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...

This week much of California is under a heat advisory or excessive heat warning, with high temperatures estimated to range from 90 to 108 degrees. Many home gardeners are wondering how they can help their plants, trees or shrubs survive the intense summer heat.
“We are getting a lot of inquiries around the state from people worried about how the extreme temperatures are going to affect the plants or trees in their yards,” said Missy Gable, director of the UC Master Gardener Program. “With a little extra planning, you can help your garden beat the heat and survive the hot summer weather.”

As sorghum plants cope with drought conditions, the plants' roots and adjoining microbial communities are communicating in a chemical language that appears to improve the plants' chances under water stress.
“It's amazing,” said Peggy Lemaux, UC Cooperative Extension specialist. “We know there are lots of microbes in the soil and, for the most part, ones in the surrounding soil stayed the same under drought conditions. We only saw changes in those microbes closely associated with the roots.”
The role of drought in restructuring the root microbiome was the first published discovery to come out of a sweeping drought research project underway since 2015...

After the Central Valley Hmong Agriculture radio show last week, the phones at the UC Cooperative Extension office in Fresno County were buzzing non-stop with farmers anxious to apply for state grants to improve irrigation systems and energy efficiency. Michael Yang, UCCE Hmong agricultural assistant, has hosted the one-hour show each Tuesday afternoon on KBIF 900 AM for 19 years.
“Sometimes we don't see the farmers that often. They are busy on the farm,” Yang said. “But when they hear something (important) like this on the radio, they show up.”
