About this Research Topic
The sessile life of plants requires them to endure many challenging environments and conditions, of which drought poses one of the greatest threats. Despite continual improvements in varieties and modern agricultural management practices, drought continues to be the most serious challenge and poses a risk to agricultural production, especially in wheat, the most extensively produced crop both for humans and livestock. Therefore, the identification or development of wheat crops with better tolerance and adaptation to this abiotic stress is essential. However, the responses are complex - changes at multiple levels are combined to alter plant morphology, cell biochemistry and gene regulation. Therefore, further studies are required for wheat to address this environmental threat.
The goal of this Research Topic is to show the current status of knowledge and progress in the study of plant adaptation and tolerance to drought in wheat. This will encompass research from a range of scales, from the whole plant to the molecular level, including tolerant and sensitive gene network studies. The topic requires a wide and diverse range of modern technologies, scientific approaches and research ideas aimed towards achieving a better understanding of all aspects of drought responses and their application for better tolerance in wheat.
The scope of the Research Topic includes, but is not limited to, the following areas:
• Wheat plant growth and development in water-deficit conditions, grain yield and quality under the stress;
• Changes in morphology, physiology and biochemistry in response to drought stress, including carbohydrate synthesis/metabolism in grain;
• Plant genetics, genomics, transcriptomics and molecular marker analyses to study plant sensitivity and tolerance to drought;
• Mendelian genetics, epigenetics, gene silencing, RNAi, siRNA and characterization of miRNA for drought tolerance;
• Gene identification and functional analysis in stressed plants;
• qPCR and digital PCR for gene expression and their regulation in dry environments;
• TALENs and CRISPR/Cas9 based gene editing approaches for the development of drought-tolerant transgenic plants
Please note: descriptive studies that report responses of growth, yield, or quality to treatments will not be considered if they do not progress the physiological understanding of these responses.
