Chloroplast DNA variation confirms a single origin of domesticated sunflower (Helianthus annuus L.).
Although sunflower was long thought to be the product of a single domestication in what is now the east-central United States, recent archaeological and genetic evidence have suggested the possibility of an independent origin of domestication, perhaps in Mexico. We therefore used hypervariable chloroplast simple-sequence repeat markers to search for evidence of a possible Mexican origin of dome...
متن کاملGenetic Architecture of Capitate Glandular Trichome Density in Florets of Domesticated Sunflower (Helianthus annuus L.)
Capitate glandular trichomes (CGT), one type of glandular trichomes, are most common in Asteraceae species. CGT can produce various secondary metabolites such as sesquiterpene lactones (STLs) and provide durable resistance to insect pests. In sunflower, CGT-based host resistance is effective to combat the specialist pest, sunflower moth. However, the genetic basis of CGT density is not well und...
متن کاملA lack of linguistic evidence for domesticated sunflower in pre-Columbian Mesoamerica.
Lentz et al. (1) cite linguistic evidence supporting their hypothesis that Helianthus annuus was domesticated in Mesoamerica in pre-Columbian times. This consists, in part, of a list of names for sunflower collected from speakers of 14 contemporary native languages. They conclude that the fact that terms for sunflower in 11 of these languages do not phonologically resemble Spanish words for sun...
متن کاملThe Iconography of Vermin
aughty, sharp-tongued, self-assured, unbearably self-sufficient, stingy, and violent beyond measure , " is how Georges de La Tour was described by his contemporaries. Municipal records confirm that he refused to pay his share to feed the hungry during times of famine. He assaulted an officer, beat a peasant, and made himself obnoxious to everyone by " sending his dogs after hare into the standi...
متن کاملWinnowing the archaeological evidence for domesticated sunflower in pre-Columbian Mesoamerica.
Lentz et al. (1) propose that, along with being domesticated in eastern North America (ENA) by 2800 B.C. (2, 3), the sunflower was independently domesticated and widely cultivated in pre-Columbian Mesoamerica. Archaeological evidence presented, however, falls far short of an adequate supporting argument for their claim. Pre-Columbian contexts in ENA have yielded 3,000 domesticated sunflower ach...
