You hear it every time drought returns to California: “Turn off the faucet when you brush your teeth.” “Collect shower water in a bucket before it warms up.”

While valuable, these tried and true drought resilience strategies can also deflect attention from the monumental challenges posed by droughts to natural areas, waterways, agriculture and people in California. Far-sighted and discerning management of the state's annual precipitation and groundwater is critical, particularly as droughts become more frequent due to climate change, said Faith Kearns, the academic coordinator of UC's California Institute for Water...

UC Master Gardener Francie Murphy was pruning the succulents in her San Diego front yard when an unfortunate accident catalyzed her commitment to communicating the dangers of toxic plants. She trimmed a stem on her drought-tolerant pencil milk bush and milky sap spurted into one eye, causing stinging pain.

“I tried to wipe it out, and in doing so got in both eyes. I was blinded. The pain was unbelievable,” she said.

A nearby friend rushed her to the emergency room where the doctor diagnosed chemical burns to her corneas and washed her eyes with two liters of saline water each. Murphy removed the plant from her garden, but saw it growing throughout her...

Scorching temperatures and parched earth are no match for the sorghum plant — this cereal crop, native to Africa, will remain green and productive, even under conditions that would render other plants brown, brittle and barren.

A new study published this week in the journal Proceedings of the National Academy of Sciences provides the first detailed look at how the plant exercises exquisite control over its genome — switching some genes on and some genes off at the first sign of water scarcity, and again when water returns — to survive when its surroundings turn harsh and arid. 

“With this research, we are laying the...
