A genome-wide association study unveils key chromosome regions involved in determining sodium accumulation in wheat under conditions of low potassium supply
(Elsevier, 2022-05-30)Improving nutrient use efficiency is an important objective in modern breeding programs. In this work, we examined potassium utilization efficiency (KUtE) and traits potentially related to it in a formerly genotyped, ... -
Allelic variation of puroindolines genes in Iranian common wheat landraces
(MDPI, 2022-08-10)Wheat is one of the most widely grown crops in the world. One of the traits that defines wheat quality is grain hardness, which is determined by puroindolines (PINA and PINB) proteins encoded with Pina-D1 and Pinb-D1 genes. ... -
Characterization of the repetitive DNA landscape in wheat homeologous group 4 chromosomes
(2015)Background: The number and complexity of repetitive elements varies between species, being in general most represented in those with larger genomes. Combining the flow-sorted chromosome arms approach to genome analysis ... -
Effect of the Hope FT-B1 Allele on wheat heading time and yield components
(2014-09)Precise regulation of flowering time is critical for plant reproductive success and, in cereals, to maximize grain yields. Seasonal cues including temperature and day length are integrated to regulate the timing of flowering. ... -
Genetic and physical mapping of the earliness perse locus Eps - Am1 in Triticum monococcum identifies early flowering 3 (ELF3) as a candidate gene
(2016-07)Wheat cultivars exposed to optimal photoperiod and vernalization treatments still exhibit differences in heading time. This variation, known as earliness per se (Eps), is important for the fine-tuning of flowering and the ... -
Grain mineral composition of Argentinean-adapted wheat cultivars: a case study
(CSIRO, 2021-02-23)Abstract. Improvement of the nutritional quality of wheat (Triticum aestivum L.) has been quite challenging, due, in part, to the limited variation found in modern cultivars and the strong effect exerted by the environment, ... -
How does post-flowering sources/sink manipulation affect grain weight and commercial quality in Argentinean bread wheat genotypes with different baking aptitude?
(Elsevier, 2023-06-29)Context: Wheat is a crop of vital importance for food security. In contrast to the accumulated knowledge for yield determination, the effect of variations in the source/sink (S/S) ratio on grain quality, and its interaction ... -
Impact of different on-farm management practices on breat wheat quality: a case study in the Yaqui Valley
(Wiley, 2023-08-15)Continuous development of new wheat varieties is necessary to satisfy the demands of farmers, industry, and consumers. The evaluation of candidate genotypes for commercial release under different on-farm conditions is a ... -
Mapping a region within the 1RS.1BL translocation in common wheat affecting grain yield and canopy water status
(Springer, 2014-12)The translocation of the short arm of rye (Secale cereale L.) chromosome one (1RS) onto wheat (Triticum aestivum L.) chromosome 1B (1RS.1BL) is used in wheat breeding programs worldwide due to its positive effect on yield, ... -
Mapping QTL for resistance to new virulent races of wheat stripe rust from two Argentinean wheat cultivars
(Crop Science Society of America, 2018)During the last two decades, new virulent and aggressive races of Puccinia striiformis Westend. f. sp. tritici (Pst) have spread worldwide, causing devastating epidemics and prompting the search for new sources of resistance ... -
Nitrogen–sulfur fertilisation effects on gluten composition and industrial quality in Argentinean bread wheat cultivars differing in apparent sulfur recovery
(CSIRO, 2021-03-12)Increasing wheat yield and grain quality is crucial for achieving profitable production systems. Genotype has an important role in determining potential grain end-use quality, because it defines the protein subunits stored ... -
On-farm assessment of yield and quality traits in durum wheat
(Wiley, 2023-08-15)Durum wheat is key source of calories and nutrients for many regions of the world. Demand for it is predicted toincrease. Further efforts are therefore needed to develop new cultivars adapted to different future scenarios. ... -
On-farm impact on bread wheat quality under different management practices: a case study in the Yaqui Valley
(Wiley, 2023-03-24)Continuous development of new wheat varieties is necessary to satisfy the demands of farmers, industry, and consumers. The evaluation of candidate genotypes for commercial release under different on-farm conditions is a ... -
Regulation of Zn and Fe transporters by the GPC1gene during early wheat monocarpic senescence
(2014-12)Background; During wheat senescence, leaf components are degraded in a coordinated manner, releasing amino acids and micronutrients which are subsequently transported to the developing grain. We have previously shown that ... -
The chromosome region including the earliness per se locus Eps-Am1 affects the duration of early developmental phases and spikelet number in diploid wheat
(Society for Experimental Biology, 2008-10)Earliness per se genes are those that regulate flowering time independently of vernalization and photoperiod, and are important for the fine tuning of flowering time and for the wide adaptation of wheat to different ... -
Transcriptional signatures of wheat inforescence development
(Springer Nature, 2022-10-14)In order to maintain global food security, it will be necessary to increase yields of the cereal crops that provide most of the calories and protein for the world’s population, which includes common wheat (Triticum aestivum ... -
Wheat plant height locus RHT25 encodes a PLATZ transcription factor that interacts with DELLA (RHT1)
(National Academy of Sciences, 2023-05-01)Plant height is an important agronomic trait with a significant impact on grain yield, as demonstrated by the positive effect of the REDUCED HEIGHT (RHT) dwarfing alleles (Rht1b) on lodging and harvest index in the “Green ...
