Inheritance of evolved resistance to a novel herbicide (pyroxasulfone).
Agricultural weeds have rapidly adapted to intensive herbicide selection and resistance to herbicides has evolved within ecological timescales. Yet, the genetic basis of broad-spectrum generalist herbicide resistance is largely unknown. This study aims to determine the genetic control of non-target-site herbicide resistance trait(s) that rapidly evolved under recurrent selection of the novel li...
متن کاملEvolved polygenic herbicide resistance in Lolium rigidum by low-dose herbicide selection within standing genetic variation
The interaction between environment and genetic traits under selection is the basis of evolution. In this study, we have investigated the genetic basis of herbicide resistance in a highly characterized initially herbicide-susceptible Lolium rigidum population recurrently selected with low (below recommended label) doses of the herbicide diclofop-methyl. We report the variability in herbicide re...
متن کاملEvolution of herbicide resistance mechanisms in grass weeds.
Herbicide resistant weeds are becoming increasingly common, threatening global food security. Here, we present BrIFAR: a new model system for the functional study of mechanisms of herbicide resistance in grass weeds. We have developed a large collection of Brachypodium accessions, the BrI collection, representing a wide range of habitats. Wide screening of the responses of the accessions to fou...
متن کاملMechanisms of naturally evolved ethanol resistance in Drosophila melanogaster.
The decaying fruit in which Drosophila melanogaster feed and breed can contain ethanol in concentrations as high as 6-7%. In this cosmopolitan species, populations from temperate regions are consistently more resistant to ethanol poisoning than populations from the tropics, but little is known about the physiological basis of this difference. I show that when exposed to low levels of ethanol va...
متن کاملPhysiological mechanisms of evolved desiccation resistance in Drosophila melanogaster.
We investigated physiological characters associated with water balance in laboratory populations of Drosophila melanogaster selected for resistance to desiccating conditions for over 100 generations. Five replicate, outbred, desiccation-selected (D) populations were compared with their control (C) populations. Water loss rates of female D flies were approximately 40% lower than those of C femal...
