Ophiorrhiza echinata, a new species of Rubiaceae from the southern Western Ghats, India

open access: yesNordic Journal of Botany, EarlyView.
A new species of the genus Ophiorrhiza (Rubiaceae) is described and illustrated from the Idukki District of Kerala, Western Ghats, India. The new species is allied to Ophiorrhiza caudata C.E.C.Fisch. and Ophiorrhiza munnarensis C.E.C.Fisch, but differs in having echinate young stem, leaf lateral nerve pairs 8–14, triangular, caducous stipules, 14.0–23 ...

A notable new narrow‐endemic species of Jurinea (Asteraceae) from the subalpine region of western Iran

open access: yesNordic Journal of Botany, EarlyView.
Extensive field studies in remote areas of Chaharmahal and Bakhtiari Province, Iran, resulted in the identification of a novel Jurinea species (Asteraceae: subtribe Saussureinae). Jurinea kuhrangensis sp. nov., a chasmophytic species endemic to limestone outcrops in the subalpine region of Kuhrang County, is formally documented in this study ...

Plant defense strategies: The dual armor of disease resistance and tolerance

open access: yesNew Plant Protection, EarlyView.
Plants employ dual strategies against pathogens: Resistance limits invasion via immune responses, whereas tolerance mitigates damage to sustain growth—together enhancing survival under infections. Abstract Pathogen infections pose a significant threat to plant health, global food security, and ecosystems.

Ectomycorrhizal fungi and root water uptake respond independently to water availability

open access: yesOikos, EarlyView.
Temperate forests on their warm and dry distribution limits are expected to be most vulnerable to reductions in water availability. This prediction is mostly based on studies assessing single forest functions, mainly growth. Water and nutrient cycling are functions that rely on tree roots and their symbiotic association with ectomycorrhizal (ECM) fungi.
