General Information

General Information Comment Organism
malfunction apy2 single knockout roots show increased skewing compared with wild-type roots when grown on phytagel Arabidopsis thaliana
malfunction the primary roots of seedlings overexpressing APY1 show less skewing than wild-type plants. Plants suppressed in their expression of APY1 show more skewing than wild-type plants. The primary roots of apy1 single knockout (APY1 KO) seedlings (Ws background) exhibit increased rightward skewing and have an HGI that is significantly higher than that of wild-type roots. The apy1 single knockout roots show increased skewing compared with wild-type roots when grown on phytagel. Treatment of R2-4A seedlings with estradiol induces 70% suppression of APY1 expression in the null background of APY2 and results in shortened roots with swollen root tips. Apy1 mutant roots show altered cell file rotation. Phenotypes, overview Arabidopsis thaliana
physiological function modulation of root skewing in Arabidopsis thaliana by apyrases and extracellular ATP. Skewing is induced by touch stimuli which the roots experience as they grow along the surface. Touch stimuli also induce the release of extracellular ATP (eATP) into the plant's extracellular matrix, and two apyrases (NTPDases) in Arabidopsis thaliana, APY1 and APY2, can help regulate the concentration of eATP. Exogenous application of ATP or ATPgammaS also increases skewing in wild-type roots, which can be blocked by co-incubation with a purinergic receptor antagonist. APY1 and, to a lesser extent, APY2 help control root skewing in Arabidopsis thaliana, and application of extracellular nucleotides also affects this directional growth response of roots. Treatment with ATP and ATPgammaS increases root skewing. Blocking auxin transport with 1-N-naphthylphthalamic acid (NPA) also increases root skewing Arabidopsis thaliana
