Phenylpropanoid patterns in fagales pollen and their phylogenetic relevance
Phytochemistry, 1988Abstract The occurrence of hydroxycinnamic acid-spermidine amides and quercetin 3- O -glucosylgalactoside in pollen of Fagales and some other taxa of the Hamamelididae ( sensu Takhtajan and Cronquist) has been investigated. The genera Alnus , Betula , Corylus , and Quercus show characteristic patterns of N 1 ,N 10 -di-( E )-feruloylspermidine ...

Spatial phylogenetics of Fagales: Investigating the history of temperate forests
2023AimQuantifying the phylogenetic diversity of temperate trees is essential for understanding what processes are implicated in shaping the modern distribution of temperate broadleaf forest and other major forest biomes. Here we focus on Fagales, an iconic member of forests worldwide, to uncover global diversity and endemism patterns and investigate ...

Fagalean phylogeny in a nutshell: Chronicling the diversification history of Fagales
2023AbstractReconstructing the biogeographical history and timing of the diversification of temperate forests is essential for understanding their history and resolving uncertainties about how flowering plants emerged from their deep tropical origins to dominate in today’s freezing terrestrial environments.

Evolutionary Trends in the Hamamelidales-Fagales-Group
1977Within the Hamamelidales-Fagales-complex putative evolutionary trends are outlined. Structure of inflorescences, flowers, pollen, fruits, and seeds, and peculiarities of the life history, particularly the general delay of ovule development and syngamy in relation to anthesis are demonstrated in the context of pollination and dispersal biology. The most

The evolution of fertilization modes independent of the micropyle in Fagales and `pseudoporogamy'
Plant Systematics and Evolution, 2006In contrast to a majority of angiosperms showing porogamous fertilization, several fagalean families such as Betulaceae and Casuarinaceae are known to show chalazogamy, where fertilization is effected by a pollen tube passing through the chalaza instead of the micropyle.
