DNA methylation and histone post-translational modifications have been described as epigenetic regulation mechanisms involved in developmental transitions plants, including seasonal changes fruit trees. In species like almond (Prunus dulcis (Mill.) D.A: Webb), prolonged exposure to cold temperatures is required for dormancy release flowering.

This study focused on three species that occur disjunctly between western North America and the Mediterranean region of southern Europe, northern Africa, Asia, forming so‐called Madrean‐Tethyan distribution pattern. Quantitative morphological characters were measured in New Old World plants to find any subtle phenotypic differentiation disjunct populations. Sequences from nuclear ribosomal internal transcribed spacer obtained same populations assess at molecular level compare diversity with...

Abstract Bayesian analysis of an alignment 83 nrITS sequences belonging to 66 taxa Pottiaceae revealed representatives subfamily Trichostomoideae in a well supported monophyletic lineage. Two robust clades within include species Tortella and Weissia , respectively. Eucladium verticillatum is part Trichostomoideae, Anoectangium Gymnostomum Hymenostylium Tuerckheimia form basal clade. Affinities Hyophila Leptobarbula are unclear. Within Pleurochaete squarrosa resolved while Trichostomum...

This review summarizes current state addresses most urgent remaining problems in unravelling systematic relationships mosses. main results early molecular phylogenetic reconstructions based on few chloroplast markers compared with recent approaches from different genomes as well a new phylogeny novel combination non-coding plastid (rps4-trnF region atpB-rbcL spacer)....

Phylogenetic analyses of infraspecific molecular data in relation to geographic and ecological information has come be known as phylogeography. Bryophytes offer fertile material for such analyses, which can help clarify long standing biogeographic questions that were intractable before became available. In particular, distinguish between dispersal fragmentation explanations disjunct distributions characterize many bryophytes at the specific well higher levels. Phylodemography is application...

Abstract Large genera, that were defined using a restricted suite of morphological characters, are particularly prone to be polyphyletic. We analysed representative selection species traditionally assigned the genus Barbula, believed represent largest moss family Pottiaceae, but which recently was suggested Special attention paid Barbula sect. Hydrogonium and Convolutae, in phylogenetic relationships likely incongruent with traits, could have evolved adaptation hydric otherwise extreme...

While revising samples of Dialytrichia saxicola in LISU preparation for IUCN Threatened Species Europe assessments, (Sérgio & Porley 2019) we found a collection from Italy that matched the typical expression this species.The population trend species was suspected to be increasing, favoured perhaps by eutrophication, and it predicted new areas occurrence may 2019).It therefore assessed as Least Concern, considered native Belgium, mainland France, Germany, Netherlands, Portugal, Madeira, Spain...

Abstract In higher plants the phytohormone ABA is involved in processes that are connected to water deficit, like stomatal closure or desiccation tolerance. bryophytes, also containing their tissues, physiological functions remained uncertain for a long time. Quite recently, several papers have shown different effects of exogenously applied ABA: Anthoceros , drought hardening Funaria and production landform Riccia . all these cases relevant conditions (water deficit) enhance endogenous level...

AbstractAbstractPCR (polymerase chain reaction) has become one of the most important techniques used in molecular systematics. Generally, methods applied to isolate DNA for PCR amplification depend on multiple steps and clean final product. This involves considerable effort time when many samples have be processed poisonous organic solvents are often needed (phenol, chloroform etc.). In this contribution, two very rapid simple intended use higher plants shown useful bryophyte biology: direct...

Species boundaries are sometimes difficult to assess, especially when molecular data do not neatly match morphologically defined units. This study investigates the moss genus Isothecium, with special emphasis on Macaronesian populations. Morphological studies combined analysis of three rapidly evolving markers: nuclear internal transcribed spacer and plastid trnG trnL-trnF. The results morphological suggest that Isothecium is represented by five species in Macaronesia, including a new...

Abstract The common cord moss Funaria hygrometrica has a worldwide distribution and thrives in wide variety of environments. Here, we studied the genetic diversity F. along an abiotic gradient Mediterranean high mountain Sierra Nevada (Spain) using genome scan method. Eighty‐four samples from 17 locations 24 to 2700 m were fingerprinted based on their amplified fragment length polymorphism ( AFLP ) banding pattern. Using PCA Bayesian inference found that was structured three or four...

Abstract In the Erzgebirge, which is part of Saxo-Thuringian Mid-European Variscides, an 40 Ar/ 39 Ar study was performed on white mica and hornblende separates from 68 metamorphic rocks varying lithologies. Two groups late Early Carboniferous cooling ages 340 ± 2 Ma 329.7 1.5 are distinguished by evaluating spectra shapes. A third group yielded intermediate argon ages, presumably related either to thermal rejuvenation or neoformation during a reheating process 330 ago. model that explains...

The recent assembly of the complete sequence plastid genome model taxon Physcomitrella patens (Funariaceae, Bryophyta) revealed that a 71-kb fragment, encompassing much large single copy region, is inverted. This inversion 57% largest rearrangement detected in genomes plants to date. Although initially considered diagnostic patens, was recently shown characterize two species from related genera within Funariaceae, but lacking another member Funariidae. phylogenetic significance has remained...

• Premise of the study: The Baas Becking tenet posits that ‘everything is everywhere, but environment selects’ to explain cosmopolitan distributions in highly vagile taxa. Bryophyte species show wider than vascular plants and include examples truly ranges, which have been interpreted as a result high dispersal capacities ecological plasticity. In current study, we documented patterns genetic structure diversity moss Bryum argenteum along an elevational gradient determine if homogenized by...
