Just like any other organism, plants can get stressed. Usually it’s conditions like heat and drought that lead to this stress, and when they’re stressed, plants might not grow as large or produce as much. This can be a problem for farmers, so many scientists have tried genetically modifying plants to be more resilient.
But plants modified for higher crop yields tend to have a lower stress tolerance because they put more energy into growth than into protection against stresses. Similarly, improving the ability of plants to survive stress often results in plants that produce less because they put more energy into protection than into growth. This conundrum makes it difficult to improve crop production.
Brad Binder, professor of biochemistry and cellular and molecular biology, shares his expertise on plants and their response to stress and how adding ethylene early on can increase both their growth and stress tolerance. Read the full article at The Conversation.
