The DlamiR156-DlaSPL60-DlaP5CS1 cascade directly regulates proline synthesis, conferring drought tolerance in Ma bamboo (Dendrocalamus latiflorus Munro).
Drought stress disrupts cellular homeostasis and severely limits plant growth. Although proline accumulation is a major adaptive response to water deficit, how drought-responsive regulatory networks control proline biosynthesis in woody grasses remains poorly understood. Here, we combined genetic manipulation, molecula...
