research ER-located Ca2+ ATPase ACA2 regulates Ca2+ cytoplasmic pool linked to root hair growth in Arabidopsis thaliana
In this study, researchers found that the efflux of calcium in root hairs of Arabidopsis thaliana, particularly through the ER-localized ACA2 and ACA7, is crucial for modulating cytoplasmic calcium signals and enabling proper root hair growth, with disruptions leading to impaired elongation.
