Abstract
Stress tolerance pathways are protective mechanisms that have evolved to protect plant growth and increase production under various environmental stress conditions. Enhancing stress tolerance in crop plants has become an area of intense study with aims of increasing crop production and enhancing economic benefits. A growing number of studies suggest that in addition to playing vital roles in mechanical architecture and cell division, microtubules are also involved the adaptation to severe environmental conditions in plants. However, the mechanisms that integrate microtubule regulation, cellular metabolism and cell signaling in plant stress responses remain unclear. Recent studies suggest that microtubules act as sensors for different abiotic stresses and maintain mechanical stability by forming bundles. Characterizing the diverse roles of plant microtubules is vital to furthering our understanding of stress tolerance in plants.
