Homoploid hybrid origin of Yucca gloriosa: intersectional hybrid speciation in Yucca (Agavoideae, Asparagaceae)
There is a growing appreciation for the importance of hybrid speciation in angiosperm evolution. Here, we show that Yucca gloriosa (Asparagaceae: Agavoideae) is the product of intersectional hybridization between Y. aloifolia and Y. filamentosa. These species, all named by Carl Linnaeus, exist in sympatry along the southeastern Atlantic coast of the United States. Yucca gloriosa was found to sh...
متن کاملMicrosatellite primers in Agave utahensis (Asparagaceae), a keystone species in the Mojave Desert and Colorado Plateau1
UNLABELLED PREMISE OF THE STUDY Utah agave (Agave utahensis) and its putative subspecies, A. utahensis subsp. kaibabensis and A. utahensis subsp. utahensis, are keystone species of the Mojave Desert and Colorado Plateau in the southwestern United States. Here we developed microsatellite markers to study population structure and genetic diversity of the two subspecies of A. utahensis. • MET...
متن کاملA new species of Dasineura Rondani (Diptera: Cecidomyiidae) in flower galls of Camassia (Asparagaceae: Agavoideae) in the Pacific Northwest, USA.
A new species, Dasineura camassiae Gagné (Diptera: Cecidomyiidae), is described, illustrated and compared to some of its congeners from related hosts and western North America. The new species causes flower galls on Camassia (Agavoideae; Asparagaceae) in the Pacific Northwest. Its current known distribution is Oregon and Washington, USA. Larvae develop in spring in flowers of Camassia spp., cau...
متن کاملEmbryo sac formation and early embryo development in Agave tequilana (Asparagaceae)
Agave tequilana is an angiosperm species that belongs to the family Asparagaceae (formerly Agavaceae). Even though there is information regarding to some aspects related to the megagametogenesis of A. tequilana, this is the first report describing the complete process of megasporogenesis, megagametogenesis, the early embryo and endosperm development process in detail. The objective of this work...
متن کاملPhysical mapping of 5S and 18S ribosomal DNA in three species of Agave (Asparagales, Asparagaceae)
Agave Linnaeus, 1753 is endemic of America and is considered one of the most important crops in Mexico due to its key role in the country's economy. Cytogenetic analysis was carried out in Agave tequilana Weber, 1902 'Azul', Agave cupreata Trelease et Berger, 1915 and Agave angustifolia Haworth, 1812. The analysis showed that in all species the diploid chromosome number was 2n = 60, with bimoda...
