BACILLUS THURINGIENSIS CRY1CA-RESISTANT SPODOPTERA EXIGUA LACKS EXPRESSION OF ONE OF FOUR AMINOPEPTIDASE N GENES

Bacillus thuringiensis Cry1Ca-resistant Spodoptera exigua lacks expression of one of four Aminopeptidase N genes

Abstract Background Insecticidal toxins from Bacillus thuringiensis bind to receptors on midgut epithelial cells of susceptible insect larvae.Aminopeptidases N (APNs) from several insect species have been shown to be putative receptors for these toxins.Here we report the cloning and expression analysis of four APN cDNAs from Spodoptera exigua.Resul

Rainfall-intensity effect on landslide hazard assessment due to climate change in north-western Colombian Andes

Landslides triggered by rainfall are one of the most Home Accent frequent causes of disasters in tropical countries and mountainous terrains.Recent studies show an upsurge in landslide occurrence as an expected impact of human-induced climate change.This paper presents the analysis and implementation of two different physically-based models, SHALST
