Definition of teosinte in English: teosintenoun ˌtiːəʊˈsɪnteɪˌtē-ōˈsintē mass nounA Mexican grass which is grown as fodder and is considered to be one of the parent plants of modern maize. 墨西哥类蜀黍,玉蜀黍墨西哥亚种 Zea mays subsp. mexicana, family Gramineae Example sentencesExamples - In fact, teosinte is so unlike modern corn, 19th century botanists did not even consider the two to be related.
- Consequently, they will help to increase our understanding of the gene-flow process in Mexico and Central America where teosinte and maize populations grow in geographic proximity and flower synchronously.
- Yet archaeological evidence indicates that people were cultivating teosinte, the ancestor of domesticated maize, more than 7,000 years ago.
- For decades plant biologists have been arguing about whether domestic maize is really a descendant of teosinte, a Mexican grass.
- Plants grown from teosinte seeds were pollinated with maize pollen.
- Comparison of these sequences with those from modern day maize and teosinte samples confirmed modern alleles were present in Mexican maize some 4400 years ago.
- We also examine genetic variation in teosinte for several quantitative traits that differentiate maize and teosinte.
- We observed a relatively low, although significant, level of differentiation between maize and teosinte.
- Even today, the original lineage of crop corn survives in a lanky grass called teosinte, which has tiny stubs of seeds that only a botanist could love.
- In corn, for example, just five regions explain most of the difference between modern crops and wild teosinte.
- Subspecies mexicana is the teosinte that grows most commonly in maize fields and has been observed to hybridize readily with maize.
- After retirement, he did extensive genetic experiments and became convinced that a rather small number of mutations could convert teosinte into a reasonable facsimile of maize.
OriginLate 19th century: from French téosinté, from Nahuatl teocintli, apparently from teo:tl 'god' + cintli 'dried ear of maize'.
