific sensory traits, providing information on factors that shape the specific characteristics and genetic targets for im-proving tomato fruit characteristics.
