Interactions between prosulfocarb and trifluralin metabolism in annual ryegrass (Lolium rigidum)
Metabolism of prosulfocarb and trifluralin was investigated in L. rigidum populations with different levels of resistance to prosulfocarb, trifluralin and also pyroxasulfone, which is detoxified by glutathione (GSH) conjugation.
A novel mutation in SoIAA20 confers cross-resistance to 2,4-Dichlorophenoxyacetic acid and other auxinic herbicides in Sonchus oleraceus
The paired deletion flanking the degron region of SoIAA20 likely provides resistance to 2,4-D by restricting the movement of 2,4-D from the treated tissue to the rest of the plant.
Characterisation of low-level pyrasulfotole resistance and the role of herbicide translocation in wild radish (Raphanus raphanistrum)
Previous studies have shown a wide range of 2,4-D translocation phenotypes in resistant populations of the agricultural weed Raphanus raphanistrum, but it was hypothesised that enhanced movement out of the apical meristem could contribute to resistance.
Focus on the Crop Not the Weed: Canola Identification for Precision Weed Management Using Deep Learning
This paper uses deep learning to explore a novel approach via targeted segmentation mapping of crop plants rather than weeds, focusing on canola (Brassica napus) as the target crop.
Distribution, frequency and molecular basis of clethodim and quizalofop resistance in brome grass (Bromus diandrus)
The identification of target-site-based herbicide resistance in another polyploid weed species provides an opportunity for closer examination of how rapidly resistance evolves in these species under field conditions.
Early silique-shedding wild radish (Raphanus raphanistrum L.) phenotypes persist in a long-term harvest weed seed control managed field in Western Australia
This study introduces a wild radish population collected from Yelbeni in the Western Australian grainbelt that evolved an early silique abscission (shedding) trait to persist despite long-term harvest weed seed control (HWSC) use.
Pyroxasulfone metabolism in resistant Lolium rigidum: is it all down to GST activity?
Resistance to the herbicide pyroxasulfone is slowly but steadily increasing in agricultural weeds. The evolved resistance of one Lolium rigidum population has been attributed to…
Adaptations in wild radish (Raphanus raphanistrum) flowering time, Part 2: Harvest weed seed control shortens flowering by twelve days
This study investigated the effects of repeated HWSC on the evolution of R. raphanistrum flowering dates, using two methods: an adaptation of the SOMER model that included flowering genes (called SOMEF); and a mathematical calculation of the endpoints of flowering date evolution utilizing the relevant life-history equations
Adaptations in wild radish (Raphanus raphanistrum) flowering time, Part 1: Individual-based modeling of a polygenic trait
This study investigated replicating six generations of glasshouse-based flowering date selection in wild radish (Raphanus raphanistrum L.) using an adaptation of the population model SOMER (Spatial Orientated Modelling of Evolutionary Resistance).
