Combined effects of canola plant density and insecticide management strategies on flea beetle abundance, canola defoliation, and yield across the Canadian prairies

open access: yesPest Management Science, EarlyView.
Increasing canola plant density reduced flea beetle abundance per plant and increased yield, independent of region or insecticide use, highlighting its potential as a component of integrated pest management. Abstract The crucifer flea beetle, Phyllotreta cruciferae (Goeze), and the striped flea beetle, Phyllotreta striolata (Fabricius) (Coleoptera ...

Ultrastructural studies of seed coat and cotyledon during rapeseed maturation

open access: yes, 2021
Brassica napus L. (B. napus) is an important oil crop worldwide and it rapidly accumulates oil at late stage of seed maturation. However, little is known about the cellular mechanism of oil accumulation and seed color changes during the late stage of ...

Biogenesis of Mitochondria in Germinating Peanut Cotyledons [PDF]

open access: yesPlant Physiology, 1966
The increase in respiratory activity in germinating peanut cotyledons has been correlated with an actual increase in mitochondria. Using sucrose gradient centrifugation, it was shown that succinoxidase activity is associated with a well-defined band of cell particulates of uniform density, size and ultrastructure.

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

open access: yesPest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

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

open access: yesPest 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.

Arabidopsis FH1 Formin Affects Cotyledon Pavement Cell Shape by Modulating Cytoskeleton Dynamics.

open access: yesPlant and Cell Physiology, 2016
Plant cell morphogenesis involves concerted rearrangements of microtubules and actin microfilaments. We previously reported that FH1, the main Arabidopsis thaliana housekeeping Class I membrane-anchored formin, contributes to actin dynamics and ...

A Lipidomic Analysis Reveals Dynamic Changes of Polar Lipids for Oil Biosynthesis During Cotyledon Development in Perilla frutescens

open access: yesPlants
Perilla (Perilla frutescens) is an important oilseed crop valued for its rich content of nutraceutical compounds and polyunsaturated fatty acids. While triacylglycerol biosynthesis has been studied, the role of polar lipids during seed development ...
