KATANIN is required for the formation of complete preprophase bands and subsequent division positioning in two asymmetric divisions of the maize stomatal complex.

Abstract excerpt

Microtubule dynamics underpin cell division, movement and growth in eukaryotic organisms. KATANIN p60 is a microtubule-severing protein that promotes proper cell elongation and division. In Zea mays (maize), p60 is encoded by two genes, Discordia3a (Dcd3a) and Dcd3b. Here we refer to maize dcd3a dcd3b double mutants as p60 mutants. In plants, division positioning is initiated in late G2 via the formation of a...
