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. […]
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 […]
Learning about plant immune systems is one of the first steps toward finding ways to improve their defenses against pathogen attack. The difficulty is that, much like the immune system found in animals, the processes involved are highly complex and also completely different from other kingdoms of life. Finding out about the human immune system […]
Drought continues to be a primary driver of famine and crop loss around the world, with the accompanied water shortages not only affecting food production, but also drinking water availability. It is predicted that, by 2025, over two and a half billion people will be facing those sort of water shortages, especially as the effects […]
Nutrition and a sufficiently rounded diet of vitamins and minerals is key to remaining healthy. This is true for every person in the world. Unfortunately, there are many, billions even, that lack critical nutrients in their diets. This is often due to a combination of poverty, location, climate, and a societal and cultural focus on […]
Vitamin deficiencies plague practically every civilization in the world. Even in countries that are well-off, members of the population still have to watch their food intake and ensure that they are consuming an array of foods in order to meet their needs. Governments and food producers often supplement this by adding necessary vitamins into most […]
Temperature is something we worry about in our lives all the time. What temperature is it outside so you know what to wear and what are the conditions going to be in coming days or weeks. Farmers have to worry about this as well, as excessive periods of heat or cold snaps can prove damaging […]
Evolution isn’t perfect. It is not a controlled or directed system, but instead just a result of adaptation to one’s environment through trial and error. Over a long period of time and generations, this trends toward organisms with better traits suited for their environment, because those with less suited traits from random mutations when born […]
When dealing with fungi, it is never just the organism itself that is the problem, but also the many mutualistic relationships it has in the soil. In some cases, those relationships are antagonistic and can be used against fungi that attack crops, such as by using specialized mycoviruses. But even in the cases where the […]
