| Popis: | Parasitic plants are usually considered as botanical curiosities because of their shapes and colours. However, in some cases, they are proving to be terrible bioagressors in man-made ecosystems. Parasitic plants have indeed the capacity to connect intimately with other plants to exploit their resources (water, nutrients, growth regulators…) for their development. Thus, these plants are the result of an evolutionary transition from autotrophism to heterotrophism. The underlying process of this trophic exploitation, governed by a fine-tuned molecular dialogue between both partners, is an extraordinary example of adaptive plant biology operated by these parasitic organisms in the course of evolution. This transition is associated with remarkable morphological and physiological adaptations, and these adaptive strategies have led some parasitic plants to become deadly pests for crops against which no efficient control methods are yet available, especially in terms of sustainability. This chapter highlights the actual knowledge regarding the molecular aspects of these intimate and intriguing communications between host plants and parasitic plants, with a special focus on root parasitic plants. |
