Trypsinogen Pro-Region as a Molecular Scaffold for the Design of Competitive Peptide Inhibitors of Trypsin-Like Proteases. [PDF]

Arch Insect Biochem Physiol
Rational design of the trypsinogen pro‐region generated the peptide inhibitors GORE3, GORE4, and GORE5. Computational screening and enzyme kinetics demonstrated competitive inhibition of trypsin‐like proteases, with GORE5 showing the highest experimental potency and supporting pro‐region‐derived peptides as promising protease‐targeting molecules ...

Evidence of Rapid Evolution in Herbivory Defense Responses With Conserved Trade-Offs in Populations of <i>Medicago polymorpha</i>. [PDF]

Ecol Evol
This study uses a historical invasion by Medicago polymorpha (Burr Clover) to test the predictive power of the Shifting Defense Hypothesis (SDH) by investigating variation in plant defenses to herbivorous insects. We compared the feeding preferences of a generalist and a specialist herbivore on native and invasive populations of M.

Insect-resistant soybean genotypes accumulate rutin and its O-methylated derivative narcissin, a more potent flavonol targeting Anticarsia gemmatalis digestive and detoxification enzymes and reducing larval survival. [PDF]

J Sci Food Agric
Abstract BACKGROUND Soybean underpins Brazil's agricultural, yet its sustainability is threatened by lepidopteran pests such as Anticarsia gemmatalis. Although insect‐resistant cultivars have long been associated with the constitutive accumulation of quercetin‐derived flavonols, the biochemical mechanisms underlying this resistance remain poorly ...

Domain III of Cry1Ac Is Critical to Binding and Toxicity against Soybean Looper (Chrysodeixis includens) but Not to Velvetbean Caterpillar (Anticarsia gemmatalis) [PDF]

Toxins, 2018
Insecticidal proteins Cry1Ac and Cry2Ac7 from the bacterium Bacillus thuringiensis (Bt) belong to the three-domain family of Bt toxins. Commercial transgenic soybean hybrids produce Cry1Ac to control the larvae of the soybean looper (Chrysodeixis ...

Cry1Ac toxin binding in the velvetbean caterpillar Anticarsia gemmatalis: study of midgut aminopeptidases N [PDF]

Frontiers in Physiology
The velvetbean caterpillar Anticarsia gemmatalis is one of the main soybean defoliators in Brazil. Currently, the main biopesticide used to control insect pests worldwide is the bacteria Bacillus thuringiensis (Bt), which produces entomopathogenic ...

Under Concurrent Drought and Herbivory, Drought Dominates Herbivory on Morpho-Physiological Responses in Soybean. [PDF]

Physiol Plant
ABSTRACT Drought and insect herbivory constantly threaten yield and productivity of crops like soybean (Glycine max). Recent advances in crop science have examined these stressors either individually or sequentially, but concurrent interactions have not been well understood.

Redox imbalance mediates entomotoxic effects of the conifer Araucaria angustifolia in Anticarsia gemmatalis velvetbean caterpillar

Cogent Food and Agriculture, 2016
The velvetbean caterpillar, Anticarsia gemmatalis is one of the most important pests of soybean crops in tropical America. By feeding on leaves, significant defoliation occurs resulting in reduced photosynthetic capacity required for plants’ maintenance ...

Homeopathic Solutions as a Tool for the Agroecological Management of Velvetbean Caterpillar

Brazilian Archives of Biology and Technology, 2023
Soybean is the main oilseed crop in the world, and one of the main challenges for its production is the Anticarsia gemmatalis management, especially in agroecological production systems.
