REFMAKER: Make your own reference to target nuclear loci in low coverage genome skimming libraries. Phylogenomic application in Sapotaceae.

Genome skimming approach is widely used in plant systematics to infer phylogenies mostly from organelle genomes. However, organelles represent only 10 % of the produced libraries, and the low coverage associated with these libraries (<3X) prevents the capture of nuclear sequences, which are not always available in non-model organisms or limited to the ribosomal regions. We developed REFMAKER, a user-friendly pipeline, to create specific sets of nuclear loci that can be extracted directly from the genome skimming libraries.

Species Delimitation and Conservation in Taxonomically Challenging Lineages: The Case of Two Clades of (Sapotaceae) in Madagascar.

is the largest endemic genus of plants from Madagascar, with around 76% of its species threatened by deforestation and illegal logging. However, some species are not well circumscribed and many of them remain undescribed, impeding a confident evaluation of their conservation status. Here we focus on taxa delimitation and conservation of two species complexes within : the Arid and Western complexes, each containing undescribed morphologies as well as intermediate specimens alongside well-delimited taxa.

Phylogeographic reconstructions can be biased by ancestral shared alleles: The case of the polymorphic lichen Bryoria fuscescens in Europe and North Africa.

Large phylogeographic studies on lichens are scarce, and none involves a single species within which different lineages show fixed alternative dispersal strategies. We investigated Bryoria fuscescens (including B. capillaris) in Europe and western North Africa by phenotypically characterizing 1400 specimens from 64 populations and genotyping them with 14 microsatellites.

Evolutionary Trends in the Mitochondrial Genome of Archaeplastida: How Does the GC Bias Affect the Transition from Water to Land?

Among the most intriguing mysteries in the evolutionary biology of photosynthetic organisms are the genesis and consequences of the dramatic increase in the mitochondrial and nuclear genome sizes, together with the concomitant evolution of the three genetic compartments, particularly during the transition from water to land. To clarify the evolutionary trends in the mitochondrial genome of Archaeplastida, we analyzed the sequences from 37 complete genomes. Therefore, we utilized mitochondrial, plastidial and nuclear ribosomal DNA molecular markers on 100 species of Streptophyta for each subunit.

Evolution of complex symbiotic relationships in a morphologically derived family of lichen-forming fungi.

We studied the evolutionary history of the Parmeliaceae (Lecanoromycetes, Ascomycota), one of the largest families of lichen-forming fungi with complex and variable morphologies, also including several lichenicolous fungi. We assembled a six-locus data set including nuclear, mitochondrial and low-copy protein-coding genes from 293 operational taxonomic units (OTUs). The lichenicolous lifestyle originated independently three times in lichenized ancestors within Parmeliaceae, and a new generic name is introduced for one of these fungi.

Characterization of microsatellite loci in lichen-forming fungi of Bryoria section Implexae (Parmeliaceae).

Premise Of The Study: The locally rare, haploid, lichen-forming fungi Bryoria capillaris, B. fuscescens, and B. implexa are associated with boreal forests and belong to Bryoria sect.
