Defender or accomplice? Dual roles of plant vesicle trafficking in restricting and enabling geminiviral systemic infection

New Phytologist, Volume 249, Issue 6, Page 2986-3002, March 2026.
Summary The vesicle trafficking system enables multidirectional cargo fluxes between endomembrane compartments. However, vesicle trafficking plays dual roles during pathogen infections. In plants, it mediates autophagic immune responses but can also be hijacked by pathogens to facilitate successful infections.

Phylogenomic insights into the origin of the Norton grape

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1458-1468, September 2025.
Challenges in viticulture such as disease resistance have renewed interest in underutilized cultivars. The Norton grape, one of the earliest popular North American grape cultivars, holds the potential to produce exceptional wine while being resistant to pests and disease. Yet, the ancestry of the Norton grape is controversial.
