Deciphering the biological processes in root hairs required for N-self-fertilizing cereals

In this review, Simon Pree et al. discuss the latest knowledge on the role of root hairs and root hair exudation in plant-microbiome interactions and outline how this knowledge can be applied to develop cereals better equipped to benefit from N2 fixing bacteria. Further, the review describes non-destructive methods for the study of root hair growth and discusses their limitations.

Harnessing root-soil-microbiota interactions for drought-resilient cereals 

This review by Gholizadeh et al. discusses how interactions between roots, soil and microbiota can improve the soil environment and cereal plant fitness under drought and suggests a roadmap for harnessing the benefits of these interactions for drought-resilient cereals.
