News Articles Featuring Siela Maximova

Discovery of chemical clue may lead to solving cacao's black pod rot mystery

The finding of relatively high levels of the antimicrobial compound clovamide in the leaves of a disease-resistant strain of cacao has significant implications for breeding trees that can tolerate black pod rot, according to Penn State researchers who conducted a novel study.

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.

These Kids Have Come 500 Miles To Do Science And Make A Difference

The road between Arauquita, relatively near Colombia’s border with Venezuela, and the nation’s capital in Bogota stretches over 800 kilometers (500 miles), but for one week in October, a special group bridged that gap in more ways than one.

Guiltinan, Maximova receive the 2019 Kopp International Achievement Award

Mark Guiltinan, professor of plant molecular biology, and Siela Maximova, research professor of plant biotechnology, both in the College of Agricultural Sciences, are the recipients of Penn State's 2019 W. LaMarr Kopp International Achievement Award.

Searching for Chocolate’s Roots, and Enemies, in Colombia’s Wilderness

A newfound peace has spurred the hunt for disease-resistant wild cacao within the nation’s borders.
