ER-located Ca2+ ATPase ACA2 regulates Ca2+ cytoplasmic pool linked to root hair growth in Arabidopsis thaliana
Root hairs (RH) are excellent model systems for studying cell size and polarity since they elongate several hundred-fold their original size. Their tip growth is regulated by both intrinsic and environmental signals and is associated with the existence of a highly controlled cytoplasmic tip Ca{superscript 2} gradient, whose disruption impairs RH development. The molecular mechanisms underlying…
