Gene Flow Among Different Teosinte Taxa and Into the Domesticated Maize Gene Pool

open access: yesGenetic Resources and Crop Evolution, 2011
International audienceMaize (Zea mays L. ssp. mays) was domesticated from one wild species ancestor, the Balsas teosinte (Zea mays ssp. parviglumis) about 9000 years ago.

Two teosintes made modern maize

Science, 2023
The origins of maize were the topic of vigorous debate for nearly a century, but neither the current genetic model nor earlier archaeological models account for the totality of available data, and recent work has highlighted the potential contribution of a wild relative, Zea mays ssp.

Teosinte crossing barrier1, a locus governing hybridization of teosinte with maize

Theoretical and Applied Genetics, 2001
A teosinte gene or gene cluster, Teosinte crossing barrier1 (Tcb1), that restricts crossability with maize mapped 6 centiMorgans distal to sugary-1 on chromosome 4. Tcb1 is loosely linked with the gametophyte-1 locus whose Ga1-s allele, present in many popcorns, confers nonreceptivity to the pollen of other maize varieties (ga1).

Teosinte Cytoplasmic Genomes: II. Performance of Maize Hybrids with Teosinte Cytoplasms

Crop Science, 1996
Alien cytoplasm substitution effects on quantitative agronomic characters in maize breeding germplasm have been studied many times, but few cytoplasmic effects have been found. This research was conducted to evaluate the importance of nuclear sources of variation often confounded with cytoplasmic effects, and to study effects of substituting teosinte ...

Teosinte Cytoplasmic Genomes: I. Performance of Maize Inbreds with Teosinte Cytoplasms

Crop Science, 1996
Cytoplasmic variation in maize (Zea mays L.) is known to influence qualitative phenotypes such as male sterility and teosinte‐cytoplasm‐associated miniature. Cytoplasmic influences on quantitative characters such as grain yield have been difficult to document.
