Genetic mapping and QTL analysis for peanut smut resistance
(BioMed Central, 2021-07)
Background: Peanut smut is a disease caused by the fungus Thecaphora frezii Carranza & Lindquist to which most commercial cultivars in South America are highly susceptible. It is responsible for severely decreased yield ...
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 ...
Chromosomal loci important for cotyledon opening under UV-B in Arabidopsis thaliana
(BioMed Central, 2010-06)
Background: Understanding of the genetic architecture of plant UV-B responses allows extensive targeted testing of candidate genes or regions, along with combinations of those genes, for placement in metabolic or signal ...
Dissecting the genetic control of root and leaf tissue-specific anthocyanin pigmentation in carrot (Daucus carota L.)
(Springer, 2019-05)
Purple carrots can accumulate large quantities of anthocyanins in their root tissues, as well as in other plant parts. This work investigated the genetic control underlying tissue-specific anthocyanin pigmentation in the ...
Mapping QTL for spike fertility and related traits in two doubled haploid wheat (Triticum aestivum L.) populations
(BMC, 2021-07)
Background: In breeding programs, the selection of cultivars with the highest yield potential consisted in the selection of the yield per se, which resulted in cultivars with higher grains per spike (GN) and occasionally ...
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 regulation ...
Phenotyping and QTL mapping for cold tolerance at the germination and seedling stages in Argentine temperate rice
(Springer, 2020-07)
In Argentina, the yield potential of rice (Oryza sativa L.) under suboptimal temperatures of temperate regions and during early sowing in tropical regions depends on its low-temperature germinability (LTG) and subsequent ...
Reduced nighttime transpiration is a relevant breeding target for high water-use efficiency in grapevine
(National Academy of Sciences, 2016-08)
Increasing water scarcity challenges crop sustainability in many regions. As a consequence, the enhancement of transpiration efficiency (TE)-that is, the biomass produced per unit of water transpired-has become crucial in ...
Phenomics allows identification of genomic regions affecting maize stomatal conductance with conditional effects of water deficit and evaporative demand
(Wiley Blackwell Publishing, Inc, 2018-02)
Stomatal conductance is central for the trades-off between hydraulics and photosynthesis. We aimed at deciphering its genetic control and that of its responses to evaporative demand and water deficit, a nearly impossible ...
