How do plant organs stay smooth—or become wrinkled? 🌱 Our paper in @currentbiology.bsky.social shows how coordinated growth direction and mechanical properties across cell layers determine whether Arabidopsis sepals remain smooth or buckle. cell.com/current-biol...

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).

Brassinosteroid controls leaf air space patterning non-cell autonomously by promoting epidermal growth Read this Research Article from our special issue #DevSIextracellular by James Fitzsimons and colleagues doi.org/10.1242/dev....
Figure 1 from the paper. A. thaliana leaves contain palisade and spongy mesophyll cells surrounded by intercellular air space. (A) Transverse section of a mature A. thaliana leaf showing palisade mesophyll (false coloured blue) and spongy mesophyll (false coloured yellow) visualised by freeze-fracture Cryo-SEM. (B,C) Palisade (B) and spongy (C) mesophyll tissue visualised with Nile red dye. Air spaces are green, cell outlines magenta. Scale bars: 100 µm.

With James Clark, he also found WOX13LC to be ancient, arising from a duplication of WOX13LA/B genes and sequence divergence in peristomate mosses. In the paper available on the link below, we present some models of PpWOX13L function and evolution. www.sciencedirect.com/science/arti...
