Natural variation in teosinte at the domestication locusteosinte branched1(tb1) [PDF]
PeerJ, 2014 AbstractPremise of the studyTheteosinte 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 oftb1is known to enhance the gene’s expression, causing reduced tillering in maize.

Ecogeography of teosinte [PDF]
PLOS ONE, 2018 Adaptation of crops to climate change has motivated an increasing interest in the potential value of novel traits from wild species; maize wild relatives, the teosintes, harbor traits that may be useful to maize breeding. To study the ecogeographic distribution of teosinte we constructed a robust database of 2363 teosinte occurrences from published ...

Teosinte Inflorescence Phytolith Assemblages Mirror Zea Taxonomy [PDF]
PLoS ONE, 2011 Molecular DNA analyses of the New World grass (Poaceae) genus Zea, comprising five species, has resolved taxonomic issues including the most likely teosinte progenitor (Zea mays ssp. parviglumis) of maize (Zea mays ssp. mays). However, archaeologically, little is known about the use of teosinte by humans both prior to and after the domestication of ...

PLoS Genetics, 2020 The genetics of domestication has been extensively studied ever since the rediscovery of Mendel's law of inheritance and much has been learned about the genetic control of trait differences between crops and their ancestors.

Mapping Prolificacy QTL in Maize and Teosinte [PDF]
Journal of Heredity, 2016 Teosinte, the ancestor of maize, possesses multiple ears at each node along its main stalk, whereas maize has only a single ear at each node. With its greater ear number, teosinte is referred to as being more prolific. The grassy tillers 1 (gt1) gene has been identified as a large-effect quantitative trait locus underlying this prolificacy difference ...

Genetic Diversity and Population Structure of Teosinte [PDF]
Genetics, 2005 Abstract The teosintes, the closest wild relatives of maize, are important resources for the study of maize genetics and evolution and for plant breeding. We genotyped 237 individual teosinte plants for 93 microsatellites. Phylogenetic relationships among species and subspecific taxa were largely consistent with prior analyses for ...

The role of cis regulatory evolution in maize domestication. [PDF]
PLoS Genetics, 2014 Gene expression differences between divergent lineages caused by modification of cis regulatory elements are thought to be important in evolution. We assayed genome-wide cis and trans regulatory differences between maize and its wild progenitor, teosinte,

Frontiers in Plant Science, 2021 Modern maize exhibits a significantly different phenotype than its wild progenitor teosinte despite many genetic similarities. Of the many subspecies of Zea mays identified as teosinte, Zea mays ssp.

EFSA Journal, 2022 Teosinte, wild maize relatives originating from Mexico and Central America, emerged as a noxious agricultural weed in France and Spain. In 2016, the European Food Safety Authority (EFSA) issued a technical report that assessed the available scientific ...
