Anatomy And Essential Oils From Aerial Organs In Three Species Of Aldama (asteraceaeheliantheae) That Have A Difficult Delimitation [PDF]
, 2015 Recently, molecular analysis caused the South American Viguiera Kunth species to be transferred to Aldama La Llave. However, the circumscription has not been established for certain of the South American species, including Aldama filifolia (Sch.Bip.

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

INVESTIGATING THE IMPACT OF RETICULATE EVOLUTION AND PARALOGY IN PHYLOGENOMIC STUDIES USING THE COMPLEX GENUS PACKERA (ASTERACEAE: SENECIONEAE) [PDF]
, 2023 Underlying discordance in phylogenomic studies is becoming more common, and the answer is not as simple as adding more data. Biological processes such as polyploidy, hybridization, and incomplete lineage sorting are main contributors to these issues and ...

Pest Management Science, EarlyView.Root‐focused resistance in chicory reduces defenses in leaves, impairing root aphids but enhancing foliar aphid performance. Selecting root resistance can create unintended trade‐offs across plant organs. Abstract BACKGROUND Plants are constantly exposed to a wide range of herbivores at both aboveground (AG) and belowground (BG) levels, involving ...

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 ...
