Constitutive redox and phosphoproteome changes in multiple herbicide resistant Avena fatua L. are similar to those of systemic acquired resistance and systemic acquired acclimation.

Plants are routinely confronted with numerous biotic and abiotic stressors, and in response have evolved highly effective strategies of systemic acquired resistance (SAR) and systemic acquired acclimation (SAA), respectively. A much more evolutionarily recent abiotic stress is the application of herbicides to control weedy plants, and their intensive use has selected for resistant weed populations that cause substantial crop yield losses and increase production costs. Non-target site resistance (NTSR) to herbicides is rapidly increasing worldwide and is associated with alterations in generalized stress defense networks.

Proteomic and biochemical assays of glutathione-related proteins in susceptible and multiple herbicide resistant Avena fatua L.

Extensive herbicide usage has led to the evolution of resistant weed populations that cause substantial crop yield losses and increase production costs. The multiple herbicide resistant (MHR) Avena fatua L. populations utilized in this study are resistant to members of all selective herbicide families, across five modes of action, available for A.

Intensive herbicide use has selected for constitutively elevated levels of stress-responsive mRNAs and proteins in multiple herbicide-resistant Avena fatua L.

Background: Intensive use of herbicides has led to the evolution of two multiple herbicide-resistant (MHR) Avena fatua (wild oat) populations in Montana that are resistant to members of all selective herbicide families available for A. fatua control in US small grain crops. We used transcriptome and proteome surveys to compare constitutive changes in MHR and herbicide-susceptible (HS) plants associated with non-target site resistance.

Predicting Developmental Timing for Immature Canada Thistle Stem-Mining Weevils, Hadroplontus litura (Coleoptera: Curculionidae).

Predictions of phenological development for insect biological control agents may facilitate post-release monitoring efforts by allowing land managers to optimize the timing of monitoring activities. A logistic thermal time model was tested to predict phenology of immature stem-mining weevils, Hadroplontus litura F. (Coleoptera: Curculionidae), a biological control agent for Canada thistle, Cirsium arvense L.

Deficits in emotion regulation mediate the relationship between childhood abuse and later eating disorder symptoms.

The present study examined the relationship of child maltreatment to both emotion dysregulation and subsequent eating pathology. In an effort to extend previous research, the authors examined the unique impact of childhood emotional abuse (CEA) on emotion dysregulation and eating disorder (ED) symptoms while controlling for the effects of sexual and physical abuse. Structural equation modeling was utilized to simultaneously examine the effects of all three abuse types on multiple dependent variables as well as examine whether deficits in emotion regulation mediated the relationship between abuse and eating pathology.

Attributions of responsibility in a child sexual abuse (CSA) vignette among respondents with CSA histories: the role of abuse similarity to a hypothetical victim.

Previous research suggests that similarity to a victim may influence attributions of responsibility in hypothetical child sexual abuse scenarios. One aspect of similarity receiving mixed support in the literature is respondent child sexual abuse history. Using a sample of 1,345 college women, the present study examined child sexual abuse history, similarity to victim, and attributions of responsibility to a hypothetical victim, family member, and perpetrator in a child sexual abuse vignette.
