In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl‐ACP thioesterases (FATs) as primary site of action

Pest Management Science, EarlyView.
In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl‐ACP thioesterases (FATs) as primary site of action. Cinmethylin inhibits FATs, disrupting eukaryotic de novo lipid biosynthesis and causing defects in cell division, elongation and integrity. We confirm FATs as the primary site of action in planta.

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

Environmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

Environmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

LEAFY controls floral meristem identity in Arabidopsis [PDF]

, 1992
The first step in flower development is the generation of a floral meristem by the inflorescence meristem. We have analyzed how this process is affected by mutant alleles of the Arabidopsis gene LEAFY.

Shoot meristem maintenance is controlled by a GRAS-gene mediated signal from differentiating cells [PDF]

, 2002
Plant shoot development depends on the perpetuation of a group of undifferentiated cells in the shoot apical meristem (SAM). In the Petunia mutant hairy meristem (ham), shoot meristems differentiate postembryonically as continuations of the subtending ...

Trace Levels of Triclosan May Affect Root Growth and Morphology in Cultivated Plants

Environmental Toxicology, EarlyView.
ABSTRACT Triclosan (TCS) is a micropollutant frequently detected in biosolids applied to agricultural soils. In soil solution—where it is potentially bioavailable to roots—it occurs at residual concentrations (ng L−1). Nevertheless, the ecotoxicological implications of TCS exposure in agricultural crops at these concentrations are still not fully ...

The Role of Two Homeodomain Genes PENNYWISE(PNY) and POUNDFOOLISH(PNF) in Regulating Meristem Maintenance of Shoot Apical Meristem [PDF]

, 2012
All aerial organs are produced from shoot meristems, which are dynamic self-sustaining structures located at the growing tips of shoots. Shoot meristems are subdivided into discrete domains with distinct functions.

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Light Signaling in Bud Outgrowth and Branching in Plants

Plants, 2014
Branching determines the final shape of plants, which influences adaptation, survival and the visual quality of many species. It is an intricate process that includes bud outgrowth and shoot extension, and these in turn respond to environmental cues and ...

HAIRY MERISTEM with WUSCHEL confines CLAVATA3 expression to the outer apical meristem layers [PDF]

, 2018
The control of the location and activity of stem cells depends on spatial regulation of gene activities in the stem cell niche. Using computational and experimental approaches, we have tested and found support for a hypothesis for gene interactions that ...
