Endoplasmic microtubules configure the subapical cytoplasm and are required for fast growth of Medicago truncatula root hairs.

Abstract

To investigate the configuration and function of microtubules (MTs) in tip-growing Medicago truncatula root hairs, we used immunocytochemistry or in vivo decoration by a GFP linked to a MT-binding domain. The two approaches gave similar results and allowed the study of MTs during hair development. Cortical MTs (CMTs) are present in all developmental stages… (More)
