Special Issue Information
Dear Colleagues,
Wheat can grow in a wide range of climates and soil conditions and remains an important cereal crop around the globe. Extensive breeding efforts have gone into wheat improvement over the years, during the late twentieth and early twenty-first centuries, leading to the development of a large number of high-yielding cultivars with improved grain quality. It has also been subjected to enormous cytogenetic studies during the last century and extensive genetic and molecular studies over the past few decades. Thanks to recent genomic and technological advances, the complex wheat genome has now been sequenced along with the genomes and transcriptomes of many wheat cultivars. Moreover, intense analyses of different genes/gene families have also greatly improved our knowledge about their molecular functions and phenotypic effects in wheat. However, despite these strides, challenges persist, with diseases, pests, and abiotic stresses continuing to impact wheat production, amounting to billions of dollars per year in losses. Further increase in yield and better quality of wheat can be achieved through the improvement of resistance to different biotic and abiotic stresses. Improving our understanding of the resistance mechanisms, genetic variation, and resources available for breeding wheat can facilitate the development of superior wheat cultivars and management strategies for different stresses.
