Abiotic stress; Lipid transfer proteins; Oryza sativa L.; UBQ10

Saline stress is one of the primary factors limiting increased rice productivity in the southern region of Brazil. Farming can be affected by salinity that is due to both the origin of the soils as well as the irrigation water. Lipid transfer proteins (LTPs) have many physiological functions, including in the response to saline stress. Therefore, the objective of this study was to ... more

Cis-elements; Differential expression; Low temperature; Oryza sativa L.; Reactive oxygen species; Salinity

Different rice (Oryza sativa L.) genotypes were subjected to high salinity and low temperature (150 mM NaCl and 13°C, respectively) for 0, 6, 24, 48, or 72 h. We evaluated the simultaneous expression of the genes OsCATA, OsCATB, and OsCATC, correlated gene expression with enzyme activity, and verified the regulation of these ... more

F2:3; Flowering-related traits; Maize; MQTL; QTL; RIL

Flowering-related traits in maize are affected by complex factors and are important for the improvement of cropping systems in the maize zone. Quantitative trait loci (QTLs) detected using different materials and methods usually vary. In the present study, 266 maize (Zea mays) F2:3 families and 301 recombinant inbred lines (RIL) derived from a cross between 08-641 ( ... more

Fruit maturation period; Grape; QTL

In this study, we aimed at finding the genetic regularity of grape maturation period. Early-maturing grapevine, “87-1”, was used as the female parent and late-maturing, “9-22”, as the male parent, to create an F1 hybrid population. A total of 149 individual plants and their parents were selected as the mapping population. Sequence-related amplified polymorphism and simple-sequence repeat ... more

broiler; Candidate gene; Polymorphism; Production trait; QTL

Genetic selection for production traits has resulted in a rapid improvement in animal performance and development. Previous studies have mapped quantitative trait loci for body weight at 35 and 41 days, and drum and thigh yield, onto chicken chromosome 4. We investigated this region for single nucleotide polymorphisms and their associations with important economic traits. Three positional ... more

Nitrogen uptake and utilization efficiency; QTL; Recombinant inbred line; Rice (Oryza sativa L.)

Genetic improvement is the fundamental basis for improving nitrogen-use efficiency. A better understanding of genetic factors controlling nitrogen uptake and utilization is required for crop genetic improvement. In this study, we identified the quantitative trait loci (QTLs) associated with traits of nitrogen uptake and utilization by using the single-sequence repeat marker method and a ... more

Grape weight; Grapevine; QTL; Soluble solids

A grapevine hybrid population was derived from a crossing of the early-maturing female parent cultivar ‘87-1’ and the late-maturing male parent cultivar ‘9-22’. A total of 149 plants were selected from the hybrid population as the mapping population, and after sequence-related amplified polymorphism and simple-sequence repeat marker analysis were conducted we constructed molecular ... more
