The unique aroma of melons (Cucumis melo L., Cucurbitaceae) is composed many volatile compounds biosynthetically derived from fatty acids, carotenoids, amino and terpenes. Although acids are known precursors in the plant kingdom, initial steps catabolism into volatiles have received little attention. Incubation melon fruit cubes with α-keto led to enhanced formation bearing side chain exogenous or keto acid supplied. Moreover, L-[13C6]phenylalanine was also incorporated aromatic compounds....
Summary The flesh color of Cucumis melo (melon) is genetically determined, and can be white, light green or orange, with β–carotene being the predominant pigment. We associated carotenoid accumulation in melon fruit polymorphism within CmOr , a homolog cauliflower BoOr gene, identified as previously described gf locus melon. was found to co‐segregate color, presented two haplotypes (alleles) broad germplasm collection, one orange second either white flesh. Allelic variation does not affect...
The Cucurbitaceae family (cucurbit) includes several economically important crops, such as melon, cucumber, watermelon, pumpkin, squash and gourds. During the past years, genomic genetic data have been rapidly accumulated for cucurbits. To store, mine, analyze, integrate disseminate these large-scale datasets to provide a central portal cucurbit research breeding community, we developed Cucurbit Genomics Database (CuGenDB; http://cucurbitgenomics.org) using Tripal toolkit. database currently...
Sugars are key regulatory molecules that affect diverse processes in higher plants. Hexokinase is the first enzyme hexose metabolism and may be a sugar sensor mediates regulation. We present evidence hexokinase involved sensing endogenous levels of sugars photosynthetic tissues it participates regulation senescence, photosynthesis, growth seedlings as well mature Transgenic tomato plants overexpressing Arabidopsis hexokinase-encoding gene AtHXK1 were produced. Independent transgenic carrying...
The green-fruited Lycopersicon hirsutum Humb. and Bonpl. accumulated sucrose to concentrations of about 118 micromoles per gram fresh weight during the final stages development. In comparison, esculentum Mill. cultivars contained less than 15 at ripe stage. Glucose fructose levels remained relatively constant throughout development in L. 22 50 each. Starch content was low even early development, declined further with Soluble acid invertase (EC 3.2. 1.26) activity concomitant rise content....
Abstract Background A number of molecular marker linkage maps have been developed for melon ( Cucumis melo L .) over the last two decades. However, these were constructed using different sets, thus, making comparative analysis among difficult. In order to solve this problem, a consensus genetic map in was primarily highly transferable anchor markers that broad potential use mapping, synteny, and quantitative trait loci (QTL) analysis, increasing breeding effectiveness efficiency via...
Significance We identified the biosynthetic pathway for nonsugar sweetener mogroside V, a noncaloric with sweetening strength 250-fold that of sucrose. This compound is produced by fruit endemic Chinese cucurbit Siraitia grosvenoriii , also known as monk and luo-han-guo . The metabolic was using combination genomic transcriptomic databases plant, together large-scale functional expression candidate genes. novelty could be attributed to highly coordinated gene pattern responsible unique...
β-Carotene adds nutritious value and determines the color of many fruits, including melon (Cucumis melo). In mesocarp, β-carotene accumulation is governed by Orange gene (CmOr) golden single-nucleotide polymorphism (SNP) through a yet to be discovered mechanism. Arabidopsis (Arabidopsis thaliana), OR increases carotenoid levels posttranscriptionally regulating phytoene synthase (PSY). Here, we identified CmOr nonsense mutation (Cmor-lowβ) that lowered fruit with impaired chromoplast...
Combined quantitative trait loci (QTL) and expression-QTL (eQTL) mapping analysis was performed to identify genetic factors affecting melon (Cucumis melo) fruit quality, by linking genotypic, metabolic transcriptomic data from a recombinant inbred line (RIL) population. RNA sequencing (RNA-Seq) of 96 RILs yielded highly saturated collection > 58 000 single-nucleotide polymorphisms, identifying 6636 recombination events that separated the genome into 3663 genomic bins. Bin-based QTL 79 129...
Color and pigment contents are important aspects of fruit quality consumer acceptance cucurbit crops. Here, we describe the independent mapping cloning a common causative APRR2 gene regulating accumulation in melon watermelon. We initially show that transcription factor is for qualitative difference between dark light green rind both Further analyses establish link sequence or expression level variations CmAPRR2 content flesh mature fruits. A genome-wide association study (GWAS) young color...
The sugar content of Solanum lycopersicum (tomato) fruit is a primary determinant taste and quality. Cultivated tomato are characterized by near-equimolar levels the hexoses glucose fructose, derived from hydrolysis translocated sucrose. As fructose perceived as approximately twice sweet glucose, increasing its concentration at expense can improve taste. Introgressions FgrH allele wild species habrochaites (LA1777) into cultivated increased fructose-to-glucose ratio ripe reducing...
The cuticle covers the aerial epidermis of land plants and plays a primary role in water regulation protection from external stresses. Remarkable species diversity structure composition its components, cutin wax, have been catalogued, but few functional or genetic correlations emerged. Tomato (Solanum lycopersicum) is part complex closely related wild endemic to northern Andes Galapagos Islands Sect. Lycopersicon). Although sharing an ancestor <7 million years ago, these are found diverse...
Sulfur-containing aroma volatiles are important contributors to the distinctive of melon and other fruits. Melon cultivars accessions differ in content sulfur-containing volatiles. L-methionine has been postulated serve as a precursor these Incubation fruit cubes with ¹³C- ²H-labeled revealed two distinct catabolic routes into One route apparently involves action an aminotransferase preserves main carbon skeleton L-methionine. The second L-methionine-γ-lyase activity, releasing methanethiol,...
External color has profound effects on acceptability of agricultural products by consumers. Carotenoids and chlorophylls are known to be the major pigments melon (Cucumis melo L.) rinds. Flavonoids (especially chalcones anthocyanins) also prominent in other fruits but have not been reported occur melons fruit. We analyzed accumulating rinds different genotypes during fruit development. found that rind is based combinations chlorophyll, carotenoids, flavonoids according cultivar tested their...
The flavonoids are phenylpropanoid-derived metabolites that ubiquitous in plants, playing many roles growth and development. Recently, we observed fruit rinds of yellow casaba muskmelons (Cucumis melo 'Inodorous Group') accumulate naringenin chalcone, a flavonoid pigment. With RNA-sequencing analysis bulked segregants representing the tails population segregating for chalcone accumulation followed by fine mapping genetic transformation, identified Kelch domain-containing F-box protein coding...
This chapter explores the biochemical pathway of sucrose synthesis and then discusses some ideas on how is regulated by both coarse fine control. Sucrose, which major transport form reduced carbon in higher plants, either stored vacuole or exported to other parts plant. Sucrose synthase has been cloned from a number plant sources. The hydrolysis sucrose-6-P catalyzed sucrose-6-phosphate phosphatase. phenomenon sugar accumulation sinks widespread, most important agronomic crops are those that...
Cucumis melo fruit is highly valued for its sweet and refreshing flesh, however the flavour value are also influenced by aroma as dictated volatile organic compounds (VOCs). A simple robust method of sampling VOCs on polydimethylsiloxane (PDMS) has been developed. Contrasting cultivars C. subspecies were investigated at commercial maturity: three var. Cantalupensis group Charentais (cv. Cézanne, Escrito, Dalton) known to exhibit differences in ripening behaviour shelf-life, well one cultivar...
