Nature's Shield: Exploring Nonglandular Trichomes (NGT) as Key Players in Plant Defense Mechanisms

Plant Direct, Volume 9, Issue 11, November 2025.
ABSTRACT Trichomes are found on almost all terrestrial plants and are derived from epidermal cells. Nonglandular trichomes (NGTs) protect plants from environmental stress, such as pest and pathogen invasion, reduce water loss, and increase resistance to abiotic stressors, including UV radiation, cold, and extreme temperatures.

Are lichens biocompasses? Revisiting an old prediction using new techniques

Plant Biology, Volume 27, Issue 6, Page 1150-1157, October 2025.
The equator‐facing portions of tree trunks receive direct sunlight and create restrictive microclimate conditions for lichens that orient preferentially towards the Earth's poles where trunks are shaded, indicating an optimal zone at the fine‐scale radial dimension.

A pedo‐isotopic approach to study sandy soils of the Brazilian Cerrado in Piauí State

Agrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Sandy soils dominate Brazil's Cerrado biome in Piauí State, yet their organic carbon (OC) stabilization mechanisms and landscape‐driven pedogenesis remain poorly understood. To clarify this topic, the present study proposes a pedo‐isotopic approach to characterize six representative Brazilian Cerrado soils derived from sedimentary rocks in ...
