Barren inflorescence1 functions in organogenesis during vegetative and inflorescence development in maize.
Maize (Zea mays) has a highly branched inflorescence due to the production of different types of axillary meristems. Characterization of the barren inflorescence class of mutants has led to the discovery of genes required for axillary meristem initiation in the inflorescence. Previous studies showed that barren inflorescence2 (bif2) encodes a serine/threonine protein kinase that regulates auxin...
متن کاملAuxin signaling modules regulate maize inflorescence architecture.
In plants, small groups of pluripotent stem cells called axillary meristems are required for the formation of the branches and flowers that eventually establish shoot architecture and drive reproductive success. To ensure the proper formation of new axillary meristems, the specification of boundary regions is required for coordinating their development. We have identified two maize genes, BARRE...
متن کاملsparse inflorescence1 encodes a monocot-specific YUCCA-like gene required for vegetative and reproductive development in maize.
The plant growth hormone auxin plays a critical role in the initiation of lateral organs and meristems. Here, we identify and characterize a mutant, sparse inflorescence1 (spi1), which has defects in the initiation of axillary meristems and lateral organs during vegetative and inflorescence development in maize. Positional cloning shows that spi1 encodes a flavin monooxygenase similar to the YU...

We consider the generation of a non-perturbative superpotential in F-theory compactifications with flux. For models with a single volume modulus, we show that the volume modulus is never stabilized by either abelian instantons or gaugino condensation. We then comment on how our analysis extends to a larger class of compactifications. From our results, it appears that among large volume string c...
متن کاملPhylogenomic analyses of the BARREN STALK1/LAX PANICLE1 (BA1/LAX1) genes and evidence for their roles during axillary meristem development.
The diversity of plant architectural form is largely determined by the extent and duration of axillary meristem (AM) derived lateral growth. The orthologous basic helix-loop-helix (bHLH) proteins maize BARREN STALK1 (BA1) and rice LAX PANICLE1 (LAX1) are essential for the formation of AMs during vegetative development and all lateral structures during inflorescence development, but whether BA1/...
