Interesting anecdote: ever since "supply chain issues" became a thing, my local big name grocery stores (Kroger, etc.) have had much smaller but much more flavorful produce as they've resorted to sourcing more locally. Also more expensive, at first, and they go bad/get bruised much faster than they get sold, so they get marked down back to affordability within a few days of a shipment, until there are none left and the cycle repeats. I can't say I mind the change.

> Good nutrition was one reason: Isotopic tracers revealed the plants with extra copies of OsDREB1C took up extra nitrogen through their roots and moved more of it to the shoots.

Extra nitrogen -> more protein (not water).
