Abiotic stresses impose great impediments on plant growth and crop productivity. Current research aims to not only understand the effects of stress and elucidate its associated biological pathways, but to use this knowledge in generating stress-resistant crops and improving productivity and yield. The latter poses a major challenge due to the dynamism of the yield trait itself, which is influenced by various environmental and genetic factors often exacerbated under climate change.
Light and hormone pathways have long been known to control plant yield and stress tolerance, and thus represent a major target of such studies. For instance, recent evidence indicates that the circadian clock is involved in the abiotic stress response.
Recent advances include the discovery of Phytochrome B as a thermos-sensor in addition to its primary role as a red light photoreceptor, and the identification of Phytochrome Interacting Factors as the master downstream connectors of thermo-morphogenesis, skoto-morphogenesis, abiotic stress tolerance, and flowering pathways. The discovery of noble growth regulators such as strigolactones, phytomelatonin, and new signaling molecules like nitric oxide have also opened multiple doors for improving crop yield.
A deeper understanding of circadian clock signaling such as the evening complex, differential regulation of florigen, and variation of clock organization in different plant systems is critical for designing new stress-tolerant strategies in plants.
This Research Topic therefore welcomes all submissions types on, but is not limited to, the following subthemes:
• Light signaling;
• Circadian clock organization and operations;
• Modulation of hormone pathways for gaining abiotic stress tolerance and for improving yield;
• Genetics and epigenetics of light signaling, clock, and hormone pathways;
• Involvement of light signaling and the circadian clock in abiotic stress tolerance and yield.
