“…Morphological support for Chrysolepis and Lithocarpus as sister genera may be found in their welldefined cupule/fruit apomorphies. One possible synapomorphy for this relationship is the flower cupule (sensu Forman 1966) or simply that each pistillate flower in a dichasium is surrounded by cupular tissue, although the origin and interpretation of forms within this subclade requires additional developmental investigation .…”

An overview of recent achievements and development of genomic resources in the Fagaceae is provided, with major emphasis on the genera Castanea and Quercus. The Fagaceae is a large plant family comprising more than 900 species belonging to 8-10 genera. Using a wide range of molecular markers, population genetics and gene diversity surveys were the focus of many studies during the past 20 years. This work set the stage for investigations in genomics beginning in the early 1990s and facilitated the application of genetic and quantitative trait loci mapping approaches. Transferability of markers across species and comparative mapping have indicated tight macrosynteny between Quercus and Castanea. Omic technologies were more recently developed and the corresponding resources are accessible via electronic and physical repositories (expressed sequence tag sequences, single-nucleotide polymorphisms, candidate genes, cDNA clones, bacterial artificial chromosome (BAC) libraries) that have been installed in North America and Europe. BAC libraries and physical maps were also constructed in Castanea and Quercus and provide the necessary resources for full nuclear genome sequencing projects that are currently under way in Castanea mollissima (Chinese chestnut) and Quercus robur (pedunculate oak).

Within 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 outstanding trend with many correlated characteristics is exhibited by the adaptation to wind pollination in some groups of the Hamamelidales and especially in almost the whole of the Fagales. This seems to be one of the reasons for the dominant. position of the Fagales in the vegetation of temperate regions.

a b s t r a c tCuticle micromorphology of all eight species of Fagus and an outgroup were examined in the present study. The genus Trigonobalanus was selected as the outgroup. Thirteen characteristics of the inner surface and five of the outer surface of the cuticle were described. Some characteristics, such as the subsidiary cell shape, size of stomata, arrangement of subsidiary cell, shape of anticlinal and periclinal cell walls, texture of periclinal cell wall, development epicuticular wax, and presence of papillae, were considered important for infrageneric classification. The topology was obtained from the analysis using two major lineages: (1) Fagus engleriana þ Fagus japonica þ Fagus longipetiolata and (2) Fagus sylvatica þ Fagus crenata þ Fagus lucida þ Fagus hayatae þ Fagus grandifolia. The first clade supported a bootstrap value of 98% and the second clade a bootstrap value of 97%. Based on the cuticle morphology, our results support the previous study, by revealing F. engleriana, F. japonica, and F. longipetiolata with long peduncles in one group and the remaining extant species of short-to medium-length peduncles in another group. In addition, molecular phylogenetic study of Fagus based on ribosomal DNA ITS and chloroplast DNA sequences data supports this assemblage. This study shows that cuticle micromorphological characteristics provide useful and important information for analyzing the evolutionary aspects of Fagus.
