Gene Details:

• Gene ID: Zm00001eb241060
• Gene Symbol: Bv1
• Gene Name: brevis plant1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Maize brevis plant1 (Bv1) mutants, first identified over 80 years ago, strongly resemble brachytic2 mutants that have shortened internodes, short internode cells, and are deficient in auxin transport.
• We found that an inositol polyphosphate 5-phosphatase orthologue of the rice gene dwarf50 was the molecular basis for the Bv1 phenotype, implicating auxin-mediated inositol polyphosphate and/or phosphoinositide signalling in stem elongation.
• Genes misregulated in Bv1 mutants included genes important for cell wall synthesis, transmembrane transport, and cytoskeletal function.
• Suitable Bv1 alleles are candidates for future crop improvement.
• These attributes suggest that breeding could utilize Bv1 alleles to increase crop grain yields.
