Transcriptome Profiling to Identify Genes Involved in Non-Target-Site-Based Resistance to Clodinafop-Propargyl in Asia Minor Bluegrass (Polypogon fugax)

open access: yesAgronomy, 2022
Asia Minor bluegrass (Polypogon fugax Nees ex Steud.) is a problematic grass weed of winter crops in China, where some populations have become resistant to herbicides. Previously, we identified a P.

The Individual and Combined Effects of Warming and Atrazine on Lithobates pipiens Phenotypes: Implications for Frog Declines

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Amphibians are the most threatened vertebrate class globally. Climate change, agrochemicals, and/or pathogens and parasites are implicated in contributing to amphibian declines, either singly or in combination. We investigated individual and combined effects of elevated temperatures and atrazine (2.0 μg/L) on Lithobates [formerly Rana] pipiens

Evolutionary-thinking in agricultural weed management [PDF]

open access: yes, 2009
Agricultural weeds evolve in response to crop cultivation. Nevertheless, the central importance of evolutionary ecology for understanding weed invasion, persistence and management in agroecosystems is not widely acknowledged.

Nitrogen rates shaping rice yield and groundwater nitrate in the Jamuna River basin of north central Bangladesh

open access: yesJSFA reports, EarlyView.
Abstract Background Understanding how varying nitrogen fertilizer rates influence both rice productivity and groundwater nitrate contamination is critical for ensuring sustainable crop production and environmental protection in the Jamuna River Basin of north‐central Bangladesh.

Multiple herbicide resistance in Lolium multiflorum and identification of conserved regulatory elements of herbicide resistance genes

open access: yesFrontiers in Plant Science, 2016
Herbicide resistance is a ubiquitous challenge to herbicide sustainability and a looming threat to control weeds in crops. Recently four genes were found constituently over-expressed in herbicide resistant individuals of Lolium rigidum, a close relative ...

Herbicide-resistant weeds : from research and knowledge to future needs [PDF]

open access: yes, 2013
Synthetic herbicides have been used globally to control weeds in major field crops. This has imposed a strong selection for any trait that enables plant populations to survive and reproduce in the presence of the herbicide.

Predicting long‐term population viability for an imperiled salamander under future climate changes

open access: yesThe Journal of Wildlife Management, EarlyView.
We evaluated the long‐term viability of 2 reticulated flatwoods salamander (Ambystoma bishopi) populations in response to multiple future climate change scenarios. We found that there is a high probability of extinction by 2100 under some scenarios, mostly driven by severe droughts and repeated reproductive failure. Conservation actions should focus on

INFLUENCE OF GLYPHOSATE ON SUSCEPTIBLE AND RESISTANT RYEGRASS POPULATIONS TO HERBICIDE [PDF]

open access: yesPlanta Daninha, 2017
In Brazil, ryegrass (Lolium multiflorum) has been identified as resistant to glyphosate, becoming a major problem, especially in crops cultivated in the winter season. This herbicide can indirectly affect photosynthesis by inhibiting biosynthesis of many

Crop biotechnology: prospects and opportunities [PDF]

open access: yes, 2010
SUMMARYThis paper is a brief review summarizing some of the important areas of activity in crop biotechnology likely to be exploited over the medium term (10–20 years), with an emphasis on agronomic traits.

Metabolism of the herbicide atrazine by Rhodococcus strains [PDF]

open access: yesApplied and Environmental Microbiology, 1993
Rhodococcus strains were screened for their ability to degrade the herbicide atrazine. Only rhodococci that degrade the herbicide EPTC (s-ethyl-dipropylthiocarbamate) metabolized atrazine. Rhodococcus strain TE1 metabolized atrazine under aerobic conditions to produce deethyl- and deisopropylatrazine, which were not degraded further and which ...
