As sessile organisms, plants have developed adaptation mechanisms for changing environments. To deal with environmental problems facing the world today such as global warming and desertification, understanding plant adaptation mechanisms to environmental stresses is essential. Thus, researchers have been investigating the mechanisms of plant adaptation from various angles. This JPR Symposium entitled “Toward unveiling plant adaptation mechanisms to environmental stresses” reviews two different facets of plant adaptation mechanisms.

Shibata and Sugimoto (2019) review how environmental signals are transduced and altered root hair development. They point out that a gene regulatory network (GRN) consisting of transcription factors enables plasticity during root hair development. Especially, they claim that a GRN enables the plant to respond accordingly to multiple environmental signals. Shibata and Sugimoto (2019) also introduce the RSL4-GTL1 module as the core GRN for root hair development based on their recent findings (Shibata et al. 2018).

Scharwies and Dinneny (2019) broadly summarize current knowledge regarding water transport, perception and response in plants. First, they explain from a biophysical perspective how water moves from the soil through the plant and eventually evapotranspirates into the atmosphere. Secondly, they describe systemic and local responses to water deficit gleaned from a broad array of studies ranging from classical observations by Charles Darwin to the latest publications. Finally, Scharwies and Dinneny (2019) discuss putative water sensing mechanisms, particularly how water-availability changes are transduced as chemical signals.

For future research, we emphasize the importance of further understanding systemic responses as well as local responses, both of which underlie harmonized and flexible plant response toward continuously changing environmental conditions. In addition to focusing on an individual study, it will be necessary to integrate pieces of findings to reveal the whole picture of plant adaptation mechanisms, which will accelerate providing solutions for coping with global-scale environmental problems.
