Abstract
The ecological role of genome size in plant biology, biogeography, and morphology has garnered increasing attention as the methods and technology associated with measuring cytological characteristics have become more reliable and accessible. However, how plant genome size influences plant invasions and at what stage in the invasion this influence occurs have been little explored. Several large-scale analyses of published data have yielded valuable interspecific comparisons, but experimental studies that manipulate environmental factors are needed, particularly below the species level, to fully understand the role that genome size plays in plant invasion. In this review, we summarize the available knowledge, discuss the integration of genome size data into invasion research, and suggest how it can be applied to detect and manage invasive species. We also explore how global climate change could exert selective pressures on plant populations with varying genome sizes, thereby increasing the distribution range and invasiveness of some populations while decreasing others. Finally, we outline avenues for future research, including considerations of large-scale studies of intraspecific variation in genome size of invasive populations, testing the interaction of genome size with other factors in macroecological analyses of invasions, as well as the role this trait may play in plant-enemy interactions.

Abstract
The accumulation of over 30 years of basic research on the biology, genetic variation, and evolution of the wild perennial relatives of soybean (Glycine max) provides a foundation to improve cultivated soybean. The cultivated soybean and its wild progenitor, G. soja, have a center of origin in eastern Asia and are the only two species in the annual subgenus Soja. Systematic and evolutionary studies of the ca. 30 perennial species of subgenus Glycine, native to Australia, have benefited from the availability of the G. max genomic sequence. The perennial species harbor many traits of interest to soybean breeders, among them resistance to major soybean pathogens such as cyst nematode and leaf rust. New species in the Australian subgenus continue to be described, due to the collection of new material and to insights gleaned through systematic studies of accessions in germplasm collections. Ongoing studies in perennial species focus on genomic regions that contain genes for key traits relevant to soybean breeding. These comparisons also include the homoeologous regions that are the result of polyploidy in the common ancestor of all Glycine species. Subgenus Glycine includes a complex of recently formed allopolyploids that are the focus of studies aimed at elucidating genomic, transcriptomic, physiological, taxonomic, morphological, developmental, and ecological processes related to polyploid evolution. Here we review what has been learned over the past 30 years and outline ongoing work on photosynthesis, nitrogen fixation, and floral biology, much of it drawing on new technologies and resources.

Mol Ecol 2014; 23:4168-83.

Abstract
Compared with plants and animals, large-scale biogeographic patterns of microbes including fungi are poorly understood. By the use of a comparative phylogenetic approach and ancestral state reconstructions, we addressed the global biogeography, rate of evolution and evolutionary origin of the widely distributed ectomycorrhizal (EcM) /sebacina lineage that forms a large proportion of the Sebacinales order. We downloaded all publicly available internal transcribed spacer (ITS) sequences and metadata and supplemented sequence information from three genes to construct dated phylogenies and test biogeographic hypotheses. The /sebacina lineage evolved 45-57 Myr ago that groups it with relatively young EcM taxa in other studies. The most parsimonious origin for /sebacina is inferred to be North American temperate coniferous forests. Among biogeographic traits, region and biome exhibited stronger phylogenetic signal than host family. Consistent with the resource availability (environmental energy) hypothesis, the ITS region is evolving at a faster rate in tropical than nontropical regions. Most biogeographic regions exhibited substantial phylogenetic clustering suggesting a strong impact of dispersal limitation over a large geographic scale. In northern Holarctic regions, however, phylogenetic distances and phylogenetic grouping of isolates indicate multiple recent dispersal events.

Abstract
Because orchids are dependent on mycorrhizal fungi for germination and establishment of seedlings, differences in the mycorrhizal communities associating with orchids can be expected to mediate the abundance, spatial distribution and coexistence of terrestrial orchids in natural communities. We assessed the small-scale spatial distribution of seven orchid species co-occurring in 25 × 25 m plots in two Mediterranean grasslands. In order to characterize the mycorrhizal community associating with each orchid species, 454 pyrosequencing was used. The extent of spatial clustering was assessed using techniques of spatial point pattern analysis. The community of mycorrhizal fungi consisted mainly of members of the Tulasnellaceae, Thelephoraceae and Ceratobasidiaceae, although sporadically members of the Sebacinaceae, Russulaceae and Cortinariaceae were observed. Pronounced differences in mycorrhizal communities were observed between species, whereas strong clustering and significant segregation characterized the spatial distribution of orchid species. However, spatial segregation was not significantly related to phylogenetic dissimilarity of fungal communities. Our results indicate that co-occurring orchid species have distinctive mycorrhizal communities and show strong spatial segregation, suggesting that mycorrhizal fungi are important factors driving niche partitioning in terrestrial orchids and may therefore contribute to orchid coexistence.
