Inheritance of Photoperiodic Response and Tillering I N Maize - Teosinte
نویسنده
چکیده
HE importance of day length as a determining factor in the time of T floral initiation in plants was first reported by GARNER and ALLARD (1920). Since then numerous investigations have been conducted on this phenomenon, and many plants have been classified into short-day, long-day and day-neutral types on the basis of their response to photoperiod. All known varieties of teosinte belong to the short-day group of plants, while North American maize varieties are little influenced by photoperiod, and may be classified as day-neutral types. The fact that fertile hybrids may be readily produced between maize and teosinte affords an excellent opportunity for a study of the inheritance of this short-day character in hybrids between the two species.

Natural variation in teosinte at the domestication locus teosinte branched1 (tb1)
The teosinte branched1(tb1) gene is a major QTL controlling branching differences between maize and its wild progenitor, teosinte. The insertion of a transposable element (Hopscotch) upstream of tb1 is known to enhance the gene's expression, causing reduced tillering in maize. Observations of the maize tb1 allele in teosinte and estimates of an insertion age of the Hopscotch that predates domes...

متن کاملGenetic and morphological analysis of a maize-teosinte F2 population: implications for the origin of maize.
Genes controlling the dramatic morphological differences between maize and its presumed progenitor (teosinte) were investigated in a maize-teosinte F2 population through the use of molecular markers. Results indicate that the key traits differentiating maize and teosinte are each under multigenic control, although for some traits, such as the number of ranks of cupules, the data are consistent ...
متن کاملThe genetics of maize evolution.
Maize and its closest wild relatives, the teosintes, differ strikingly in the morphology of their female inflorescences or ears. Despite their divergent morphologies, several studies indicate that some varieties of teosinte are cytologically indistinguishable from maize and capable of forming fully fertile hybrids with maize. Molecular analyses identified one form of teosinte (Zea mays ssp. par...
متن کاملInheritance of the morphological differences between maize and teosinte: comparison of results for two F2 populations.
Molecular marker loci (MMLs) were employed to map quantitative trait loci (QTLs) in an F2 population derived from a cross of maize (Zea mays ssp. mays) and its probable progenitor, teosinte (Z. mays ssp. parviglumis). A total of 50 significant associations (putative QTLs) between the MMLs and nine key traits that distinguish maize and teosinte were identified. Results from this analysis are com...
