Genome-Wide Transcription During Early Wheat Meiosis Is Independent of Synapsis, Ploidy Level, and the Ph1 Locus.
Polyploidization is a fundamental process in plant evolution. One of the biggest challenges faced by a new polyploid is meiosis, particularly discriminating between multiple related chromosomes so that only homologous chromosomes synapse and recombine to ensure regular chromosome segregation and balanced gametes. Despite its large genome size, high DNA repetitive content and similarity between homoeologous […]
Despite wheat being a worldwide staple, no genetically modified (GM) wheat has been deployed. Here we analyse the socio-economic reasons why wheat has become a “GM orphan crop”, and discuss how technical advances in the discovery and cloning of resistance genes could be used to engineer resistance against major diseases causing widespread destruction in South […]
DFW researchers from JIC collaborated with researchers in the University of Queensland and The Plant Breeding Institute, Australia to develop protocols for rapid generation advancement, dubbed ‘speed breeding’. By manipulating the light regime, we were able to achieve significantly accelerated generation times (at least twice as fast) for a large range of crop plants (wheat, barley, […]
Wheat receptor-kinase-like protein Stb6 controls gene-for-gene resistance to fungal pathogen Zymoseptoria tritici
In this collaborative study between DFW researchers at RRes and JIC, and those from INRA in France the first wheat gene conferring resistance to a devastating foliar disease of wheat known as Septoria tritici blotch (STB) has been isolated. Most resistance genes in wheat, other monocots and also dicots code for protein NB-LRR receptors located […]
