A team of researchers, led by a University of California, Davis, plant scientist, has identified a lettuce gene and related enzyme that put the brakes on germination during hot weather — a discovery that could lead to lettuces that can sprout year-round, even at high temperatures.

The study also included researchers from Arcadia Biosciences and Acharya N.G. Ranga Agricultural University, India.

The finding is particularly important to the nearly $2 billion lettuce industries of California and Arizona, which together produce more than 90 percent of the nation’s lettuce. The study results appear online in the journal The Plant Cell.

“Discovery of the genes will enable plant breeders to develop lettuce varieties that can better germinate and grow to maturity under high temperatures,” said the study’s lead author Kent Bradford, a professor of plant sciences and director of the UC Davis Seed Biotechnology Center... Read More

The San Joaquin Valley Air Pollution Control District reminds an Air Alert to curb vehicle emissions which can lead to higher ozone levels is in effect for the first week of September.

The district issued an Ar Alert for Aug. 23 through Aug. 29 and thanks to the cooperation of residents and businesses, no community in the district exceeded federal, health- based ozone standards. Doing so can lead to large fines.
