TMO5 orchestrates organ patterning in plant shoots This Research Highlight showcases work by Abdul Kareem, Carolyn Ohno and Marcus Heisler (@heisler-lab.bsky.social): journals.biologists.com/dev/article/...
TMO5 promotes PIN1 polarity convergence and organogenesis independent of MP. (A-C) Activation of PIN1-CFP expression (intensity-based colouring; the look-up table displays the signal intensity range), convergence formation and organ outgrowth in mp mutant shoot meristems after clonal activation of TMO5-2YPET (green). Panels A and B show the same meristem over time, whereas panel C presents a representative meristem (n=27). (D,E) Flower formation on mp pin-like inflorescence meristem following clonal activation of TMO5-2YPET (n=10). (F-J) No effect on PIN1 localization or organ outgrowth in mp mutant meristems with local activation of DOF5.8-YPET (F-H; n=12) or TMO6-YPET (I,J; n=15). Inset in G shows the meristem with the PIN1-CFP channel alone for clearer visualization. (K-M) Time-lapse images of the same mp mutant meristem region from 1 to 6 days after TMO5 clone formation, showing PIN1-GFP polarization in neighbouring cells towards the clones. The dashed box in K marks the area shown in L and M. Arrows indicate polarity (n=13). (N) PIN1-GFP polarization towards a TMO5 clone lacking organ outgrowth (n=9). (O,P) PIN1-CFP convergence in epidermal TMO5-expressing clones and polarized PIN1 in neighbouring cells in the mp mutant meristem at two time points of the same clones. Lower panels show longitudinal sections. Arrows indicate polarity; arrowhead in P marks sub-epidermal PIN1 expression (n=24). (Q) Two distinct organ outgrowths with epidermal PIN1 convergence induced by epidermal (left) or sub-epidermal (right) TMO5 clones. Lower panels show longitudinal sections. White arrowhead marks PIN1 activation in sub-epidermal cells; orange arrowhead marks sub-epidermal TMO5 clones. Dashed line marks the outgrowth boundary (n=5). Scale bars: 20 µm (A-C,F,G,I-Q); 1 mm (D,E,H).
