AI Article Synopsis
- - The development of new plant cultivars that require less fertilizer and water is a significant challenge, emphasizing the need for innovative methods and technologies to study plant traits.
- - Global research efforts are centered on high-throughput phenotyping and understanding root traits, but they often overlook the importance of root hairs (RHs) in plant health and performance.
- - This review focuses on the role of root hairs in plant hydration and nutrient acquisition, highlighting genetic data that links RH traits with overall plant growth and yield.
Article Abstract
Breeding new cultivars allowing reduced fertilization and irrigation is a major challenge. International efforts towards this goal focus on noninvasive methodologies, platforms for high-throughput phenotyping of large plant populations, and quantitative description of root traits as predictors of crop performance in environments with limited water and nutrient availability. However, these high-throughput analyses ignore one crucial component of the root system: root hairs (RHs). Here, we review current knowledge on RH functions, mainly in the context of plant hydromineral nutrition, and take stock of quantitative genetics data pointing at correlations between RH traits and plant biomass production and yield components.
