A revision of the Solanum elaeagnifolium clade (Elaeagnifolium clade; subgenus Leptostemonum, Solanaceae)
The Solanum elaeagnifolium clade (Elaeagnifolium clade) contains five species of small, often rhizomatous, shrubs from deserts and dry forests in North and South America. Members of the clade were previously classified in sections Leprophora, Nycterium and Lathyrocarpum, and were not thought to be closely related. The group is sister to the species-rich monophyletic Old World clade of spiny sol...
متن کاملFitness costs and benefits of novel herbicide tolerance in a noxious weed.
Glyphosate, the active ingredient in the herbicide RoundUp, has increased dramatically in use over the past decade and constitutes a potent anthropogenic source of selection. In the southeastern United States, weedy morning glories have begun to develop tolerance to glyphosate, representing a unique opportunity to examine the evolutionary genetics of a novel trait. We found genetic variation fo...
متن کاملSelective adaptation to noxious foods
feeding by herbivorous insects. Some of these noxious compounds are both unpalatable and toxic, while others are merely unpalatable or toxic (Bernays and Chapman, 1987; Chapman and Sword, 1994; Glendinning, 1996; Harley and Thorsteinson, 1967). Because many plants concentrate noxious compounds in their most nutritious tissues (McKey, 1979), herbivores would benefit from an ability to adapt to f...
متن کاملSpecialization and local adaptation of a fungal parasite on two host plant species as revealed by two fitness traits.
We investigate the geographic pattern of adaptation of a fungal parasite, Colletotrichum lindemuthianum, on two host species, Phaseolus vulgaris and P. coccineus for two parasite fitness traits: infectivity (ability to attack a host individual) and aggressivity (degree of sporulation and leaf surface damage). Using a cross-inoculation experiment, we show specialization of the fungus on its host...
متن کاملVirus infection of a weed increases vector attraction to and vector fitness on the weed
Weeds are important in the ecology of field crops, and when crops are harvested, weeds often become the main hosts for plant viruses and their insect vectors. Few studies, however, have examined the relationships between plant viruses, vectors, and weeds. Here, we investigated how infection of the weed Datura stramonium L. by tomato yellow leaf curl virus (TYLCV) affects the host preference and...
