  • Initiation
  • Scanning electron microscopy, histology and RNA in situ hybridization using knotted1 as a marker for meristematic tissue show that barren inflorescence2 mutants make fewer branches owing to a defect in branch meristem initiation. (usda.gov)
  • Furthermore, the defect in branch meristem formation provides insight into the role of knotted1 and barren inflorescence2 in axillary meristem initiation. (usda.gov)
  • primordia
  • Axillary meristems, which form in the axils of leaf primordia, give rise to branches and flowers and therefore play a critical role in plant architecture and reproduction. (usda.gov)
  • The construction of the double mutant between barren inflorescence2 and tasselsheath reveals that the function of barren inflorescence2 is specific to the formation of branch meristems rather than bract leaf primordia. (usda.gov)
  • mutant
  • Introgression of the barren inflorescence2 mutant into genetic backgrounds in which the phenotype was weaker illustrates additional roles of barren inflorescence2 in these axillary meristems. (usda.gov)
  • influence meristem
  • Some aspects of the fzt phenotype can be explained by reduced levels of known miRNAs, including miRNAs that influence meristem determinacy, phase change, and leaf polarity. (uncg.edu)
  • 1997
  • 1997 ). This means that, following a manipulation stimulus, seedlings are able to register and store "meristem-production" information but that they require a transient depletion of calcium to allow them to make use of the stored information-to recall it-for the actual induction of meristems.

  • developmental
  • iTRAQ-based quantitative proteomic analysis reveals the lateral meristem developmental mechanism for branched spike development in tetraploid wheat (Triticum turgidum L. (beds.ac.uk)
  • The genetic basis of RSs and FRSs has been analyzed, but little is known about the underlying developmental mechanisms of the lateral meristem. (beds.ac.uk)
  • morphology
  • Surprisingly, we find thousands of age-dependent expression changes, even when there is little change in meristem morphology. (pnas.org)
  • mutations
  • Carpenter, R., and Coen, E. S. (1990) Floral homeotic mutations produced by transposon-mutagenesis n Antirrhinum majus . (springer.com)
  • Most cultivated tomatoes produce inflorescences with a few flowers arranged in a zigzag branching pattern ( Fig. 1 A - E ), but we previously showed that variants with highly branched inflorescences bearing hundreds of flowers arose more than a century ago due to loss-of-function mutations in a homeobox transcription factor encoded by the COMPOUND INFLORESCENCE ( S ) gene ( Fig. 1 G ) ( 10 ).

  • Mutations of spike architecture in tetraploid wheat ( Triticum turgidum L., 2n = 28, AABB) can produce branched spikes or supernumerary spikelets. (beds.ac.uk)
