- Phytolaccaceae infructescence from Cerro del Pueblo Formation, Upper Cretaceous (late Campanian), Coahuila, Mexico
[作者:Cevallos-Ferriz, SRS; Estrada-Ruiz, E; Perez-Hernandez, BR,期刊:American Journal of Botany, 页码:77-83 , 文章类型: Article,,卷期:2008年95-1]
- The Upper Cretaceous (late Campanian) Cerro del Pueblo Formation, Coahuila, Mexico, contains a diverse group of angiosperms represented mainly by their reproductive structures. Among these, a new permineralized infructes...
- Resistance and tolerance to herbivory changes with inbreeding and ontogeny in a wild gourd (Cucurbitaceae)
[作者:Du, DL; Winsor, JA; Smith, M; Denicco, A; Stephenson, AG,期刊:American Journal of Botany, 页码:84-92 , 文章类型: Article,,卷期:2008年95-1]
- Herbivory is a ubiquitous component of terrestrial communities that reduces plant growth and reproduction. Consequently, a goal of evolutionary ecology is to identify the causes and consequences of variation in herbivory...
- Organization of the root apical meristem in angiosperms
[作者:Heimsch, C; Seago, JL,期刊:American Journal of Botany, 页码:1-21 , 文章类型: Review,,卷期:2008年95-1]
- Although flowers, leaves, and stems of the angiosperms have understandably received more attention than roots, the growing root tips, or root apical meristems (RAMs), are organs that could provide insight into angiosperm...
- Effects of cell number and cell size on petiole length variation in a stoloniferous herb
[作者:Weijschede, J; Antonise, K; de Caluwe, H; de Kroon, H; Huber, H,期刊:American Journal of Botany, 页码:41-49 , 文章类型: Article,,卷期:2008年95-1]
- In stoloniferous species, the length of petioles is of pivotal importance because it determines the position of leaf blades within the canopy. From a mechanistic perspective, two developmental processes, cell division an...
- Origins, distribution, and local co-occurrence of polyploid cytotypes in Solidago altissima (Asteraceae)
[作者:Halverson, K; Heard, SB; Nason, JD; Stireman, JO,期刊:American Journal of Botany, 页码:50-58 , 文章类型: Article,,卷期:2008年95-1]
- There is growing realization that intraspecific polyploidy in plants has important implications for the evolution of plant diversity and for plant and plant-herbivore community dynamics. Nonetheless, the rate at which po...
