additional information | mutant plants homozygous for T-DNA-disrupted PIP5K3 alleles are compromised in root hair formation. Root hair-specific PIP5K3 overexpression results in root hair deformation and loss of cell polarity with increasing accumulation of PIP5K3 transcript. An N-terminal domain containing membrane occupation and recognition nexus repeats, which is not required for catalytic activity, is essential for the establishment of root hair growth. Transient heterologous expression of full-length PIP5K3 in Nicotiana tabacum pollen tubes increases plasma membrane association of a phosphatidylinositol 4,5-bisphoshate-specific reporter | Arabidopsis thaliana |
