Plant-microbe interactions. Affairs of the plant: colonization, intolerance, exploitation and co-operation in plant-microbe interactions.

Plants are the primary carbon source for nearly all terrestrial non-photosynthetic organisms, including ourselves. Many species seek to tap this photosynthate, and plants are continuously resisting their strenuous and intimate advances. The review articles in this issue of Curretzt Opittiotr itt Platrt Biology address recent progress in several relationships, some more polite and considerate than others, between plants and other organisms. (For reasons of space, most plant herbivore interactions were not addressed.)
