The Evolution of Epitype [PDF]

Plant Cell, 2010
The epitype of a single gene or entire genome is determined by cis-linked differences in chromatin structure. I explore the hypothesis that "epitype and associated phenotypes evolve by gene duplication, divergence, and subfunctionalization" parallel to models for the evolution of genotype.

Epitype-inducing temperatures drive DNA methylation changes during somatic embryogenesis in the long-lived gymnosperm Norway spruce

Frontiers in Plant Science, 2023
An epigenetic memory of the temperature sum experienced during embryogenesis is part of the climatic adaptation strategy of the long-lived gymnosperm Norway spruce.

Temperature-induced variation in the transcriptome of maritime pine (Pinus pinaster Ait.) embryogenic masses modulates the phenotype of the derived plants [PDF]

BMC Genomics
A number of studies show that combining somatic embryogenesis with environmental stimuli can induce plant defenses against abiotic stresses, offering a complementary strategy in tree breeding programs.

Epitypification of Merismopedia tranquilla (Cyanobacteria) prompts phylogenetic reassessment of the genus and the description of two morphologically similar genera. [PDF]

J Phycol
Abstract The genus Merismopedia is morphologically characterized by its distinctive colony arrangement yet exhibits considerable variability among species. Recent studies suggested that Merismopedia is polyphyletic, and its most likely true lineage was provisionally placed within the Microcystaceae. However, the available molecular data for most of the

DNA Methylation Epitypes of Burkitt Lymphoma with Distinct Molecular and Clinical Features. [PDF]

Blood Cancer Discov
Abstract The genetic subtypes of Burkitt lymphoma have been defined, but the role of epigenetics remains to be comprehensively characterized. We searched genomic DNA from 218 patients across four continents for recurrent DNA methylation patterns and their associations with clinical and ...

Solving the Enigma of the Identity of Laccaria laccata [PDF]

Journal of Fungi
The taxonomy of Laccaria laccata, the type species of the genus Laccaria, has long been ambiguous due to the absence of a reference sequence and the reliance on early, morphology-based descriptions.

Challenges in Typification Within Taxonomically Complex Groups: The Case of the Linnaean Name Centaurea phrygia (Asteraceae) [PDF]

Plants
The Linnaean names have undergone significant changes over time, mainly in taxonomically complex aggregates where hybridisation or genetic introgression are frequent.

Translating tumor epigenetic subtyping into methylome network-based prognostic models in early-stage NSCLC: results from the prospective MOBIT study [PDF]

Journal of Translational Medicine
Background DNA methylation (DNAm) is a key epigenetic feature contributing to tumorigenesis with coordinated methylation changes across the genome potentially reflecting tumor biology and disease aggressiveness.

Genome methylation patterns in male breast cancer – Identification of an epitype with hypermethylation of polycomb target genes [PDF]

Molecular Oncology, 2015
Male breast cancer (MBC) is a rare disease that shares both similarities and differences with female breast cancer (FBC). The aim of this study was to assess genome‐wide DNA methylation profiles in MBC and compare them with the previously identified transcriptional subgroups of MBC, luminal M1 and M2, as well as the intrinsic subtypes of FBC.
