Interactions between hosts and their pathogens are numerous and come in so many forms that we continue to categorize them to this day. A unique example often seen in insects is the capability known as polyphenism, where two or more different phenotypes, or physical traits, can emerge from the same genome. This is commonly seen […]
Once upon a time, scientists thought genetics and genomes were fairly straightforward. A gene encodes a protein and that protein carries out the actions that cause physical, metabolic effects and even phenotypic effects visible to others. It was a direct and simple system, a functional way for something formed through natural selection to be built. […]
Some pathogens are content to focus on their one host and live in their niche of evolutionary propagation. They go about their ongoing generational fight to one-up their host, just as their host works to outperform and prevent infection by the pathogen. Occasionally, one of these sorts of pathogens will branch off and appropriate one […]
Tracking plant pathogens is no simple matter. Due to their possible environmental hidey holes being in the soil, the air, other plants, or the host plants themselves lying dormant, any and every possibility must be accounted for. And the triggers that begin active pathogenicity and harm to the plant is connected to a convoluted system […]
