Running head: ACCase mutations and herbicide resistance in Lolium species
The acetyl-CoA carboxylase (ACCase)-inhibiting cyclohexanedione herbicide clethodim is used to control grass weeds infesting dicot crops. In Australia clethodim is widely used to control the weed Lolium rigidum. However, clethodim resistant Lolium populations have appeared over the last five years and now are present in many populations across the Western Australian wheat belt (Owen et al. 2007...
متن کاملEffect of herbicide resistance endowing Ile-1781-Leu and Asp-2078-Gly ACCase gene mutations on ACCase kinetics and growth traits in Lolium rigidum
The rate of herbicide resistance evolution in plants depends on fitness traits endowed by alleles in both the presence and absence (resistance cost) of herbicide selection. The effect of two Lolium rigidum spontaneous homozygous target-site resistance-endowing mutations (Ile-1781-Leu, Asp-2078-Gly) on both ACCase activity and various plant growth traits have been investigated here. Relative gro...
متن کاملMutations in the plastidic ACCase gene endowing resistance to ACCase-inhibiting herbicide in Phalaris minor populations from India
Littleseed canarygrass (Phalaris minor Retz.) is one of the most common and troublesome weeds infesting wheat crop in India. Repeated use during the last two decades of the ACCase-inhibiting herbicide (clodinafop) to control this weed has resulted in the occurrence of resistance. Fifty-three P. minor populations were collected from wheat fields in Haryana and Punjab states of India. The dose-re...
متن کاملAnalysis of the Accase Mutation Profile of Italian Ryegrass (Lolium Perenne SSP. Multiflorum) Accessions Resistant to Accase Inhibitors
Lolium perenne ssp. multiflontm (Italian ryegrass) resistant to ACCase inhibiting herbicides has been reported in many wheat producing counties across Arkansas. Resistance is believed to be the result of point mutations creating amino acid substitutions in the CT domain of the plastidic ACCase gene. This study explores the occurrence of mutations in the A CCase gene of ryegrass populations. Pla...
