A high-density genetic map of hexaploid wheat (Triticum aestivum L.) from the cross Chinese Spring × SQ1 and its use to compare QTLs for grain yield across a range of environments
TLDR
A population of 96 doubled haploid lines (DHLs) was prepared from F1 plants of the hexaploid wheat cross Chinese Spring × SQ1 and was mapped with 567 RFLP, AFLP, SSR, morphological and biochemical markers covering all 21 chromosomes, which confirmed the group-7 effects on yield and identified two additional major yield QTLs on chromosomes 1D and 5A.
Identification of QTLs for resistance to Fusarium head blight, DON accumulation and associated traits in the winter wheat variety Arina
TLDR
It is concluded that the FHB resistance of Arina, like that of the other European winter wheat varieties studied to date, is conferred by several genes of moderate effect making it difficult to exploit in marker-assisted selection breeding programmes.
Identification of QTL for drought responses in maize and their use in testing causal relationships between traits
TLDR
Comparing the coincidence of QTL for A BA content and stomatal conductance showed that xylem ABA content was more likely to have had a regulatory effect on the stomatic conductance of those plants than the whole leaf ABA Content.
Bulk segregant analysis with molecular markers and its use for improving drought resistance in maize
TLDR
Bulk segregant analysis (BSA), drought ating populations can also be grouped according to resistance, genetic maps, maize, molecular markers, phenotypic expression of a trait and tested for differ- mays.
Semi-dwarfing Rht-B1 and Rht-D1 loci of wheat differ significantly in their influence on resistance to Fusarium head blight
TLDR
The study demonstrates that the choice of semi-dwarfing gene used in plant breeding programmes may be a significant consideration where resistance to FHB is an important breeding target.
Susceptibility to Fusarium head blight is associated with the Rht-D1b semi-dwarfing allele in wheat
TLDR
It is demonstrated that lines carrying the Rht-1Db semi-dwarfing allele are compromised in resistance to initial infection while being unaffected in Resistance to spread within the spike (type II resistance).
Fusarium graminearum exploits ethylene signalling to colonize dicotyledonous and monocotyledonous plants.
Ethylene signalling affects the resistance of dicotyledonous plant species to diverse pathogens but almost nothing is known about the role of this pathway in monocotyledonous crop species. Fusarium
Brachypodium distachyon: a new pathosystem to study Fusarium head blight and other Fusarium diseases of wheat
TLDR
Bd is the first reported plant species to allow successful infection on intact foliar tissues by FHB-causing Fusarium species, and exhibits characteristics of susceptibility highly similar to those of wheat, including susceptibility to spread of disease in the spikelets.
Location of a gene regulating drought-induced abscisic acid production on the long arm of chromosome 5A of wheat
TLDR
The location of genes having a major effect on drought-induced ABA accumulation in wheat was determined using a set of single chromosome substitution lines and populations derived from a cross between a high-A BA- and a low-ABA-producing genotype.
Speed breeding is a powerful tool to accelerate crop research and breeding
TLDR
It is demonstrated that speed breeding in fully enclosed, controlled-environment growth chambers can accelerate plant development for research purposes, including phenotyping of adult plant traits, mutant studies and transformation.
