Gene turnover in the common ancestor of all C4 grasses

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, EarlyView.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

Stability studies of cynaropicrin–major sesquiterpene lactone of Cynara cardunculus leaves

Pest Management Science, EarlyView.
This study investigated its stability under high temperature and pH, mimicking agronomic extremes and under soil context. Bioassays demonstrated that degradation products exhibited higher phytotoxic activity than cynaropicrin and deacylcynaropicrin. This is the first study about cynaropicrin's stability, characterizing degradation products, and their ...

Taxonomic research priorities for the conservation of the South African flora

South African Journal of Science, 2013
Taxonomic revisions, monographs and floras are the most important, and often the only source of data for assessing the extinction risk of plants, with recent revisions contributing to more accurate assessments.

Behavioural manipulation of the cabbage stem flea beetle (Psylliodes chrysocephala L): Prospects for push–pull strategies in oilseed rape

Pest Management Science, EarlyView.
Behavioural manipulation of Psylliodes chrysocephala provides promising opportunities for sustainable pest management in oilseed rape systems. This review synthesises evidence on glucosinolates and their volatile isothiocyanate derivatives as phagostimulants and attractants, alongside the repellent or antifeedant effects of non‐host plants, plant ...

Effects of elevated CO2 and temperature on cocklebur (Xanthium strumarium L.) and its herbicide response

Pest Management Science, EarlyView.
Elevated CO2 promotes the growth of Xanthium strumarium while increasing its susceptibility to the systemic herbicide trifloxysulfuron‐sodium. The efficacy of the soil‐active herbicide fluometuron remains unaffected by changes in CO2 concentration and temperature.

Dietary and Ranging Behavior of Semi‐Free Ranging Lemur catta and Varecia rubra at Myakka City Lemur Reserve, Florida, USA

Zoo Biology, EarlyView.
Betsiboka, a female red ruffed lemur (Varecia rubra) eating Carolina redroot in the Tower forest. ABSTRACT Lemurs are severely threatened due to anthropogenic habitat loss and climate change. Therefore, understanding how lemurs adapt their diets to novel habitats is critically important for maintaining healthy wild populations and effectively managing ...

The role of arbuscular mycorrhizal fungi in the competition between invasive and native plants depends on the soil nitrogen form

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant invasion and nitrogen (N) deposition are escalating global change threats. Arbuscular mycorrhizal fungi (AMF) are increasingly recognized as critical mediators of plant invasion success, largely through their role in enhancing host nutrient acquisition.

Trade‐offs between soil biodiversity and agricultural expansion: Evidence from litter decomposition dynamics in Madagascar

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Home‐Field Advantage (HFA) theory—positing that litter decomposes faster at its site of origin—allows us to disentangle the respective influences of litter quality, soil biota composition, and microclimate on shifts in litter decomposition following land use conversion.
