A second cycle of combined heat and drought in potato leaves shows transcriptional memory that primes abscisic acid biosynthesis via StNCED3 and StWRKY33b.
- Why it matters: Combined, recurrent abiotic stresses require regulatory mechanisms that allow efficient responses and priming, but the chromatin and transcriptional basis of stress memory in crops is unclear.
- What they did: Leaves from two genetically distinct potato cultivars were profiled for chromatin accessibility and gene expression after prolonged heat, drought, waterlogging, and combined heat and drought.
- The result: Most accessibility changes were stress-specific, yet drought triggered a distinct transcriptional program with strong chaperone induction and dampened abscisic acid signalling, while the second combined-stress cycle recalled StNCED3 and StWRKY33b activity.
