harnessing genetic variation at regulatory regions to fine-tune traits for climate-resilient crops

Climate change is making it more challenging to meet the food demands of a growing global *** food produc-tion relies on continual crop improvements to generate higher and more stable yields,especially with increasingly unpredictable environments and less arable *** improvement of traits that promote climate resilience and resource utilization,for example,greater photosynthetic capacity,increased nitrogen use efficiency,and optimized root and shoot architecture,repre-sents a promising avenue for engineering crops to yield more with less(Evans and Lawson,2020).A key challenge for crop engineering is optimizing performance in specific environments.

There are many challenges facing the development of high-yielding,nutritious crops for future *** limiting factor is generation time,which prolongs research and plant breeding *** advances in speed breeding protocols have dramatically reduced generation time for many short-day and long-day species by optimizing lightand temperature conditions during plant ***,winter crops with a vernalization requirement stillrequire upto 6-10weeks in low-temperature conditions before thetransition to ***,we tested a suite of environmental conditions and protocols to investigate whether the vernalization process can be *** identified a vernalization method consisting of exposing seeds at the soil surface to an extended photoperiod of 22 h day:2 h night at 10°C with transfer to speed breeding conditions that dramatically reduces generation time in both winter wheat(Triticum aestivum)and winter barley(hordeum vulgare).Implementation of the speedvernalization protocolfollowed byspeedbreedingallowed the completion ofuptofivegenerations per yearforwinter wheat or barley,whereas only two generations can be typically completed under standard vernalization and plant growth *** speed vernalization protocol developed in this study has great potential to accelerate biological research and breeding outcomes for winter crops.
