Phylogeny and classification of Rosaceae
TLDR
Strong support for monophyly of groups corresponding closely to many previously recognized tribes and subfamilies is found, but no previous classification was entirely supported, and relationships among the strongly supported clades were weakly resolved and/or conflicted between some data sets.
Boreotropical migration explains hybridization between geographically distant lineages in the pantropical clade Sideroxyleae (Sapotaceae).
TLDR
It is concluded that Sideroxyleae, including the ancestral lineages of Nesoluma, were part of the boreotropical flora and entered the New World via the north Atlantic land bridge and it is suggested that the distribution of extant species resulted from the cooling climate at the end of the Eocene.
A Revised Time Tree of the Asterids: Establishing a Temporal Framework For Evolutionary Studies of the Coffee Family (Rubiaceae)
TLDR
The updated age estimates for major groups of Rubiaceae provide a significant step forward towards the long term goal of establishing a robust temporal framework for the divergence of this biologically diverse and fascinating group of plants.
Ancient allopolyploid speciation in Geinae (Rosaceae): evidence from nuclear granule-bound starch synthase (GBSSI) gene sequences.
TLDR
A nuclear low-copy gene phylogeny provides strong evidence for the hybrid origin of seven polyploid species in Geinae (Rosaceae) and indicates that the hexaploid lineage evolved through two consecutive allopolyploidization events.
Phylogenetic Relationships of Geum (Rosaceae) and Relatives Inferred from the nrITS and trnL-trnF Regions
TLDR
Morphological characters, notably fruit characters, mapped onto the combined tree show patterns of widespread parallel evolution and reversals—or possibly the effects of reticulations.
Deep divergences in the coffee family and the systematic position of Acranthera
TLDR
Nuclear ITS provided structured information at all phylogenetic levels, but the main gain from adding nrITS was the increased resolution and average support values also increased but were generally high also without nr ITS and the increase was not statistically significant.
Patterns of diversification amongst tropical regions compared: a case study in Sapotaceae
TLDR
The age and geographical origin of Manilkara are inferred to determine whether Gondwanan break-up, boreotropical migration or long distance dispersal have shaped its current disjunct distribution and whether the timing and tempo of speciation on each continent coincides with geoclimatic events.
Accounting for variation of substitution rates through time in Bayesian phylogeny reconstruction of Sapotoideae (Sapotaceae).
TLDR
Bayesian phylogenetic analysis of 5 kb of chloroplast DNA data from 68 Sapotaceae species showed that the ancestral type of flower in Sapotoideae may have been characterized by floral parts in single whorls of five, entire corolla lobes, and seeds with an adaxial hilum.
The influence of tectonics, sea-level changes and dispersal on migration and diversification of Isonandreae (Sapotaceae)
TLDR
The authors' results are consistent with migration from Africa into Sundania followed by numerous over-water dispersal events across Wallace's Line into Australasia and migration from Sundania to the Indian subcontinent and Pleistocene speciation indicates that sea-level changes during that epoch could have been responsible for some species diversification in Sundania.
