Subgenome evolution in allotetraploid plants [PDF]
The Plant Journal, 2021 SUMMARYPolyploidization is a well‐known speciation and adaptation mechanism. Traces of former polyploidization events were discovered within many genomes, and especially in plants. Allopolyploidization by interspecific hybridization between two species is common.

Frontiers in Genetics, 2020 We take advantage of synteny blocks, the analytical construct enabled at the evolutionary moment of speciation or polyploidization, to follow the independent loss of duplicate genes in two sister species or the loss through fractionation of syntenic ...

Welwitschia: Phylogeography of a living fossil, diversified within a desert refuge
Scientific Reports, 2021 Welwitschia mirabilis is one of the most extraordinary plant species on earth. With a fossil record of 112 My and phylogenetically isolated within the order Gnetales, the monotypic genus Welwitschia has survived only in the northern Namib Desert in ...

The Coevolution of Plants and Microbes Underpins Sustainable Agriculture
Microorganisms, 2021 Terrestrial plants evolution occurred in the presence of microbes, the phytomicrobiome. The rhizosphere microbial community is the most abundant and diverse subset of the phytomicrobiome and can include both beneficial and parasitic/pathogenic microbes ...

Evolutionary radiations in the species-rich mountain genus Saxifraga L.
BMC Evolutionary Biology, 2017 Background A large number of taxa have undergone evolutionary radiations in mountainous areas, rendering alpine systems particularly suitable to study the extrinsic and intrinsic factors that have shaped diversification patterns in plants.

The inevitability of C4 photosynthesis
eLife, 2014 Elements of C4 photosynthesis—a complex adaptation that increases photosynthetic efficiency—may have evolved first to correct an intercellular nitrogen imbalance, and only later evolved a central role in carbon fixation.

Phylogeny of Dorstenia (Moraceae) reveals the polyphyletic nature of its neotropical sections
Rodriguésia, 2021 Dorstenia, the second largest genus of Moraceae, comprises nine sections that are mainly found in Africa and America. Two of them are woody macrospermous, and the other seven are herbaceous microspermous.

Dynamical Patterning Modules, Biogeneric Materials, and the Evolution of Multicellular Plants
Frontiers in Plant Science, 2018 Comparative analyses of developmental processes across a broad spectrum of organisms are required to fully understand the mechanisms responsible for the major evolutionary transitions among eukaryotic photosynthetic lineages (defined here as the ...
