Quantitative trait loci and antagonistic associations for two developmentally related traits in the drosophila head
(University of Arizona, 2017-01)
In insects, some developmentally related traits are negatively correlated. Here, we mapped Quantitative Trait Loci (QTL) for traits of eye size and head capsule, in an intercontinental set of recombinant inbred lines (RILs) ...
A candidate gene survey of quantitative trait loci affecting chemical composition in tomato fruit
(Society for Experimental Biology, 2008-07)
In tomato, numerous wild-related species have been demonstrated to be untapped sources of valuable genetic variability, including pathogen-resistance genes, nutritional, and industrial quality traits. From a collection of ...
Quantitative trait loci for Fusarium and Gibberella ear rot resistance in Argentinian maize germplasm
(2016)
Fusarium verticillioides and F. graminearum cause ear rots in maize (Zea mays L.) that reduce yield and contaminate the grain with mycotoxins produced by the fungi. To map QTLs for resistance to these ear rots, a F5 mapping ...
Studying growth and vigor as quantitative traits in grapevine populations
(IntechOpen, 2019-03)
Vigor is considered as a propensity to assimilate, store, and/or use nonstructural carbohydrates for producing large canopies, and it is associated with high metabolism and fast growth. Growth involves cell expansion and ...
Maize Nitrogen Use Efficiency: QTL Mapping in a U.S. Dent x Argentine-Caribbean Flint RILs population
(2018-04)
This study was aimed to identify quantitative trait loci (QTL) for nitrogen use efficiency (NUE) and related traits in a maize population derived from a cross between two lines with different genetic background (B100 and ...
Quantitative trait loci affecting reproductive phenology in peach
(2014-02-22)
Background: The reproductive phenology of perennial plants in temperate climates is largely conditioned by the duration of bud dormancy, and fruit developmental processes. Bud dormancy release and bud break depends on the ...
Identification and validation of QTL for spike fertile floret and fruiting efficiencies in hexaploid wheat (Triticum aestivum L.)
(Springer, 2020-06)
The spike fruiting efficiency (FE—grains per unit spike dry weight at anthesis, GN/SDW) is a promising trait to improve wheat yield potential. It depends on fertile floret efficiency (fertile florets per unit SDW—FFE, ...
Genetic dissection of vitamin E biosynthesis in tomato
(Society for Experimental Biology, 2011-07)
Vegetables are critical for human health as they are a source of multiple vitamins including vitamin E (VTE). In plants, the synthesis of VTE compounds, tocopherol and tocotrienol, derives from precursors of the shikimate ...
A gene-derived SNP-based high resolution linkage map of carrot including the location of QTL conditioning root and leaf anthocyanin pigmentation
(2014-12)
Purple carrots accumulate large quantities of anthocyanins in their roots and leaves. These flavonoid pigments possess antioxidant activity and are implicated in providing health benefits. Informative, saturated linkage ...
Identification and characterization of metabolite quantitative trait loci in tomato leaves and comparison with those reported for fruits and seeds
(Springer, 2019-04)
Introduction:
To date, most studies of natural variation and metabolite quantitative trait loci (mQTL) in tomato have focused on fruit metabolism, leaving aside the identification of genomic regions involved in the ...
