How fast do plants actually grow? And which growth processes matter most for organ size?
We dived into 176 papers, extracted and re-analyzed the data so you don’t have to!

Have you ever wondered how microtubules withstand and respond to mechanical stress in cells?
Here we show by in vitro reconstitution assays that MAP65-1 and PRC1 promote microtubule nucleation on existing lattices, especially on those with structural irregularities linked to mechanical stress.

Despite their high rigidity, microtubules (MTs) dynamically bend and buckle in cells. MT-self repair is inherent to their metastable nature, but it remains unclear whether just inherent repair mechanisms are sufficient to maintain MT integrity🧵 (1/9)
