This study found that while a tip-focused calcium gradient influences localized growth in root hairs and pollen tubes, it is not the primary determinant of growth direction in root hairs of Arabidopsis thaliana.

This review discusses the potential roles of calcium in the regulation of pluripotent and tissue-specific stem cells but reports no new experimental results, highlighting areas for future research.

This study found that salinity stress in Arabidopsis thaliana root hairs may inhibit hair extension through changes in the tip-focused Ca(2+) gradient, while cytosolic pH remains unaffected.

This study concluded that CNGC14 is a calcium-permeable channel crucial for polarized tip growth in Arabidopsis root hairs, but other channels may also influence the observed calcium influx.

This study reviews the complex keratinization process in the epidermis, detailing how various factors regulate keratinocyte differentiation and emphasizing the importance of understanding this process for the pathogenesis of skin disorders like ichthyoses and psoriasis.
