Success Stories of the Week:
Oregon State University is developing CRISPR gene-editing
technology to destroy the genes in plants that cause the ongoing outbreak of
sudden oak death in Oregon and California and other diseases.
A virulent plant-disease agent called Phytophthora sojae
knocks out resistance in its soybean host by sending out a “decoy” protein to
confuse the plant’s immune system.
The newly uncovered mechanism may explain why the group
of plant pathogens known as Phytophthora are so devastating to crops and
natural ecosystems worldwide.
The study provides a vivid glimpse into the evolutionary
arms race between Phytophthora species and their hosts. The researchers focused
on P. sojae, which attacks soybeans, and particularly on a critical protein
called a xyloendoglucanase, or XEG. Read more online.

With foodborne illness
outbreaks from harmful pathogens occurring, there is a need to ensure the consumption of cleaner
produce.
The University of Delaware’s
Haiqiang Chen is trying to accomplish a 99.7% reduction of salmonella with his new ultraviolet (UV)
light oven, a product that will combine UV light with water that is stirred up
to put the cleanest produce possible on the plates of consumers. Read about this work here.

Common crop chemical leaves bees susceptible to deadly viruses according to researchers at Penn State University
A chemical that is thought to be safe and is, therefore, widely used on crops — such as almonds, wine grapes, and tree fruits — to boost the performance of pesticides, makes honey bee larvae significantly more susceptible to a deadly virus, according to researchers at Penn State and the U.S. Department of Agriculture. "In the lab, we found that the commonly used organosilicone adjuvant, Sylgard 309, negatively impacts the health of honey bee larvae by increasing their susceptibility to a common bee pathogen, the Black Queen Cell Virus," said Julia Fine, entomology graduate student, Penn State.

University: Local Research with Global Effects
Virginia State University is working on a project to improve simultaneous removal of
nitrogen and phosphorus from municipal wastewater; examine tepary bean, a
Native American crop, for drought tolerance and the need for crop
diversification; and many other research projects. Read the 2016 VSU Impacts Report.
Iowa Women in Agriculture
Women Managing Cattle is a program for farm women to
meet, share their experiences in the cattle industry, and learn from Iowa State
University Extension and Outreach specialists. Women are important in
agriculture, and the cattle business is no different. The Women Managing Cattle
program hopes to build relationships and educate women in the cattle business
by focusing on cost of production, marketing strategies and production systems.
