General Information | Comment | Organism |
---|---|---|
evolution | origin for the vt2/vt2-like clade at least near the base of the grass family and possibly deeper within monocots | Zea mays |
malfunction | vt2 mutants have dramatic effects on vegetative and reproductive development, decrease in leaf number in vt2 mutants, reduced tassel length in vt2 mutants is likely due to reduced cell elongation. In addition to male inflorescence defects, vt2 mutants also show severe defects in the female inflorescence, absence of branches and spikelets in vt2 inflorescences. spi1/vt2 double mutants have only a slightly more severe phenotype than vt2 single mutants. Both spi1 and vt2 single mutants exhibit a reduction in free auxin levels, but the spi1/vt2 double mutants do not have a further reduction compared with vt2 single mutants | Zea mays |
metabolism | vt2 converts Trp to indole-3-pyruvic acid in one of four hypothesized Trp-dependent auxin biosynthesis pathways. Both spi1 and vt2 function in auxin biosynthesis in maize, possibly in the same pathway rather than independently | Zea mays |
physiological function | vt2 functions in axillary meristem formation during inflorescence development, but vt2 does not function in axillary meristem formation during vegetative development | Zea mays |
