    The mechanical properties of individual roots and entire root systems play key roles in essential root functions such as water and nutrient acquisition, defense against soil microorganisms, and plant anchorage. However, relatively few studies have quantified the mechanics (e.g., stiffness and strength) of individual and entire root systems, or explored the link between root mechanics and root functions. This limitation is likely due to a lack of standardized methods for quantifying root mechanical properties, and has created a gap in our understanding of how root mechanical traits contribute to root functions. To date, most of our knowledge comes from studies in maize, where mechanical failure (i.e., root lodging) has detrimental impacts on crop yield. Here, we review the importance of root mechanics for maize production and discuss methods used to measure individual and entire root system mechanics.

    Brace roots (roots developing from aerial stem nodes) are a type of adventitious root that develop from aboveground stem nodes in many monocots. Brace roots may remain aerial or penetrate the soil as they perform root functions such as anchorage and resource acquisition. Although brace root development in soil or aerial environments influences function, a lot is still unknown about how their anatomy, architecture and development contributes to their function. This article summarizes the current state of knowledge on brace roots.

    Plants must be able to sense and respond to mechanical stresses encountered throughout their lifespan. The MscS-Like (MSL) family of mechanosensitive ion channels is one mechanism to perceive mechanical stresses. In maize, brace roots emerge from stem nodes above the soil and some remain aerial while some grow into the soil. We tested the hypothesis that MSL gene expression is higher in subterranean brace roots compared to those that remain aerial. However, there was no difference in MSL expression between the two environments. This work sets the foundation for a deeper understanding of MSL gene expression and function in maize.
