The mammalian reoviruses (serotype 1, strain Lang and serotype 3, strain Dearing) differ in their sensitivity to digestion by chymotrypsin. We have found that the M2 double-stranded RNA (dsRNA) genome segment (encoding the micro1C outer capsid polypeptide) is responsible for this property. In addition to determining response to protease treatement in vitro, we have found that the M2 genome segm...

In a single experiment, field-grown Louisiana sugarcane was augmented with phytoparasitic nematodes, treated with aldicarb, or left untreated in both weedy and weed-free habitats to study interactions among nematodes, weeds, sugarcane, and sugarcane free amino acid titers. Aldicarb reduced three of the six phytoparasitic nematode genera at various times during the two growing seasons and was as...

Field trials of transgenic crops may result in unintentional transgene flow to compatible crop, native, and weedy species. Hybridization outside crop fields may create novel forms with potential negative outcomes for wild and weedy plant populations. We report here the outcome of large outdoor mesocosm studies with canola (Brassica napus), transgenic canola, a sexually compatible weed B. rapa, ...

Weedy sunflower, Helianthus annuus L. is an economically very important, invasive species widely distributed in many regions of the world, especially areas where sunflower hybrids tolerant to some als-inhibiting herbicides are intensively cultivated. The discovery and development a new technology cultivated increased emergence resistant biotypes due high selection pressure spontaneous hybridisa...

Coral reefs are increasingly threatened by global and local anthropogenic stressors such as rising seawater temperature, nutrient enrichment, sedimentation, and overfishing. Although many studies have investigated the impacts of local and global stressors on coral reefs, we still do not fully understand how these stressors influence coral community structure, particularly across environmental g...
