Jacob Barney’s students say bon appétit to invasive species

Rose Peterson of Norfolk, Virginia, was recently whipping up some pesto, which is generally made with basil, pine nuts, olive oil, and Parmesan cheese.

But the Virginia Tech senior skipped the basil and instead substituted garlic mustard, a common weed that is one of many invasive plants that are not only ubiquitous, but also delicious.

“Garlic mustard grows commonly in lawns,” said Peterson, who harvested some from her aunt’s house in New Jersey over Thanksgiving break. “You could probably forage some on the Drillfield, too.”

Peterson, who is majoring in biology, made the dish for her biological invasions class at Virginia Tech. For their end of the semester project, students had to not only tell the history of invasive species, they had to cook up a delectable dish to share with the class taught by Jacob Barney.

Westwood leads workshop on plant genomics and bioinformatics in Morocco

Group of Morocco workshop participants.

Participants of the workshop in Morocco.

A group of US researchers with expertise in parasitic plant genomics recently travelled to Morocco to exchange information and coordinate research with Moroccan colleagues. Over 10 days of discussions and field visits, the group sought to connect the fundamental biology of plant genomes with the goal of improving faba bean production in Morocco.

The parasitic plant Orobanche crenata (crenate broomrape) is a devastating weed in North Africa. It primarily attacks faba bean in Morocco, attaching to the roots of the crop and growing unseen in the soil until eventually producing a large floral shoot that emerges above ground. The effect of parasitism on this important crop is devastating, with yields reduced to zero under conditions of heavy parasite infestation. Despite decades of plant breeding effort, few cultivars of faba bean have resistance to the parasite and has led to a precipitous decline in acreage under faba bean cultivation. Into this grim situation the new technologies of genomics brings hope of understanding plant parasitism and breeding improved faba bean varieties that can withstand Orobanche attack. The Moroccan government recently began to invest in “next-generation” sequencing technology with the goal of improving faba bean and other crops of national importance. However, although next generation sequencing is powerful, it generates massive quantities of data that pose new challenges for analysis and interpretation. Continue reading
