Abstract
Plant roots: new challenges in a changing world
Highlights
As research on roots intensifies due to the growing realization that a better understanding of their function and genetics offers important strategies for tackling the global challenge set by increased population, climate change, and food security, it is important to present new developments in the area
The authors show that the model predicts root traits with high accuracy in a diverse panel of Brasica rapa, and suggest that the model will be useful in identifying genotypes with efficient root systems in phenotyping screens even if they have incomplete image data
The results suggest that, while the mutant showed most of the typical responses to drought, they appear to have less of the responses associated with root to shoot stress signalling, suggesting a role for root hairs in drought perception and/or signalling
Summary
As research on roots intensifies due to the growing realization that a better understanding of their function and genetics offers important strategies for tackling the global challenge set by increased population, climate change, and food security, it is important to present new developments in the area. A related review by Shabala et al (2016) focuses on the role of membrane transporters in the sensing and response to soil-based plant stresses first experienced by the root—those of drought, salinity, and flooding, emphasizing specific genes with promise for conferring tolerance.
