The arrangement of wall microtubules (MTs) in Pisum sativum roots was viewed immunofluorescently using cryosectioning. Most cells in the tip region of pea roots (0-2 mm from tip) had wall MTs arranged transversely to the root axis. In the region elongating at a higher rate (2-4 mm), wall MTs of epidermal, cortical and stelar cells were all transversely arranged. In the region of about 5 mm from the tip, in which cell elongation had already ceased, wall MTs in cortical cells changed from a transverse to an oblique arrangement in relation to the root axis. Some cells had a crossed arrangement of wall MTs, which was interpreted as representing two sets of unidirectional, oblique wall MTs in opposite cell cortices of a single cell. This change was completed within a region of 1-mm width. Since roots elongated at a rate of 0.6 mm h^<-1> it means that the arrangement of wall MTs changed within 2 h. An oblique arrangement of wall MTs was also observed in stelar cells. As the cells aged, the oblique arrangement tended to change to a steeper or even a longitudinal one.
