Agricultural parasite avoids evolutionary arms race, shuts down genes of host

A parasitic plant has found a way to circumvent an evolutionary arms race with the host plants from which it steals nutrients, allowing the parasite to thrive on a variety of agriculturally important plants. The parasite dodder, an agricultural pest found on every continent, sends genetic material into its host to shut down host defense genes.

Novel way to ID disease-resistance genes in chocolate-producing trees found

Chocolate-producing cacao trees that are resistant to a major pathogen were identified by an international team of plant geneticists. The findings point the way for plant breeders to develop trees that are tolerant of the disease.

Global Faculty Fellow will create connections between Penn State and Colombia

Siela Maximova, research professor of plant biotechnology, has been named a Global Faculty Fellow in Penn State's College of Agricultural Sciences and a Land Grant University U.S.-Colombia Fulbright Scholar.

One avocado a day helps lower 'bad' cholesterol for heart healthy benefits

Move over, apples — new research from Penn State suggests that eating one avocado a day may help keep “bad cholesterol” at bay. According to the researchers, bad cholesterol can refer to both oxidized low-density lipoprotein (LDL) and small, dense LDL particles.

Mackenzie Named Inaugural Director of Plant Institute

Sally Mackenzie sees a unique opportunity for Penn State to address complex global challenges in an unprecedented way.

Novel use of laser technology reveals interactions between roots, soil organisms

A novel use of a custom laser system — developed in Penn State’s College of Agricultural Sciences eight years ago — allows researchers to see how soil organisms affect plant roots.

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.
