Shrink or expand? Just relax! Bidirectional grana structural dynamics as early light-induced regulator of photosynthesis. [PDF]

New Phytol
Summary Light‐induced structural changes in thylakoid membranes have been reported for decades, with conflicting data regarding their shrinkage or expansion during dark–light transitions. Understanding these dynamics is important for both fundamental photosynthesis research and agricultural applications. This research investigated the temporal sequence

Sclerified Cork Outperforms the Exodermis: Root Water Permeability Decreases in the Soil-To-Canopy Transition of the Aroid Vine Epipremnum aureum. [PDF]

Physiol Plant
ABSTRACT The aroid vine Epipremnum aureum undergoes changes in habitat and growth axis direction from terrestrial (plagiotropic) to canopy (orthotropic) conditions. Since aerial roots connected to the forest soil are vital for water and nutrient uptake in these vines, we hypothesize that morphophysiological acclimation occurs, enabling root survival ...

Pseudomonas chlororaphis L5 and Enterobacter asburiae L95 biocontrol Dickeya soft rot diseases by quenching virulence factor modulating quorum sensing signal

Microbial Biotechnology, Volume 16, Issue 11, Page 2145-2160, November 2023., 2023
A sensitive VFM biosensor has been constructed to detect the Dickeya VFM quorum sensing signal in this study. Two quorum quenching bacteria with high efficiency to repress Dickeya virulence were screened out by using this VFM biosensor. Abstract Virulence factor modulating (VFM) is a quorum sensing (QS) signal shared by and specific to Dickeya bacteria,

Floral specialization for beetle pollination and its implications for pollen dispersal in an African orchid. [PDF]

Am J Bot
Abstract Premise Pollination by beetles is relatively rare in orchids, and this has been attributed to the clumsy behavior of beetles being unsuitable for the precise pollen transfer mechanisms that characterize the orchid family. We investigated floral specialization for beetle pollination in the rare fire‐dependent South African orchid Disa elegans ...

Target sequence data shed new light on the infrafamilial classification of Araceae

American Journal of Botany, Volume 110, Issue 2, February 2023., 2023
Abstract Premise Recent phylogenetic studies of the Araceae have confirmed the position of the duckweeds nested within the aroids, and the monophyly of a clade containing all the unisexual flowered aroids plus the bisexual‐flowered Calla palustris. The main objective of the present study was to better resolve the deep phylogenetic relationships among ...

Risk assessment for Birds and Mammals

EFSA Journal, Volume 21, Issue 2, February 2023., 2023
Abstract The European Commission asked EFSA to revise the Guidance on the risk assessment for birds and mammals. That guidance described how to perform risk assessment for birds and mammals from plant protection products, containing pesticide active substances, in accordance with Regulation (EU) 1107/2009.

Plant Species Composition and Conservation Values at Dilla University Botanical and Ecotourism Garden, Dilla, Ethiopia

International Journal of Forestry Research, Volume 2023, Issue 1, 2023., 2023
Ethiopia has a diverse topography with higher plant species composition and estimated to the higher proportion of endemic plant species. Currently, several factors drive natural forest destruction in the country, extensive agricultural land expansion triggered by increasing human population is probably the dominant force. The Dilla University Botanical
