mucoromycotina fine root endophyte fungi form nutritional mutualisms with Vascular Plants
Plant Physiology, 2019Co-Authors: Grace A Hoysted, Jeffrey G. Duckett, Alison S Jacob, Jill Kowal, Philipp Giesemann, Martin I Bidartondo, Gerhard Gebauer, William R RimingtonAbstract:Fungi and Plants have engaged in intimate symbioses that are globally widespread and have driven terrestrial biogeochemical processes since plant terrestrialization >500 million years ago. Recently, hitherto unknown nutritional mutualisms involving ancient lineages of fungi and nonVascular Plants have been discovered, although their extent and functional significance in Vascular Plants remain uncertain. Here, we provide evidence of carbon-for-nitrogen exchange between an early-diverging Vascular plant (Lycopodiella inundata) and Mucoromycotina (Endogonales) fine root endophyte fungi. Furthermore, we demonstrate that the same fungal symbionts colonize neighboring nonVascular and flowering Plants. These findings fundamentally change our understanding of the physiology, interrelationships, and ecology of underground plant–fungal symbioses in modern terrestrial ecosystems by revealing the nutritional role of Mucoromycotina fungal symbionts in Vascular Plants.

mucoromycotina fine root endophyte fungi form nutritional mutualisms with Vascular Plants
bioRxiv, 2019Co-Authors: Grace A Hoysted, Jeffrey G. Duckett, Alison S Jacob, Jill Kowal, Philipp Giesemann, Martin I Bidartondo, Gerhard Gebauer, William R RimingtonAbstract:Abstract Fungi and Plants have engaged in intimate symbioses that are globally widespread and have driven terrestrial biogeochemical processes since plant terrestrialisation >500 Mya. Recently, hitherto unknown nutritional mutualisms involving ancient lineages of fungi and non-Vascular Plants have been discovered. However, their extent and functional significance in Vascular Plants remains uncertain. Here, we provide first evidence of abundant carbon-for-nitrogen exchange between an early-diverging Vascular plant (Lycopodiaceae) and Mucoromycotina (Endogonales) fine root endophyte regardless of changes in atmospheric CO2 concentration. Furthermore, we provide evidence that the same fungi also colonize neighbouring non-Vascular and flowering Plants. These findings fundamentally change our understanding of the evolution, physiology, interrelationships and ecology of underground plant-fungal symbioses in terrestrial ecosystems by revealing an unprecedented nutritional role of Mucoromycotina fungal symbionts in Vascular Plants.

contrasting arbuscular mycorrhizal responses of Vascular and non Vascular Plants to a simulated palaeozoic co 2 decline
Nature Communications, 2012Co-Authors: Katie J Field, Martin I Bidartondo, Duncan D Cameron, Jonathan R Leake, S Tille, David J BeerlingAbstract:Vascular Plants with root systems evolved in the mid-Palaeozoic with symbiotic fungi. Field et al. show that in contrast to non-Vascular Plants lacking roots, the efficiency of plant–fungal symbiosis increased for Vascular Plants with root systems as carbon dioxide levels declined in the mid-Palaeozoic.

v phylomaker an r package that can generate very large phylogenies for Vascular Plants
Ecography, 2019Co-Authors: Yi Jin, Hong QianAbstract:We present V.PhyloMaker, a freely available package for R designed to generate phylogenies for Vascular Plants. The mega‐tree implemented in V.PhyloMaker (i.e. GBOTB.extended.tre), which was derived from two recently published mega‐trees and includes 74 533 species and all families of extant Vascular Plants, is the largest dated phylogeny for Vascular Plants. V.PhyloMaker can generate phylogenies for very large species lists (the largest species list that we tested included 314 686 species). V.PhyloMaker generates phylogenies at a fast speed, much faster than other phylogeny‐generating packages. Our tests of V.PhyloMaker show that generating a phylogeny for 60 000 species requires less than six hours. V.PhyloMaker includes an approach to attach genera or species to their close relatives in a phylogeny. We provide a simple example in this paper to show how to use V.PhyloMaker to generate phylogenies.

global concordance in diversity patterns of Vascular Plants and terrestrial vertebrates
Ecology Letters, 2008Co-Authors: Hong Qian, Robert E RicklefsAbstract:The factors that determine large-scale patterns of species richness are poorly understood. In particular, biologists have not determined the relative roles of taxon-specific characteristics that influence diversification and distribution, and region-specific features that promote and constrain diversity. We show that the numbers of species of Vascular Plants and of four terrestrial vertebrate taxa (mammals, birds, reptiles and amphibians) vary in parallel across 296 geographic areas covering most of the globe, even after accounting for sample area, climate, topographic heterogeneity and differences between continents. Thus, a common set of regional characteristics and processes appears to shape patterns of species richness in a diverse set of taxa, despite substantial differences in their biological traits.

a latitudinal gradient in large scale beta diversity for Vascular Plants in north america
Ecology Letters, 2007Co-Authors: Hong Qian, Robert E RicklefsAbstract:Species turnover, or beta diversity, has been predicted to decrease with increasing latitude, but few studies have tested this relationship. Here, we examined the beta diversity–latitude relationship for Vascular Plants at a continental scale, based on complete species lists of native Vascular Plants for entire states or provinces in North America (north of Mexico). We calculated beta diversity as the slope of the relationship between the natural logarithm of the Jaccard index (lnJ ) for families, genera or species, and both geographic distance and climate difference within five latitude zones. We found that beta diversity decreased from south to north; within latitude zones, it decreased from species to genera and families. Geographic and climatic distance explained about the same proportion of the variance in lnJ in zones south of c. 50°N. North of this latitude, nearly all the explained variance in lnJ was attributable to geographic distance. Therefore, decreasing beta diversity from south to north reflects decreasing climate differentiation within more northerly latitude zones, and primarily post-glacial dispersal limitation north of 50°N.

A COMPARISON OF GENERIC ENDEMISM OF Vascular Plants BETWEEN EAST ASIA AND NORTH AMERICA
International Journal of Plant Sciences, 2001Co-Authors: Hong QianAbstract:Biogeographic interpretations sometimes depend on endemism. The diversity of endemic genera of Vascular Plants in different phylogenetic groups was compared between East Asia and North America. North America has a significantly higher diversity of endemic genera of Vascular Plants than East Asia (987 vs. 754 genera). However, East Asia holds greater diversity of endemic genera than North America in pteridophytes, gymnosperms, and ranunculids, which are in general evolutionarily old taxa. The two areas do not significantly differ in the numbers of endemic genera in magnoliids and monocots. The overall diversity bias of endemic genera in favor of North America primarily results from caryophyllids, rosids, and asterids, which are relatively advanced lineages. As a result, numbers of endemic genera within phylogenetic groups do not vary in parallel between East Asia and North America. Compared with the world total flora with respect to proportions of numbers of taxa among phylogenetic groups, East Asia and No...
