The plant can be so severely deprived of the element that it exhibits abnormalities in its growth, development, or reproduction-that is, its “performance”-in comparison with plants not so deprived. Plants are grown with the element of interest omitted from the formulation of the culture medium...
Plants and microbes communicate to collaborate to stop pests, scavenge nutrients, and react to environmental change. Microbiota consisting of thousands of species interact with each other and plants using a large chemical language that is interpreted by
This happens primarily because the growing season and, therefore, the reproduction of pathogens and pests are long or continuous, i.e., it is not interrupted by a cold winter period that normally limits reproduction and, usually, destroys and reduces the amount of inoculum available for the ...
