  • progressively
  • Plants in the nightshade (Solanaceae) family ( 7 ), particularly tomato ( Solanum lycopersicum ), are models for sympodial growth, and inflorescence architectures range from a solitary flower, as in petunia ( 8 ), to progressively more complex structures in which the meristem proliferates into multiple branches with dozens of flowers, as in several wild species of tomato ( 9 ).

  • organism
  • The most undifferentiated cell is the zygote or fertilized egg, since the egg will produce all the cells of an organism. (blogspot.com)
  • mutants
  • Because meristem ontogenies between s mutants and normal plants are nearly identical, we proposed that s inflorescences might be highly branched due to a molecular delay in meristem maturation and termination that results in an extended period of indeterminacy, during which additional sympodial meristems, and therefore branches, develop. (pnas.org)
  • In these strong mutants, many ectopic stamens are formed in the region where the gynoecium is produced in the wild-type flower and they are arranged in a non-whorled, alternate pattern. (biologists.org)
  • organ
  • Cell-to-cell signaling networks maintain this population, but how are meristem and organ identities controlled? (plantcell.org)
  • signals
  • The brain produces electrical signals, which, together with chemical reactions, let the parts of the body communicate. (powershow.com)
  • seeds
  • The biological function of a flower is to mediate the union of male sperm with female ovum in order to produce seeds. (thefullwiki.org)
  • plants
  • The alternation between meristem termination and renewal in sympodial plants provides the foundation for a wide range of inflorescence types showing extensive variation in branch and flower number ( 5 , 6 ), but the basis for sympodial growth and branching diversity is poorly understood. (pnas.org)
  • A cross between two such homozygous plants produces a uniform population of hybrid plants that are heterozygous for many gene loci. (google.com)
  • tomatoes
  • 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 ).

  • The law suit ended with an agreement between the two companies that Calgene was allowed to make market range GM tomatoes while Zaneca would produce GM tomato processed goods. (prezi.com)
