Gene : RALF23 A. thaliana

DB identifier  ? AT3G16570 Secondary Identifier  ? locus:2089323
Name  ? rapid alkalinization factor 23 Brief Description  rapid alkalinization factor 23
TAIR Computational Description  rapid alkalinization factor 23;(source:Araport11)
TAIR Curator Summary  Encodes RALF23, a member of a diversely expressed predicted peptide family showing sequence similarity to tobacco Rapid Alkalinization Factor (RALF), and is believed to play an essential role in the physiology of Arabidopsis. Consists of a single exon and is characterized by a conserved C-terminal motif and N-terminal signal peptide. RALF23 is significantly downregulated by brassinolide treatment of seedlings. Overexpression of AtRALF23 impairs brassinolide-induced hypocotyls elongation, and mature overexpressing plants are shorter and bushier. RALF23 overexpression produces slower growing seedlings with roots that have reduced capacity to acidify the rhizosphere.

Type Comment Proteins
RLF23_ARATH developmental stage In very young seedlings, confined to the tips of the cotyledons. Later expressed in the cotyledon vasculature and petiole. Present in the tip of emerging leaves. In mature leaves, observed in the vasculature.
RLF23_ARATH function Cell signaling peptide that may regulate plant stress, growth, and development. Mediates a rapid alkalinization of extracellular space by mediating a transient increase in the cytoplasmic Ca(2+) concentration leading to a calcium-dependent signaling events through a cell surface receptor and a concomitant activation of some intracellular mitogen-activated protein kinases (By similarity). Negatively regulates brassinolide (BL)-mediated signaling pathway (e.g. BL-induced hypocotyl elongation and branching limitation) (PubMed:19473327).
RLF23_ARATH similarity Belongs to the plant rapid alkalinization factor (RALF) family.
