Abstract excerpt
MAIN CONCLUSION: Our results show that RIC4 and the Arp2/3 complex function largely independently in the control of pavement cell shape. Genetic analyses indicate that they act in parallel rather than in one signaling cascade. We further demonstrate that RIC4 functions as a negative regulator of lobe formation, as its loss increases cell shape complexity whereas its overexpression increases cell circularity....
