How Tomato Plants Use Their Roots to Ration Water During Drought

Andy Fell — January 02, 2024 - 11:32am

Plants have to be flexible to survive environmental changes, and the adaptive methods they deploy must often be as changeable as the shifts in climate and condition to which they adapt. To cope with drought, plant roots produce a water-repellent polymer called suberin that blocks water from flowing up towards the leaves, where it would quickly evaporate. Without suberin, the resulting water loss would be like leaving the tap running.

Will a Wet Winter End Water Woes?

After a series of dry winters in California, the 2022-23 season has brought a series of storms filling reservoirs and piling up the Sierra snowpack. The turnaround led Governor Gavin Newsom to announce the end of some drought-related conservation measures last Friday.

Scientists Unlock Key to Drought-Resistant Wheat Plants with Longer Roots

Andy Fell — February 27, 2023 - 3:33pm

Growing wheat in drought conditions may be easier in the future, thanks to new genetic research out of �°��ϲ��Ļ��Ϣ Davis.

An international team of scientists found that the right number of copies of a specific group of genes can stimulate longer root growth, enabling wheat plants to pull water from deeper supplies. The resulting plants have more biomass and produce higher grain yield, according to a paper published in the journal Nature Communications.

Leaks an Untapped Opportunity for Water Savings

Katherine E Kerlin — March 07, 2022 - 11:00am

Before a drop of treated water in California ever reaches a consumer’s faucet, about 8% of it has already been wasted due to leaks in the delivery system. Nationally, the waste is even higher, at 17%. This represents an untapped opportunity for water savings, according to a study from the University of California, Davis.
