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.

Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth

New Phytologist, Volume 247, Issue 5, Page 2042-2048, September 2025.
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...

miR825‐5p‐regulated TNLs govern Arabidopsis resistance to Tetranychus urticae and Pieris brassicae

New Phytologist, Volume 247, Issue 6, Page 2927-2944, September 2025.
Summary MicroRNAs are essential regulators in plant resistance to biotic stresses, but their specific roles in the plant–herbivore context require deeper investigation. Here, we studied how the Arabidopsis miR825‐5p differentially modulates certain TNLs (MRT1, MRT2, and MIST1), triggering defensive responses against the sucking acari Tetranychus ...

A comprehensive review of the genetic control of cooking time in dry beans (Phaseolus vulgaris L.)

PLANTS, PEOPLE, PLANET, Volume 7, Issue 4, Page 934-953, July 2025.
Reducing cooking time could increase dry beans (Phaseolus vulgaris) consumption. Cooking is an essential processing step needed to unlock the nutrients in dry beans and to make them palatable and safe for consumption. Long cooking times have consequences for dry bean use, especially where cooking fuel cost is high and when people prefer foods that are ...
