Root hair growth dramatically expands the root surface area, thus facilitating water and nutrient uptake. Until recently, the molecular mechanism underlying root hair growth was unknown. Recent studies have revealed that the transcription factor ROOT HAIR DEFECTIVE 6 LIKE 4 (RSL4) coordinates hormonal, environmental, and developmental factors to trigger polar growth.

Lotus japonicus-ROOT HAIR LESS1-LIKE1 (LRL1) of Arabidopsis thaliana encodes a basic helix-loop-helix (bHLH) transcription factor (TF) involved in root hair development. Root hair development is regulated by an elaborate transcriptional network, in which GLABRA2 (GL2), a key negative regulator, directly represses bHLH TF genes, including LRL1 and ROOT HAIR DEFECTIVE6 (RHD6). Although RHD6 and its paralogous TFs have been shown to connect downstream to genes involved in cell morphological events such as endomembrane and cell wall modification, the network downstream of LRL1 remains elusive.

Vitamin D is essential for healthy skeletal growth and is increasingly recognised for its role in chronic disease development, inflammation and immunity. 25-hydroxyvitamin D (25(OH)D) concentrations are an indicator of vitamin D status and are normally analysed in plasma or serum samples in clinical settings, while archaeological studies rely on the identification of skeletal markers of vitamin D deficiency, such as rickets. Here, we determined 25(OH)D concentrations in hair specimens ('locks') that had been sampled close to the root, aligned by cut end, and sliced into sequential segments from participants (n = 16), from Aberdeen, Scotland, using a modified protocol designed to minimise sample size.

Root development is a complex process involving phytohormones and transcription factors. Our previous research has demonstrated that is significantly expressed in Bok choy roots under salt stress, and heterologous expression of increases salt tolerance and promotes root development in transgenic . However, the precise molecular mechanisms by which BcWRKY33A governs root development remain elusive.

Jasmonate (JA), a key plant hormone, regulates various aspects of plant development and stress responses, primarily through the degradation of canonical jasmonate-ZIM domain (JAZ) proteins by the SCF complex. While JAZ8, a non-canonical JAZ protein lacking the degron signal, has been shown to repress JA responses, the mechanism by which JA inhibits JAZ8 activity remains unclear. Here, we demonstrate that Arabidopsis ethylene response factor 114 (ERF114), ERF115, and ERF109 regulate JA signaling through interacting with JAZ8.
