Maple syrup jars

As maple sugaring season approaches, plant ecologist Kristina Stinson recently received a two-year, $149,800 grant to study the impact of climate change on the quantity and quality of sugar maple sap, including its chemical composition, and of sap from red maples, a species less sensitive to climate change.

UMass students visit Cuban farms and markets with PB faculty member Frank Mangan during winter session. 

Ox power has yet to be replaced by fossil fuels in most of Cuba

Just one of the surprises for five UMass students who visited Cuba with Dr. Frank Mangan in January for a winter session course on food systems was learning that 80 percent of farm and agricultural work handled by tractors and other motorized equipment in the United States is done by teams of oxen in Cuba.

Muvari Tjiurutue receives Dissertation Research Grant from the UMass Amherst Graduate School 

Muvari Tjiurutue, PB PhD graduate student

Muvari Tjiurutue from the Adler Lab has received a $1K research grant from the UMass Amherst Graduate School to support her PhD studies on the interactions between parasitic plants, their hosts and insect herbivores.  The study involves looking at how damage to lupine hosts (Lupinus Texensis) affects herbivory on Indian paintbrush (Castilleja indivisa) parasites via uptake of defense signals or compounds. A comprehensive screening of the plants for alkaloids will be completed in the lab of Phil Stevenson at the University of Greenwich in the UK.

UMass Amherst Researchers Identify a Key Molecule in Nitrogen-Fixing Bacteria

Researcher Dong Wang (Department of Biochemistry and Molecular Biology), along with postdoctoral researcher and lead author Minsoo Kim and former undergraduate student Chris Waters and colleagues at the Noble Foundation in Oklahoma, report in the early online edition of Proceedings of the National Academy of Sciences their discovery of a peptide found in alfalfa that holds the potential to improve crop yields without increasing fertilizer use.  This peptide, DNF4 (also known as NCR211), is a “double agent,” having the ability to support nitrogen-fixing bacteria present inside the plant, while also killing free-living bacteria outside.  Wang’s comments about his research in this area: “Next we want to find out why this peptide helps the bacteria inside the plant, but it can kill free-living bacteria outside the plant. Why does one molecule function as a double agent?”  Read More

SARE award to MS student Caroline Wise

Caroline Wise, PB MS grad student

Caroline Wise (MS, Hashemi Lab) is collaborating on a SARE grant ($177,442) entitled  ‘Developing Best Management Practices for Growing Grain Suitable for Malt in the Northeast’ as Co-PI with Masoud Hashemi of UMass and Heather Darby of UVM.  Wise received a SARE graduate student grant ($13,967) to study "Management practices for production of local malting barley in Northeast". Caroline also participated in a UMass Field Day Presentation: "Impacts of Planting Date, Nitrogen, Cultivar and Zinc on Barley Malt Quality"  where she presented a rationale and summary of her research projects to over 120 participants comprising local growers, and maltsters.

Christina Stonoha to present at Symbiotic Nitrogen Fixation conference in December.

PB PhD graduate student Christina Stonoha

PB PhD graduate student Christina Stonoha has been chosen to give a talk at the 23rd North American Conference on Symbiotic Nitrogen Fixation (NACSNF), December 6-10, 2015 in Ixtapa, Mexico.  Her advisor, Dong Wang, will also be presenting at the event.
