Effect of allelic variation at the Glu-3 / Gli-1 loci on breadmaking quality parameters in hexaploid wheat [Triticum aestivum L.]
Bonafede, Marcos; Tranquilli, Gabriela; Pfluger, Laura Alicia; Peña, Roberto Javier; Dubcovsky, Jorge (2015-03)Low molecular weight glutenin subunits (LMW-GS) encoded by the Glu-3 loci are known to contribute to wheat breadmaking quality. However, the specific effect of individual Glu-3 alleles is not well understood due to their ... -
Effect of the Hope FT-B1 Allele on wheat heading time and yield components
Nitcher, Rebecca; Pearce, Stephen; Tranquilli, Gabriela; Xiaoqin, Zhang; Dubcovsky, Jorge (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. ... -
Mapping a region within the 1RS.1BL translocation in common wheat affecting grain yield and canopy water status
Howell, Tyson; Hale, Iago; Jankuloski, Ljupcho; Bonafede, Marcos; Gilbert, Matthew; Dubcovsky, Jorge (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
Cobo, Nicolás; Pfluger, Laura Alicia; Chen, Xianming; Dubcovsky, Jorge (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 ... -
Regulation of Zn and Fe transporters by the GPC1gene during early wheat monocarpic senescence
Pearce, Stephen; Tabbita, Facundo; Cantu, Dario; Buffalo, Vince; Avni, Raz; Vazquez Gross, Hans; Zhao, Rongrong; Conley, Christopher J.; Distelfeld, Assaf; Dubcovsky, Jorge (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
Lewis, Silvina; Faricelli, M.E.; Appendino, M.L.; Valárik, M.; Dubcovsky, Jorge (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
VanGessel, Carl; Hamilton, James; Tabbita, Facundo; Dubcovsky, Jorge; Pearce, Sthepen (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)
Zhang, Junli; LI, Chengxia; Zhang, Wenjun; Zhang, Xiaoqin; Mo, Youngjun; Tranquilli, Gabriela; Vanzetti, Leonardo Sebastian; Dubcovsky, Jorge (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 ...
