About this Research Topic
From an ecological perspective, responses to the environment are certainly adapted to the niche in which a plant lives, whether it be rapid growth in conducive conditions or to sustained growth in adverse conditions. How do different species regulate and integrate environmental growth responses? How do these responses compare in r-selected species (such as Arabidopsis), which are adapted for rapid invasive growth in favorable conditions, and K-selected species (such as poplar), which are adapted to highly efficient growth in stable conditions? Do these strategies have any clear differences? Can we find clues by comparing characteristic responses of K- and r-selected species to abiotic stresses on cellular scales? To what extent do the responses of either group reflect a general response to stress, common responses to linked conditions or highly specialized responses to specific signals?
This Research Topic will gather a group of studies which focus on the response of roots to specific environmental stresses, and aim to answer these questions by comparing responses to specific environmental conditions between species, examining to what extent they have similarities on a molecular level. This research topic therefore aims at summarizing the progress in the field, focusing on the sensing and the integration of soil stimuli by plant roots.
