Novel roles for Arabidopsis dynamin-related proteins DRP1A and DRP2B in resistance against fungal infection.

Arabidopsis DYNAMIN-RELATED PROTEIN1A (DRP1A) and DRP2B are large GTPases that function together in endocytosis for effective cytokinesis, cell enlargement and development. A recent study shows that these DRPs contribute to ligand-induced endocytosis of the immune receptor FLAGELLIN SENSING2 (FLS2) to modulate flg22-immune signaling, and they are required for immunity against pv. bacteria.
