“…Dumort. species [9,10], which were later confirmed by various markers based on direct DNA analyses [11][12][13]. Recently, an integrative approach based on morphology and molecular dataset enabled the split of the genus Pellia into Apopellia and Pellia sensu stricto [14].…”

Comparative Analysis of Apopellia endiviifolia Plastomes Reveals a Strikingly High Level of Differentiation between Its Terrestrial and Water Form

The simple thalloid liverwort Apopellia endiviifolia is a widespread Holarctic species belonging to the family Pelliaceae. European populations of this species comprise two distinct evolutionary lineages named “species A”, known also as water form, and typical, mainly terrestrial forms named “species B”. Newly sequenced, assembled and annotated chloroplast genomes of six European specimens belonging to the two cryptic lineages occupying different microhabitats, revealed the structure typical for liverworts and previously sequenced reference. The plastomes of A. endiviifolia are 120,537–120,947 bp long with a structure typical for most plants, including a pair of IR regions (each of 9092–9207 bp) separated by LSC (82,506–82,609 bp) and SSC (19,854–19,924 bp) regions and consist of 121 unique genes, including 81 protein-coding genes, 6 genes of unknown function (ycf genes), 4 ribosomal RNAs and 30 transfer RNAs. Comparative analysis of typical, terrestrial and water forms revealed 4971 molecular diagnostic characters (MDCs), which exceeds numbers found in many well recognized liverworts taxa. Moreover, beside the presence of evolutionary hotspots like ycf1 and ycf2 genes and several intergenic spacer like ndhB-psbM, rps4-ndhJ and ndhC-atpE, the molecular identification of Apopellia cryptic species was possible by almost 98% of 500 bp long frames simulating mini barcodes. The different ecological niches can be driven by different pressures of positive selection, which was detected in nine genes including ccsA, ndhD, ndhF, petA, psbB, psbC, rpoB, ycf1 and ycf2. Despite clearly genetic differences and ecological preferences, the current observation of morphological differentiation does not no allow to separate terrestrial and water forms into taxonomic species.

“…Genetically, i.e., based on isozyme patterns (e.g., peroxidases), there are two groups of Pellia: one composed of P. epiphylla, P. neesiana and P. borealis, the other of P. endiviifolia and P. megaspora. Furthermore, peroxidase isozyme patterns within the latter group even support the segregation of the European P. endiviifolia from Japanese accessions of the species, i.e., reveal three distinct taxa in the second group (Krzakowa, 1981).…”

“…(2) Are the species within Pelliaceae each monophyletic? (3) Is there genetic support for an infraspecific, geographical differentiation in P. endiviifolia as suggested (Krzakowa, 1981;Newton, 1981;Schuster, 1981)?…”

“…However, isozyme research, which has recently played an important role in solving some taxonomic problems in liverworts provide isoenzyme markers that allow to classify the critical forms correctly. These studies have given the solution to such problems as for example in the genus of Pellia Raddi (Krzakowa 1981;Odrzykoski et al 1996) Plagiochila (Dumort.) Dumort.…”

Two closely related species of the genus Barbilophozia: B. lycopodioides and B. hatcheri were studied in populations from the Tatra Range (S Poland), where they are frequent and widely distributed. Both species play an important role in plant communities and grow here very often side by side. Typically developed plants are quite easy to distinguish (even in the field), however morphologically intermediate forms, difficult to recognize by using of classical taxonomic methods, sometimes are found. We found enzymatic markers, that allow to recognize the critical forms. Both studied species are different in enzymatic patterns of glutamate oxaloacetate transaminase (GOT) and peroxidases (PX). In GOT four different phenotypes were detected. The first two (GOT 1 and GOT 2) were characteristic for B. hatcheri and next two (GOT 3 and GOT 4) for B. lycopodioides. Peroxidase patterns, that were monomorphic and specific for each species, exhibit different mobility in anodal and cathodal parts of gel. Results of the studies allowed us to draw the conclusion, that PX and GOT are good isoenzymatic markers and they can have practical application for identification of Barbilophozia species
