Several geranylgeranyl diphosphate synthase isoforms supply metabolic substrates for carotenoid biosynthesis in tomato
(Wiley, 2021-02-16)
Geranylgeranyl diphosphate (GGPP) produced by GGPP synthase (GGPPS) serves as a precursor for many plastidial isoprenoids, including carotenoids. Phytoene synthase (PSY) converts GGPP into phytoene, the ...
A novel introgression line collection to unravel the genetics of climacteric ripening and fruit quality in melon
(Nature Research, 2021-05-31)
Introgression lines are valuable germplasm for scientists and breeders, since they ease genetic studies such as QTL interactions and positional cloning as well as the introduction of favorable alleles ...
Characterization of Japanese Plum (Prunus salicina) PsMYB10 Alleles Reveals Structural Variation and Polymorphisms Correlating With Fruit Skin Color
(Frontiers Media, 2021-06-08)
The red to blue hue of plant organs is caused due to anthocyanins, which are water-soluble flavonoid pigments. The accumulation of these pigments is regulated by a complex of R2R3-MYB transcription ...
A domestication-associated gene, CsLH, encodes a phytochrome B protein that regulates hypocotyl elongation in cucumber
(Springer, 2021-06-16)
Plant height is an important agronomic trait; tall plants are prone to collapse (lodging) and are unsuitable for high-density planting (Li et al., 2020). During the Green Revolution, a multitude of genes ...
Genetic dissection of aroma biosynthesis in melon and its relationship with climacteric ripening
(Elsevier, 2021-03-05)
Aroma is an essential trait in melon fruit quality, but its complexity and genetic basis are still poorly understood. The aim of this study was the identification of quantitative trait loci (QTLs) ...
Automatic Fruit Morphology Phenome and Genetic Analysis: An Application in the Octoploid Strawberry
(American Association for the Advancement of Science, 2021-05-12)
Automatizing phenotype measurement will decisively contribute to increase plant breeding efficiency. Among phenotypes, morphological traits are relevant in many fruit breeding programs, as appearance ...
Elucidating compositional factors of maize cell walls contributing to stalk strength and lodging resistance
(Elsevier, 2021-03-19)
Lodging is one of the causes of maize (Zea mays L.) production losses worldwide and, at least, the resistance to stalk lodging has been positively correlated with stalk strength. In order to elucidate ...
Shape, firmness and fruit quality QTLs shared in two non-related strawberry populations
(Elsevier, 2021-07-29)
The cultivated strawberry (Fragaria x ananassa) is an octoploid species (2n = 8x = 56), appreciated widely for its fruit. There have been very few studies on fruit quality traits, which are known to be ...
Comparative QTL analysis in peach ‘Earlygold’ F2 and backcross progenies
(Elsevier, 2021-11-17)
Based on detailed maps, DNA sequences and phenotypic data, there is a great deal of information on the genetics and genomics of ‘Earlygold’, a historical peach cultivar from the US. The F2 between ‘Texas’ ...
