Scientists catalogued which genes activate in Siberian wildrye grass when it faces drought or cold, finding that the plant uses a separate set of genetic tools for each stress type. The work lays groundwork for breeding tougher grasses suited to dry or freezing conditions.
1
Leaves were sampled across multiple stages of each stress event, capturing how gene activity shifts as drought and cold intensify over time
2
Drought tolerance and cold resistance in Siberian wildrye operate through distinct molecular pathways rather than a shared stress response
3
Next-generation RNA sequencing produced a genome-wide catalogue of stress-responsive genes, giving breeders concrete targets for improving resilience in forage and rangeland grasses
