Poaceae species in about 771 genera that are classified into 12 subfamilies. See the full list of Poaceae genera. Grasses are, in human terms, perhaps the most economically important plant family. Their economic importance stems from several areas, including food production, industry, and lawns. They have been grown as food for domesticated animals for up to 6,000 years and the grains of grasses such as wheat, rice, maize (corn) and barley have been the most important human food crops. Grasses are also used in the manufacture of thatch, paper, fuel, clothing, insulation, timber for fencing, furniture, scaffolding and construction materials, floor
History of model organisms had been until then invisibly killing tobacco plants across England. It was Stanley who would accomplish this task first by changing the pH to one a more acidic one. In doing so he was able to conclude that the virus was either a protein or closely related to one, thus benefiting experimental research. There are very important reasons why these new, much smaller organisms such as the Tobacco Mosaic Virus and "E. coli" made their way into the molecular biologists’ laboratories. Organisms like "Drosophila" and "Tribolium" were much too large and too complex for the simple quantitative experiments that men
