“…This is unlikely based on the timing: given the changing distances between the islands involved, the proposed spread of Coriaria from the SH to the NH could have happened at the earliest near the end of the Oligocene 23 Mya. However, there is a Coriaria leaf fossil found in the Armissan bed in France which dates back to 23.2 to 33.9 Mya [ 7 , 48 ]. Furthermore, this scenario does not account for the presence of the continental lineage of Frankia cluster-2 in Japan and the Philippines.…”

“…As mentioned above, the common ancestor of all root nodule-forming plants including the actinorhizal Cucurbitales evolved in Gondwana. Based on a fossil-dated phylogeny [ 7 ], a northern hemisphere clade of Coriariaceae (NH) diverged from the southern hemisphere clade of Coriariaceae (SH) in the Paleocene (ca. 57 Mya).…”

“…Members of the genus Coriaria (Coriariaceae, Cucurbitales) have the broadest geographic range. They can be found in New Zealand, Papua New Guinea, the Philippines, Taiwan, Japan, China, Nepal, Pakistan, northern India, the Mediterranean, and the west coast of South America [ 7 , 21 ]. New Zealand is the center of diversity for Coriaria, with eight endemic species, while in any of the other regions only one or two different species can be found.…”

It is currently assumed that around 100 million years ago, the common ancestor to the Fabales, Fagales, Rosales and Cucurbitales in Gondwana, developed a root nodule symbiosis with a nitrogen-fixing bacterium. The symbiotic trait evolved first in Frankia cluster-2; thus, strains belonging to this cluster are the best extant representatives of this original symbiont. Most cluster-2 strains could not be cultured to date, except for Frankia coriariae, and therefore many aspects of the symbiosis are still elusive. Based on phylogenetics of cluster-2 metagenome-assembled genomes (MAGs), it has been shown that the genomes of strains originating in Eurasia are highly conserved. These MAGs are more closely related to Frankia cluster-2 in North America than to the single genome available thus far from the southern hemisphere, i.e., from Papua New Guinea.To unravel more biodiversity within Frankia cluster-2 and predict routes of dispersal from Gondwana, we sequenced and analysed the MAGs of Frankia cluster-2 from Coriaria japonica and Coriaria intermedia growing in Japan, Taiwan and the Philippines. Phylogenetic analyses indicate there is a clear split within Frankia cluster-2, separating a continental from an island lineage. Presumably, these lineages already diverged in Gondwana.Based on fossil data on the host plants, we propose that these two lineages dispersed via at least two routes. While the continental lineage reached Eurasia together with their host plants via the Indian subcontinent, the island lineage spread towards Japan with an unknown host plant.

1. The symbiosis between plants and nitrogen-fixing bacteria is widespread among legumes and actinorhizal plants within the nitrogen-fixing root nodule (NFN) clade. However, there are major differences, as well as similarities, in the symbioses between actinorhizal plants and Frankia and those of legumes and their associated rhizobia. 2. This review provides an overview of NFN symbioses. We outline the evolution and biogeography of actinorhizal plants and legumes and compare and contrast their microsymbionts and symbiotic processes. 3. Within the NFN clade, a far greater number of nodulated legumes exists, compared with actinorhizal plants, and legumes have a much wider biogeographical distribution. There are genetic and physiological differences between free-living diazotrophic Frankia and the phylogenetically diverse rhizobia, most strains of which are unable to fix N 2 ex planta. Actinorhizal nodules are modified lateral roots with a central vascular system, whereas legume nodules are stem-like organs with peripheral vascular systems. Most legumes contain their microsymbionts within symbiosomes, rather than the infection threads found in actinorhizal nodule cells. Legumes have greater control of their microsymbionts, and those within the Inverted Repeat Lacking Clade impose terminal differentiation on their bacteroids. Legumes also have effective processes for autoregulation of nodulation and downregulation of N 2 fixation in response to high levels of soil N. These features of the legume-rhizobia symbiosis have led to increased efficiencies in N 2 fixation. 4. Synthesis. We suggest that these characteristic features of the legume-rhizobia symbiosis, specifically legumes' greater flexibility in the choice of microsymbiont partner and the evolution of increased efficiencies in N 2 fixation, are factors that can explain why the majority of species within the Leguminosae have retained the ability to nodulate and how this has contributed to their evolutionary success.

“…A disjunct distribution pattern between the southern and the tropical Andes with a distribution gap at the arid zones of Atacama and Peruvian deserts has also been documented in several plant groups (reviewed in Lörch et al 2021). Some of them have been shown to have also split during the Miocene, coinciding with the formation of the Atacama and Peruvian deserts (Drew and Sytsma, 2013, Renner et al 2020, Lörch et al 2021. This arid barrier has also been suggested to limit north-south dispersal in wild South American camelids (Marín et al 2013, Casey et al 2018) and appears to split the distribution of Neotropical snakes on the western side of the Andes (Azevedo et al 2020b).…”

South American drylands roughly form two diagonals both termed in the biogeographical literature as the "South American dry diagonal" (SADD). However, they correspond to two different geographical areas. One comprises the Caatinga, Cerrado and Chaco domains, thus encompassing the areas between northeastern Brazil and northwestern Argentina. The other stretches from Patagonia in southern Argentina to the Pacific deserts of northern Chile and Peru, thus also including the Monte, Prepuna and dry Puna domains. I termed them the eastern and western SADDs, respectively (i.e., eSADD and wSADD). In this mini review I attempt to summarize the major climatic features of the two South American dry diagonals, their possible origins, biogeographical patterns within and around them and to explore possible interconnections. The eSADD is generally more humid than the wSADD and has more pronounced rainfall seasonality, with precipitation concentrated in summer, while the wSADD tends to be less seasonal due to year-round aridity, with little precipitation largely occurring in winter. The origin of both diagonals appears to go back to the middle Miocene, associated with global cooling. Biogeographical studies show that these diagonals are important in structuring South American distribution patterns south of the Equator, both acting as barriers for humid-adapted lineages and corridors for arid-adapted taxa. Remarkably, the two diagonals appear to have few plant and animal taxa in common, which may explain why biogeographers speaking about one diagonal seem to ignore the existence of the other. Highlights• Two South American regions have been referred to as the South American dry diagonals.• The first comprises the Caatinga, Cerrado and Chaco domains. The second encompasses Patagonia, Monte, Prepuna, dry Puna and Pacific Desert. • These two diagonals are key in structuring South American distribution patterns, acting both as dispersal barriers and corridors. • They appear to have little in common, both floristically and faunistically.
