Gene Details:

• Gene ID: Zm00001eb123060
• Gene Symbol: ZmLBD18|ra2
• Gene Name: ramosa2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ramosa2 Encodes a LATERAL ORGAN BOUNDARY Domain Protein That Determines the Fate of Stem Cells in Branch Meristems of Maize.
• The ramosa2 (ZmLBD18|ra2) mutant of maize has increased branching with short branches replaced by long, indeterminate ones.
• ZmLBD18|ra2 is transiently expressed in a group of cells that predicts the position of axillary meristem formation in inflorescences.
• The ZmLBD18|ra2-dm allele suggests this domain is required for transcriptional activation of ra1. The ZmLBD18|ra2 expression pattern is conserved in rice (Oryza sativa), barley (Hordeum vulgare), sorghum (Sorghum bicolor), and maize, suggesting that ZmLBD18|ra2 is critical for shaping the initial steps of grass inflorescence architecture.
• Although ZmLBD18|ra2 contains a LOB domain, the phenotype is unique to maize. te1 is involved in the regulation of leaf initiation: Loss of its function causes an increase in the frequency of leaf primordia initiation and irregular internode length.
