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...
Tomato near-isogenic lines differing in fruit carotenogenesis genes accumulated different aroma volatiles, a strikingly similar fashion as compared to watermelon cultivars color. The major volatile norisoprenoids present lycopene-containing tomatoes and watermelons were noncyclic, such geranial, neral, 6-methyl-5-hepten-2-one, 2,6-dimethylhept-5-1-al, 2,3-epoxygeranial, (E,E)-pseudoionone, geranyl acetone, farnesyl seemingly derived from lycopene other noncyclic tetraterpenoids. β-Ionone,...
Abstract Phenotypes of the tomato (Solanum lycopersicum) high pigment-2dg (hp-2dg) and hp-2j mutants are caused by lesions in gene encoding DEETIOLATED1, a negative regulator light signaling. Homozygous hp-2dg plants display plethora distinctive developmental metabolic phenotypes comparison to their normal isogenic counterparts. These are, however, best known for increased levels carotenoids, primarily lycopene, other plastid-accumulating functional metabolites. In this study we analyzed...
Pomegranate peel is a nutritive-rich byproduct whose amounts are extensively growing due to the exponential increase in production of pomegranate juice and "ready eat" arils. rich source for antioxidants thus may serve prevention cattle diseases improvement beef products, making it an attractive component diets. The present study aims evaluate effect commonly used storage practices on nutritive antioxidative properties peel. In general, conditions preserved most antioxidant capacity....
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...
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...
Cucumis melo is highly diverse for fruit traits providing wide breeding and genetic research opportunities, including genome-wide association (GWA) analysis. We used a collection of 177 accessions representing the two C. subspecies 11 horticultural groups detailed characterization variation evaluation potential GWA trait mapping in melon. Through genotyping-by-sequencing, 23,931 informative SNPs were selected analyses. found that linkage-disequilibrium decays at ~100 Kb this population...
The tomato Anthocyanin fruit (Aft) genotype is characterized by purple color in skin and outer pericarp of its fruits due to higher levels anthocyanins—flavonoid metabolites. Our objectives were carry out metabolic molecular characterization this genotype, emphasizing interaction with the high pigment-1 (hp-1) mutation, known increase flavonoids fruits. These fit growing interest developing functional results show that 1) Aft are also significantly flavonols quercetin kaempferol, thus...
Melon fruit flesh color is primarily controlled by the "golden" single nucleotide polymorhism of "Orange" gene, CmOr, which dominantly triggers accumulation pro-vitamin A molecule, β-carotene, in mesocarp. The mechanism CmOr operates not fully understood. To identify cellular and metabolic processes associated with allelic variation, we compared transcriptome bulks developing homozygous orange green fruited F3 families derived from a cross between parental lines. Pooling together that share...
Although light is the driving force of photosynthesis, excessive can be harmful. One main processes that limits photosynthesis photoinhibition, process light-induced photodamage. When absorbed exceeds amount dissipated by photosynthetic electron flow and other processes, damaging radicals are formed mostly inactivate photosystem II (PSII). Damaged PSII must replaced a newly repaired complex in order to preserve full activity. Chlorella ohadii green microalga, isolated from biological desert...
SUMMARY While light is the driving force of photosynthesis, excessive can be harmful. Photoinhibition one key processes that limit photosynthetic productivity. A well‐defined mechanism protects from photoinhibition has been described. Chlorella ohadii a green micro‐alga, isolated biological desert soil crusts, which thrives under extreme high (HL). Here, we show this alga evolved unique protection mechanisms distinct those Chlamydomonas reinhardtii or plants. When grown HL, drastic reduction...
Fruit constitutes a major component of our diet, providing fiber, vitamins, minerals, and many phytonutrients that promote good health. Fleshy fruits such as tomatoes already contain high levels several these ingredients. Nevertheless, efforts have been invested in increasing diversifying the content phytonutrients, carotenoids flavonoids, tomato fruits. These rely on transgenic approaches, use single-point mutations and/or quantitative trait loci affecting phytonutrients. The pigment (hp)...
Carotenoids are isoprenoid pigments that upon oxidative cleavage lead to the production of norisoprenoids have profound effect on flavor and aromas agricultural products. The biosynthetic pathway in carrots (Daucus carota L.) is still largely unknown. We found volatile farnesylacetone, α-ionone, β-ionone accumulated Nairobi, Rothild, Purple Haze cultivars but not Yellowstone Creme de Lite a pattern reflecting their carotenoid content. A cDNA encoding protein with dioxygenase activity,...
