Significant advances in the cell biology of plant-microbe interactions have been
achieved recently, to a large extent based on new technical approaches such as the use of
fluorescent protein tags in model plants exploited in conjunction with available genetic
resources. They have highlighted the pivotal role played by epidermal cells as the first site at
which direct cell-to-cell contact takes place between the plant and microbes it may host. Here,
we compare the cellular aspects of early biotrophic interactions with symbiotic and pathogenic
microbes and evaluate the hypothesis that their hosting by plant cells share common traits
related to the necessity of preserving host-cell integrity. The cellular events that accompany
cell entry by the different biotrophs are divided into three categories, depending on whether the
cellular changes are triggered by diffusible molecules, direct contact, or cell lumen
penetration. Similarities and differences mirror the nutritional and developmental strategies of
each plant-interacting organism, underlining the fact that plant cell entry represents a key
aspect in the establishment of biotrophy. |
