Cell-to-cell communication is a fundamental mechanism for coordinating developmental and physiological events in multicellular organisms. Heterotrimeric G proteins are key molecules that transmit extracellular signals; similarly, CLAVATA signaling is a crucial regulator in plant development. Here, we show that Arabidopsis thaliana Gβ mutants exhibit an enlarged stem cell region, which is similar to that of clavata mutants. Our genetic and cell biological analyses suggest that the G protein beta… CONTINUE READING
