Molecular and Genome Evolution in the Malesian Slipper Orchids (Paphiopedilum section Barbata).
Paphiopedilum section Barbata (Cypripedioideae: Orchidaceae) is an evolutionarily young and charismatic group of terrestrial orchids native to the Himalayas, Indochina and Malesia. It contains several interesting species complexes, variable chromosome numbers (2n=28-42) and genome sizes (2C=55-70 pg) with hybrid speciation suspected on the basis of morphological data. In Chapter 1,...Yap, Jing Wei

A highly contiguous genome assembly reveals sources of genomic novelty in the symbiotic fungus Rhizophagus irregularis.
The root systems of most plant species are aided by the soil foraging capacities of symbiotic Arbuscular Mycorrhizal (AM) fungi of the Glomeromycotina subphylum. Despite recent advances in our knowledge of the ecology and molecular biology of this mutualistic symbiosis, our understanding of the AM fungi genome biology is just... -

How diverse is heterochromatin in the Caesalpinia group? Cytogenomic characterization of Erythrostemon hughesii Gagnon & G.P. Lewis (Leguminosae: Caesalpinioideae)
Main conclusion Cytogenomic characterization of Erythrostemon hughesii reveals a heterogeneity of repeats in its subtelomeric heterochromatin. Comparative analyses with other Caesalpinia group species reveal a significant reduction in the abundance of Ty3-gypsy/Chromovirus Tekay retrotransposons during its evolution. In numerically stable karyotypes, repetitive DNA variability is one of the main causes...Mata-Sucre, Yennifer ; Sader, Mariela ; Van-Lume, Brena ; Gagnon, Edeline ; Pedrosa-Harand, Andrea …
