Abstract excerpt
Salt stress is a major abiotic constraint limiting global crop production. Oat (Avena sativa L.), an allohexaploid cereal renowned for robust stress tolerance, remains poorly understood in terms of the molecular mechanisms underlying its response to salt stress. Here, we perform transcriptome profiling across multiple developmental stages and tissues of oat under salt stress, and construct the co-expression...
