Study reports that APY1 and, to a lesser extent, APY2 help control root skewing, the right-slanted growth of roots, in Arabidopsis.
Title: Modulation of Root Skewing in Arabidopsis by Apyrases and Extracellular ATP.

APY1, APY2, and extracellular ATP play important roles in the signaling steps that link biotic stresses to plant defense responses and growth changes.
Title: Apyrase suppression raises extracellular ATP levels and induces gene expression and cell wall changes characteristic of stress responses.

low levels of apyrase chemical inhibitors can induce stomatal opening in the dark, while apyrase enzyme blocks abscissic acid-induced stomatal closure.
Title: Effects of chemical inhibitors and apyrase enzyme further document a role for apyrases and extracellular ATP in the opening and closing of stomates in Arabidopsis.

Suppression of APY1/APY2 expression results in a significant inhibition of polar auxin transport in Arabidopsis hypocotyls and roots.
Title: Role for apyrases in polar auxin transport in Arabidopsis.

AtAPY1 and AtAPY2 are Golgi-localized nucleotide diphosphatases and are likely to have roles in regulating UDP/GDP concentrations in the Golgi lumen.
