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.

Differential Expression of Maize and Teosinte microRNAs under Submergence, Drought, and Alternated Stress

Plants, 2020
Submergence and drought stresses are the main constraints to crop production worldwide. MicroRNAs (miRNAs) are known to play a major role in plant response to various stresses.

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.

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).

Maize × Teosinte Hybridization

1994
The greatest part of the genetic variability of maize has been caused or maintained by the introgression of wild germplasm, especially of the taxa closest to the cultivated species: the teosintes. There exists good documentation regarding the existence of F1 Hybrids and advanced generations, derived from the same, produced by natural Hybridizations ...

Phyllochron estimate for the teosinte crop

Sigmae, 2023
O objetivo deste trabalho foi estimar o filocrono para a cultura de teosinto em datas de semeadura. Foi conduzido um experimento em 12 datas de semeadura (08/10/2021 a 01/01/2022). As semeaduras foram realizadas em uma fileira de 5 m de comprimento, espaçadas em 0,80 m entre fileiras e 0,20 m entre plantas na fileira. Em cada data de semeadura marcaram-

Seed Dormancy in Mexican Teosinte

Crop Science, 2011
Seed dormancy in wild Zea species may affect fitness and relate to ecological adaptation. The primary objective of this study was to characterize the variation in seed germination of the wild species of the genus Zea that currently grow in México and to relate this variation to their ecological zones of adaptation.

From Teosinte to Maize: The Catastrophic Sexual Transmutation

Science, 1983
An alternative to the theory that the ear of maize ( Zea mays ssp. mays ) evolved from a slender female ear of a Mexican annual teosinte holds that it was derived from the central spike of a male teosinte inflorescence (tassel) which terminates the primary lateral ...

Teosinte Branched 1 modulates tillering in rice plants

Plant Cell Reports, 2011
Tillering is an important trait of cereal crops that optimizes plant architecture for maximum yield. Teosinte Branched 1 (TB1) is a negative regulator of lateral branching and an inducer of female inflorescence formation in Zea mays (maize). Recent studies indicate that TB1 homologs in Oryza sativa (rice), Sorghum bicolor and Arabidopsis
