About this Research Topic
Grasses in the family Poaceae, play a key role in human life. Among them, crop grasses and forages are food for humans and livestock, respectively, while turfgrasses have been utilized by humans to improve their quality-of-life for more than ten centuries. Grasses are adapted to a wide range of ecosystems, and are environmentally compatible to different abiotic stress conditions through the development of different and complex adaptive mechanisms such as physiological, biochemical, molecular and cellular changes. Growing evidence indicates that some grasses like turfgrass are more tolerant to adverse environmental conditions than many crops. Many stress responsive genes and proteins have been identified and functionally analyzed, through ‘omics’ approaches in the grasses. Several transcription factors and functional genes that were highly induced by abiotic stress treatments, show increased plant abiotic stress tolerance in overexpression studies. Moreover, exogenous application of phytohormones like ABA and melatonin effectively increased stress tolerance in turfgrass, and small-molecule compounds including polyamine and nitric oxide also play key roles during grass stress response.
In this Research Topic we seek to build a collection of articles addressing responses of grass species to abiotic stress with the emphasis on how turfgrass and forage has adapted to adverse environmental conditions. Studies using model grasses like Brachypodium and rice are included, where they contribute to an understanding of the adaptation of turf and forage grasses to abiotic stresses. Omics related studies to elucidate transcriptomic, proteomic and metabolomics changes in grasses, and the development of genetic markers for stress tolerance traits are encouraged. The roles of phytohormones during grass stress responses will be a highlighted area. The focus is to enrich our understanding on the role of complex signaling transduction pathways in grass response and tolerance to abiotic stresses. All types of articles, including original research, review, mini review, method, perspective, and opinion are welcomed in this Research Topic.
