Modern commercial tomato varieties are substantially less flavorful than heirloom varieties. To understand and ultimately correct this deficiency, we quantified flavor-associated chemicals in 398 modern, heirloom, wild accessions. A subset of these accessions was evaluated consumer panels, identifying the that made most important contributions to flavor liking. We found modern contain significantly lower amounts many older Whole-genome sequencing a genome-wide association study permitted...
Saffron, the processed stigma of <i>Crocus sativus</i>, is characterized by presence several apocarotenoids that contribute to color, flavor, and aroma spice. However, little known about synthesis compounds during development <i>C. sativus</i> stigma. The developing nearly odorless, but before at anthesis, aromatic compound β-ionone becomes principal norisoprenoid volatile in In this study, four carotenoid cleavage dioxygenase (CCD) genes, <i>CsCCD1a</i>, <i>CsCCD1b</i>, <i>CsCCD4a</i>,...
Abstract Improvement of strawberry (Fragaria × ananassa) fruit flavor is an important goal in breeding programs. To investigate genetic factors controlling this complex trait, a mapping population derived from genotype ‘1392’, selected for its superior flavor, and ‘232’ was profiled volatile compounds over 4 years by headspace solid phase microextraction coupled to gas chromatography mass spectrometry. More than 300 were detected, which 87 identified comparison spectrum retention time those...
The volatile composition of fruit from four Citrus varieties (Powell Navel orange, Clemenules mandarine, and Fortune mandarine Chandler pummelo) covering different species has been studied. Over one hundred compounds were profiled after HS-SPME-GC-MS analysis, including 27 esters, 23 aldehydes, 21 alcohols, 13 monoterpene hydrocarbons, 10 ketones, 5 sesquiterpene 4 cyclic ethers, furans, 2 aromatic which all confirmed with standards. differences in the profile among juices these essentially...
Phenylpropanoid volatiles are responsible for the key tomato fruit (Solanum lycopersicum) aroma attribute termed "smoky." Release of these from their glycosylated precursors, rather than biosynthesis, is major determinant smoky in cultivated tomato. using a combinatorial omics approach, we identified non-smoky glycosyltransferase1 (NSGT1) gene. Expression NSGT1 induced during ripening, and encoded enzyme converts cleavable diglycosides smoky-related phenylpropanoid into noncleavable...
Abstract Low temperature is a major environmental stress that seriously compromises plant development, distribution and productivity. Most crops are from tropical origin and, consequently, chilling sensitive. Interestingly, however, some plants, able to augment their tolerance when previously exposed suboptimal growth temperatures. Yet, the molecular physiological mechanisms underlying this adaptive process, termed acclimation, still remain practically unknown. Here, we demonstrate tomato...
Abstract Plants are frequently subjected to different combinations of abiotic stresses, such as high light (HL) intensity, and elevated temperatures. These environmental conditions pose a threat agriculture production, affecting photosynthesis, decreasing yield. Metabolic responses plants, alterations in carbohydrates amino acid fluxes, play key role the successful acclimation plants directing resources toward stress responses, suppressing growth. Here we show that primary metabolic response...
Mediterranean basin and other citrus-growing areas, such as Florida or California, are among the most vulnerable regions to impacts of global warming. Therefore, citrus will be likely subjected increasing periods water scarcity combined with high temperatures that impair plant growth, development yield. In industry, grafting is used improve varietal characteristics, abiotic stress tolerance. Previous research showed under drought heat conditions, Carrizo citrange (Poncirus trifoliata ×...
Numerous studies have revealed the extent of genetic and phenotypic variation between both species cultivars tomato. Using a series tomato lines resulting from crosses cherry three independent large fruit cultivar (Levovil, VilB, VilD), extensive profiling central primary metabolism volatile organic components was performed. In this study, it possible to define number quantitative trait loci (QTLs) which determined levels metabolites and/or evaluate their co-location with previously defined...
Abstract Virus-induced gene silencing (VIGS) is a powerful tool for reverse genetics in tomato (Solanum lycopersicum). However, the irregular distribution of effects VIGS hampers identification and quantification nonvisual phenotypes. To overcome this limitation, visually traceable system was developed fruit, comprising two elements: (1) transgenic line (Del/Ros1) expressing Antirrhinum majus Delila Rosea1 transcription factors under control fruit-specific E8 promoter, showing...
Polyamine oxidases (PAOs) are flavin-dependent enzymes involved in polyamine catabolism. In Arabidopsis five PAO genes (AtPAO1-AtPAO5) have been identified which present some common characteristics, but also important differences primary structure, substrate specificity, subcellular localization, and tissue-specific expression pattern, may suggest distinct physiological roles. the work, AtPAO5, only so far uncharacterized AtPAO is specifically expressed vascular system, was partially...
Volatile organic compounds (VOCs) are major determinants of fruit flavor, a primary objective in tomato breeding. A recombinant inbred line (RIL) population consisting 169 lines derived from cross between Solanum lycopersicum and red-fruited wild species pimpinellifolium accession (SP) was characterized for VOCs three different seasons. Correlation hierarchical cluster analyses were performed on the 52 identified, providing tool putative assignation individual to metabolic pathways....
Soil flooding is a compound abiotic stress that alters soil properties and limits atmospheric gas diffusion (O 2 CO ) to the roots. The involvement of abscisic acid (ABA) in regulation flooding-specific genetic metabolic responses has been scarcely studied despite its key importance as regulator other conditions. To attain this objective, wild type ABA-deficient tomatoes were subjected short-term (24 h) waterlogging. After period, exchange parameters reduced but not plants always had higher...
Crocins and picrocrocin are high-value hydrophilic pigments produced in saffron used commercially the food pharmaceutical industries.
