Cauliflower mosaic virus naturally infects wild radish (Raphanus raphanistrum) in Brazil [PDF]

open access: yesAustralasian Plant Disease Notes, 2019
Cauliflower mosaic virus (CaMV) infects species of Brassicaceae worldwide, including weeds that can act as virus reservoirs. In a survey carried out in brassica fields, we detected CaMV infecting wild radish (Raphanus raphanistrum) from Southeast and Midwest of Brazil. To our knowledge, this is the first report of CaMV infecting this weed in Brazil.

Effects of Fertilizer Sources and Tillage Regimes on Weed Species Composition and Functional Diversity in the 4‐Year of Durum Wheat–Potato Rotation

open access: yesWeed Biology and Management, Volume 25, Issue 3, September 2025.
ABSTRACT Designing environmental‐friendly approaches to mitigate weed pressure in agroecosystems is an urgent priority. A field experiment was conducted in 2014/2015 and 2015/2016 to evaluate fertilizer source and soil tillage on weed community composition in durum wheat–potato rotation.

Natural variation of response to glyphosate in Sinapis alba (Brassicaceae): Physiological effects, shikimate accumulation and genetic mechanisms

open access: yesWeed Research, Volume 65, Issue 5, September/October 2025.
Abstract Glyphosate is the most widely used herbicide worldwide, and glyphosate‐resistant weeds have increased globally. Resistance mechanisms, including target‐site resistance (TSR) and non‐target‐site resistance (NTSR), are well documented, but their extent and importance are poorly understood among biotypes. This study examines the natural variation

Detecting and Mapping Invasive Species Across Riparian Corridors via Object Detection Approaches in UAV Imagery: An Example of Impatiens glandulifera

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
Riparian zones in the United Kingdom are diverse but prone to anthropogenic changes and invasive species like impatiens glandulifera. This study introduces a method to identify and map these flowers using a computer vision framework and UAV imagery, wrapped into an executable program called the semi‐automatic thresholding tool (SATT). Validation showed

Feeding preferences of Microtheca punctigera (Achard) (Coleoptera: Chrysomelidae) for some Brassicaceae plants in multiple-choice assays Preferência alimentar de Microtheca punctigera (Achard) (Coleoptera: Chrysomelidae) por algumas crucíferas em testes de mútipla escolha

open access: yesScientia Agricola, 2005
Host plant feeding preference is important basic information for the development of insect management strategies. Multiple-choice feeding preference assays were conducted in the laboratory for the chrysomelid beetle, Microtheca punctigera (Achard ...

The biology of Canadian weeds. 132. Raphanus raphanistrum L. [PDF]

open access: yesCanadian Journal of Plant Science, 2005
A review of biological information is provided for Raphanus raphanistrum L. Native to the Mediterranean region, the species is widely introduced and naturalized in temperate regions around the world. In Canada, it currently occurs in all provinces except Saskatchewan and Manitoba, has only a limited distribution in Alberta, and is also absent from the

Transgenerational Imprints of Sequential Herbivory on Soybean Physiology and Fitness Traits

open access: yesPlant-Environment Interactions, Volume 6, Issue 4, August 2025.
ABSTRACT Sequential herbivory leads to a multitude of effects on plants, influencing processes like growth, physiology, defense, and fitness. However, whether the sequential herbivore attack can elicit any transgenerational consequences is poorly examined.
