Structural variations among monocot emergent and amphibious species from lakes of the semi-arid region of Bahia, Brazil

Brazilian Journal of Biology
Temporary lakes are common in the semi-arid region of the State of Bahia and form water mirrors in the rainy season. In this period, various vegetal species appear having different life forms adapted to the seasonality conditions of the rainfall regime ...

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

PLANTS, PEOPLE, PLANET, EarlyView.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

A new interpretation on vascular architecture of the cauline system in Commelinaceae (Commelinales).

PLoS ONE, 2019
The vascular system of monocotyledons, including Commelinaceae, has been studied since the 19th century, but to date, the proposed vascular architecture models consist of schematic representations partially based on the authors' interpretation.

Accelerating the prioritisation of plant species with underexplored medicinal potential: The pm4mp (Phylogenetic Methods for Medicinal Plants) R package

PLANTS, PEOPLE, PLANET, EarlyView.
Medicinal plants used in ethnobotanical traditions to treat or prevent diseases have gained renewed interest for their largely untapped potential in drug discovery. In this study, we developed and tested novel methods to prioritise plant species based on their unexplored medicinal potential. By enabling researchers to target the most promising species,

Field investigation of glucosinolates and morphological traits in mitigating Psylliodes chrysocephala larval infestation through crop varieties and companion planting

Pest Management Science, EarlyView.
Genotype and cropping system influenced oilseed rape ecophysiological traits, including glucosinolate compounds (glucoraphanin, glucobrassicanapin, and butyl‐glucosinolates) and biomass, which were linked to Psylliodes chrysocephala larval infestation, with varietal effects stronger than faba bean companion planting.

Amino acid vectorization of salicylic acid enables efficient activation of NPR1‐dependent defense without phytotoxicity

Pest Management Science, EarlyView.
Amino acid‐vectorized salicylic acid activates PR1/NPR1‐dependent defenses without phytotoxicity, showing an efficient strategy for controlled delivery and enhanced plant immunity. Abstract BACKGROUND Addressing global food security under rapid population growth and climate change requires sustainable strategies to protect crops from pathogens while ...

How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

Pest Management Science, EarlyView.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.
