Immunoblotting analysis of TSN1/2 (TUDOR-staphylococcal nuclease protein 1/2) abundances in roots of Arabidopsis wild type Col-0 and KATANIN 1 mutants fra2 and ktn1-2. A, immunoblots probed with anti-TSN1/2 antibody. B, visualization of proteins transferred on nitrocellulose membranes. C, optical density quantification of band in A. Asterisks indicate significant differences between mutants and wild type at p ≤ 0.05 according to the Student's t test. Error bars represent standard deviations.
