Corn plants are susceptible to infection by fungi such as Aspergillus flavus that have the potential to produce several types of mycotoxins, one of the most potent ones known to exist is aflatoxin. Since aflatoxin contaminated corn must be destroyed, causing annual monetary losses in billions of dollars, it would be helpful to detect the presence of aflatoxin producing fungi at pre-harvest and pre-planting stages. To this end,...

The domestication of crops leads to profound changes on plant phenotypes, yet its effects on floral traits mediating plant-pollinator interactions remain poorly understood. Floral volatile organic compounds (VOCs) play a crucial role in pollinator attraction by signaling the presence and quality of available floral resources. Here, we characterize VOC composition in Cucurbita , a genus containing multiple wild and domesticated...

Volatile organic compounds are important chemical signals involved in plant-insect interactions. In recent decades, volatiles have been used in many agricultural applications to help control crop pests, but fewer applications have been developed for belowground pests despite volatile signaling and olfactory cues being crucial for orientation and communication of belowground organisms. Volatile signals also depend heavily on so...

Cannabis and its major constituents, Δ 9 -tetrahydrocannabinol (THC) and cannabidiol (CBD), are being widely used to treat sleep disturbances. However, THC can cause acute cognitive and psychomotor impairment and there are concerns that driving and workplace safety might be compromised the day after evening use. Here, we examined possible ‘next day’ impairment following evening administration of a typical medicinal cannabis oi...
