Some bacteria produce organic acids that directly attack parent material, breaking it down and releasing plant nutrients. Others decompose organic litter (debris) to form humus (nutrient-rich organic matter). A third group of bacteria inhabits the root systems of plants called legumes. These ...
For example, some kinds of soil bacteria take nitrogen(氮)from the air and make it into a form that plants can use. The plants hold the nitrogen in their roots. Legumes (豆科植物)are especially good at this nitrogen﹣fixing. Then any crops that share the same space with the legumes can...

Crh proteins catalyze crosslinking of chitin and glucan polymers in fungal cell walls. Here, we show that the BcCrh1 protein from the phytopathogenic fungus Botrytis cinerea acts as a cytoplasmic effector and elicitor of plant defense. BcCrh1 is localize
