AI-generated Abstract

This study investigates the relationship between cortical microtubule organization and cell expansion in the roots of Arabidopsis thaliana mutants deficient in primary cell wall components. It finds that during cell expansion, cortical microtubules align transversely, facilitating cellulose microfibril deposition. In contrast, mutant lines exhibit a shift to random microtubule orientation due to impaired cellulose synthesis, leading to inhibited cell expansion. Consequently, this research elucidates the bidirectional influence of microtubule organization on cell wall properties and vice versa, highlighting critical signaling pathways that warrant further exploration.
