title: sparse inflorescence1, barren inflorescence1 and barren stalk1 promote cell elongation in maize inflorescence development.
abstract: The sparse inflorescence1 (spi1), Barren inflorescence1 (Bif1), barren inflorescence2 (bif2), and barren stalk1 (ba1) mutants produce fewer branches and spikelets in the inflorescence due to defects in auxin biosynthesis, transport, or response. We report that spi1, bif1, and ba1, but not bif2, also function in promoting cell elongation in the inflorescence.
