At the Climate-resilient Agronomy Lab, PSTU, we trace how a rice or cotton plant senses submergence, salinity, drought, and heat - from an ERF transcription factor switching on inside the nucleus to a silicon-amended field plot standing through a tidal surge at Dumki. Four pillars, one bench-to-field pipeline.
