Flowering and determinacy in maize.
All plant organs are produced by meristems, groups of stem cells located in the tips of roots and shoots. Indeterminate meristems make an indefinite number of organs, whereas determinate meristems are consumed after making a specific number of organs. Maize is an ideal system to study the genetic control of meristem fate because of the contribution from determinate and indeterminate meristems t...
متن کاملFlowering and determinacy in Arabidopsis.
Meristems provide new cells to produce organs throughout the life of a plant, and their continuous activity depends on regulatory genes that balance the proliferation of meristem cells with their recruitment to organogenesis. During flower development, this balance is shifted towards organogenesis, causing the meristem to terminate after producing a genetically determined number of organs. In A...

2000, Simpson et al., 2001). A more comprehensive model proposes fl owering as a part of shoot maturation process (Schultz and Haughn, 1991). Current research aims at clarifying the relationship among the various genes and group them into different, yet overlapping, signaling pathways, and deciphering the molecular mechanism of how the repressors work, e.g., what genes they repress, and how the...
متن کاملDeterminacy and determinacy analysis
One attractive, unique feature of logic programming languages is their ability to succinctly and declaratively express search. The alternatives of a search can be speci ed by a set of clauses de ning the same predicate. By backtracking, considering in turn each of these clauses, the di erent alternatives are explored until a solution (if it exists) is found. However, though backtracking is esse...
متن کاملThe genetic architecture of maize flowering time.
Flowering time is a complex trait that controls adaptation of plants to their local environment in the outcrossing species Zea mays (maize). We dissected variation for flowering time with a set of 5000 recombinant inbred lines (maize Nested Association Mapping population, NAM). Nearly a million plants were assayed in eight environments but showed no evidence for any single large-effect quantita...
