Unraveling the Role of P450 Reductase in Herbicide Metabolic Resistance Mechanism. [PDF]

Plant Direct
ABSTRACT Plants require cytochrome P450 reductase (CPR) to supply two electrons for cytochrome P450 monooxygenase enzymes (P450) to react with an organic substrate. The transfer of electrons to the P450 active site in the P450 catalytic site relies on a robust and intricate CPR:P450 complex in the endoplasmic reticulum membrane.

Multiple Origins or Widespread Gene Flow in Agricultural Fields? Regional Population Genomics of Herbicide Resistance in Bromus tectorum. [PDF]

Mol Ecol
ABSTRACT The repeated evolution of herbicide resistance in agriculture provides an unprecedented opportunity to understand how organisms rapidly respond to strong anthropogenic‐driven selection pressure. We recently identified agricultural populations of the grass species Bromus tectorum L. with resistance to multiple herbicides.

Clash of the Invaders: Competition Dynamics of <i>Bromus tectorum</i> and <i>Ventenata dubia</i> in an Addition Series Study. [PDF]

Ecol Evol
Competitive interactions between co‐occurring invasive species can have detrimental impacts on native community composition and cause countereffective responses to management. The goal of this research was to elucidate competitive dynamics between Bromus tectorum and Ventenata dubia, two invasive winter annual grasses found in the western United States

Ten‐year ecological responses to fuel treatments within semiarid Wyoming big sagebrush ecosystems

Ecosphere, 2022
Sagebrush ecosystems of western North America are threatened by invasive annual grasses and wildfires that can remove fire‐intolerant shrubs for decades. Fuel reduction treatments are used ostensibly to aid in fire suppression, conserve wildlife habitat,

Herbicide effects on the establishment of a native bunchgrass in annual grass invaded areas: Indaziflam versus imazapic

Ecological Solutions and Evidence, 2021
1. Annual grass invasion is transforming the western United States and driving a need for restoration techniques that can both reduce exotic annual grass abundance and allow revegetation of native species.

The Ghost of Outcrossing Past in Downy Brome, an Inbreeding Annual Grass [PDF]

Journal of Heredity, 2013
We investigated the frequency of outcrossing in downy brome (Bromus tectorum L.), a cleistogamous weedy annual grass, in both common garden and wild populations, using microsatellite and single nucleotide polymorphic (SNP) markers. In the common garden study, 25 lines with strongly contrasting genotypes were planted in close proximity. We fingerprinted

Effects of Elevated Temperature and CO₂ Concentration on Seedling Growth of Ventenata dubia (Leers) Coss. and Bromus tectorum L.

Agronomy, 2020
The impacts of climate change are expected to alter the abundance and distribution of invasive annual grasses, such as Bromus tectorum L. (cheatgrass) and Ventenata dubia (Leers) Coss. (ventenata).

The potential of novel native plant materials for the restoration of novel ecosystems

Elementa: Science of the Anthropocene, 2015
Extensive ecological change has been sustained by many dryland ecosystems throughout the world, resulting in conversion to so-called novel ecosystems. It is within such ecological contexts that native plant materials destined for ecological applications ...
