The Arabidopsis lue1 mutant defines a katanin p60 ortholog involved in hormonal control of microtubule orientation during cell growth.

Key Points

• The Arabidopsis lue1 mutant shows disrupted microtubule orientation during cell growth, impacting development.
• Key findings indicate that this mutant affects hormonal control, crucial for microtubule organization.
• Observational analysis of the lue1 mutant demonstrates its role as an ortholog of katanin p60 in plants.
• These insights may enable better understanding of cellular growth mechanisms in plants across varied environments.
