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

We have another recent paper about leaves buckling due to uneven growth across the width of the leaf: doi.org/10.1371/journal.pbio…

Growth-rate coordination across the width of a leaf preserves its flatness

The growth of plant leaves is highly dynamic and should be coordinated, but the mechanisms that preserve leaf flatness remain unclear. This study shows that global coordination of growth across the...

These principles should hold to other plant organs. The constraints of the edges of the organ are likely to be important. kanadi1/2 double mutant leaves appear to have similar buckles. However, there are additional ways that plant organs can buckle if growth is uncoordinated.

The Cornell Chronicle highlighted our recent Current Biology paper, showing how cell growth and tissue mechanics work together to shape developing sepals—and how these principles could help engineer living materials. news.cornell.edu/stories/202…

Wrinkled or smooth? Cell growth mechanics determine shape of plant organs | Cornell Chronicle

This discovery could help engineer living materials into different forms, such as the custom of growing bridges from roots in India, and breeding kale so it’s smooth instead of crinkly.

Deeply saddened by the passing of Meng. Heartbroken to lose a candid, generous friend and colleague. Plant science lost a brilliant mind, but I will remember Meng as a kind soul who inspired those around him. Rest in peace. You are sorely missed. 💔

Plant cells have their own language, & #HHMIInvestigator Keiko Torii has spent 30 yrs decoding it. Her team's new work on the signals guiding stomatal development — & how plants balance that with pathogen defense — could help develop more resilient crops: bit.ly/4hFvOIy

Diagram of SAM with zones labelled. SAM cells undergo a transient high-growth and high-proliferation state, especially around the putative central zone during doming. Next question is are all cell-cycle states also spatially and temporarally reorganise?

How does a growing leaf stay flat? 🍃 Our new paper in @PLOSBiology shows that maintaining leaf flatness requires growth-rate coordination across the width of the leaf blade—not just between the top and bottom surfaces. journals.plos.org/plosbiolog…
