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

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.

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.

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

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.

Typification and new synonyms of tea (Camellia sinensis, Theaceae) and one of its infraspecific taxa [PDF]

PhytoKeys
Tea, Camellia sinensis, is a world-widely popular beverage source shrub. Its basionym, Thea sinensis, was lectotypified as a vague illustration, which cannot precisely exhibit the diagnostic character states of the species.

Lectotypification of Pterocarya serrata C.K.Schneider (Juglandaceae), the name of a forgotten species of wingnuts [PDF]

PhytoKeys
The Juglandaceae species Pterocarya serrata C.K.Schneid. was first described in 1912, but its assumed holotype, a flowering E. H. Wilson collection in the Vienna herbarium, was destroyed during World War II. Schneider described P.

How do I publish the name of a new species of algae? A basic guide. [PDF]

J Phycol
Abstract A basic guide to the requirements of the International Code of Nomenclature for algae, fungi, and plants for the publication of a valid name of new species (and infraspecific taxa) of living algae is provided. It is intended to aid phycologists so that an accurate inventory of the world's algal diversity is achieved.

Reinstatement of Memecylon elegantulum (Melastomataceae) and recircumscription of Memecylon rostratum, two species endemic to Sri Lanka [PDF]

PhytoKeys
Memecylon elegantulum Thwaites, a heterotypic synonym of M. rostratum Thwaites, is re-instated based on recent collections and field observations.
