Plants defend against insects by inducing 'leaky gut syndrome'

Plants may induce "leaky gut syndrome" — permeability of the gut lining — in insects as part of a multipronged strategy for protecting themselves from being eaten, according to researchers at Penn State.

Parasitic plants use stolen genes to make them better parasites

Some parasitic plants steal genetic material from their host plants and use the stolen genes to more effectively siphon off the host’s nutrients. A new study led by researchers at Penn State and Virginia Tech reveals that the parasitic plant dodder has stolen a large amount of genetic material from its hosts, including over 100 functional genes.

Some green ash trees show some resistance to emerald ash borers

Genes in green ash trees that may confer some resistance to attacks by the emerald ash borer express themselves only once the tree detects the invasive beetle's feeding, according to Penn State researchers.

Cell Dynamics takes center stage at 2019 Plant Biology Symposium

The 22nd Penn State Plant Biology Symposium was "a great success," according to organizers, who joined it with the Plant Cell Dynamics VIII meeting in an effort to encourage wider collaborations.

Insect-deterring sorghum compounds may be eco-friendly pesticide

Compounds produced by sorghum plants to defend against insect feeding could be isolated, synthesized and used as a targeted, nontoxic insect deterrent, according to researchers who studied plant-insect interactions that included field, greenhouse and laboratory components.

Plant Biology Student Chris Benson Lands $90,000 Grant From United States Golf Association

Chris Benson's work concerns adaptability in the turfgrass species Poa annua, with plans to guide breeding efforts for a phenotypically stable variety with applications on golf course putting greens. That research has attracted significant support from the USGA.

Farmers in Angonia, Mozambique, happy with the performance of new varieties of common bean developed by an international partnership of plant scientists that included researchers in Penn State's College of Agricultural Sciences, pose among plants in a bean field. Plant breeding field trials have been conducted with bean growers in multiple regions of the country in southeast Africa. IMAGE: JIMMY BURRIDGE

Penn State root research results in breeding of improved bean plants for Africa

In the culmination of more than a decade of research on root traits conducted by Penn State plant scientists, about three tons of seed for common bean plants specifically bred to thrive in the barren soils of Mozambique will be distributed there Dec. 11.
