Exploring chemical control of 2,4-D-resistant wild radish (Raphanus raphanistrum) with auxin-related compounds

Dr Danica Goggin

The aim of this study was to determine if compounds involved in auxin biosynthesis, transport and signalling are able to synergise with 2,4-D and increase its ability to control 2,4-D-resistant R. raphanistrum populations.

Subtelomeric 5-enolpyruvylshikimate-3-phosphate synthase copy number variation confers glyphosate resistance in Eleusine indica

Dr Chun Zhang

Resistance to the widely used herbicide, glyphosate, has evolved through target-site CNV in many weedy plant species, including the economically important grass, Eleusine indica (goosegrass); however, the origin and mechanism of these CNVs remain elusive in many weed species due to limited genetic and genomic resources.

Multiple metabolic enzymes can be involved in cross-resistance to 4‑Hydroxyphenylpyruvate-Dioxygenase-inhibiting herbicides in wild radish

Overexpression of the multiple herbicide-metabolizing genes could contribute to HPPD-inhibiting herbicide resistance in this wild radish population.

Metabolic resistance to acetolactate synthase inhibitors in Beckmannia syzigachne: identification of CYP81Q32 and its transcription regulation

Dr Qin Yu and Professor Lang Pan

This study reveals the evolution of an herbicide-metabolizing and resistance-endowing P450 and its transcription regulation in an economically important weedy plant species.

Segmentation of sandplain lupin weeds from morphologically similar narrow-leafed lupins in the field

Researchers successfully trained a segmentation model to detect sandplain lupins and differentiate them from narrow-leafed lupins under field conditions.

Sensitivity of herbicide-resistant Rigid Ryegrass (Lolium rigidum) populations to cinmethylin, a new herbicide site of action

Geide Figueiredo

Rigid ryegrass (Lolium rigidum Gaudin) is the most problematic weed in Australia, with evolved resistance to multiple herbicide sites of action. Selection pressure by cinmethylin (Group 30, a fatty acid thioesterase inhibitor) has been limited because few populations have been exposed to the herbicide since its introduction in 2019. In this study, we examined the sensitivity of L. rigidum populations to this new herbicide.
