“…Indeed, Huang et al. ( 2019 ) noted that both Sphagnales and Andreaeales represent early diverging mosses based on an evolutionary trend of size reduction of the mitochondrial genome wherein Sphagnales and Andreaeales had relatively higher number of introns and longer intergenic spacers than derived mosses. This notion is further reinforced by our comparative analysis of mitochondrial genome sizes across 15 selected mosses (the same species used for phylogenetic analysis as in Figure 3 ), revealing that the mitochondrial genome size of A. regularis is 21.2 kb smaller than the average size of Sphagnopsida mitochondrial genomes and 13.7 kb larger than the average size of Bryopsida mitochondrial genomes ( Supplementary Table 1 ).…”

In the present study, we determined the complete mitochondrial genome of Andreaea regularis Müll. Hal. 1890, a lantern moss of the genus Andreaea Hedw. (Andreaeaceae). The A. regularis mitochondrial genome, with a total length of 118,833 bp, consists of 40 protein-coding genes, 3 ribosomal RNA genes, and 24 transfer RNA genes. A phylogenetic tree constructed with 19 complete mitochondrial genomes composed of liverworts, hornworts, and 15 mosses showed that Andreaeales formed the closest sister to Sphagnales before divergence of the remaining moss groups, indicating A. regularis being one of the earliest mosses. Our findings could be beneficial to investigate the bryophyte evolution.

“…To our knowledge, only one mitochondrial genome of the Andreaeales, that of A. wangiana , is available (Huang et al. 2019 ); this lineage split later than another moss lineage, the Sphagnales (Liu et al. 2019 ).…”

“…The repeats are present in mitogenomes of most basal species but absent in the species of terminal clades. A mitogenome size reduction during the evolution of mosses has recently been noted in the analysis of the Andreaea wangiana mitogenome [24]. The above-mentioned trends to miniaturization of the mitochondrial genome and loss of intergenic repeats may indicate a strong selection toward further stabilization of the genome structure in mosses.…”

The Mitochondrial Genome of Nematodontous Moss Polytrichum commune and Analysis of Intergenic Repeats Distribution Among Bryophyta

et al. 2021

An early-branched moss Polytrichum commune is a widely accepted model object for ecological, environmental, physiological, and genetic studies. Its mitochondrial genome has been sequenced and annotated. The genome contains 67 genes in total and has a length equal to 114,831 bp, which exceeds the length of most known mitochondrial genomes for mosses. A phylogenetic tree based on 33 coding sequences of mitochondrial genome was constructed, and the pairwise identity of whole mitogenome sequences was estimated for 44 Bryophyta species. Based on the analysis of pairwise identity, it was shown that mitogenomes of Tetraphis pellucida and Buxbaumia aphylla sufficiently differ from those of other Bryophyta species. The first known Bryophyta mitogenome rearrangement was identified in Pogonatum inflexum within Polytrichopsida. Based on the intergenic repeats occurrence in 44 bryophyte mitochondrial genomes and available data on repetitive elements content in other Viridiplantae groups, it was noted for the first time that greater stability of the moss’s mitogenomes is probably associated mainly with the absence of long (>1 kb) repeats. The phenomenon of absence of the intergenic repetitive elements in the terminal clades species was discovered.

Recent progress in sequencing technology and the increasing number of chloroplast genomes available in liverworts have greatly improved our understanding of not only genome structure and evolution, but also its phylogeny and evolution. However, the plastome resource of this group is still ineffective, as the plastomes have been sequenced from a small number of species. In the present study, two newly sequenced chloroplast genomes from liverworts, one from Pallavicinia longispina Stephani and the other from Pleurozia subinflata (Austin) Austin were reported. The former genome has a length of 122,410 bp, with GC content 36.90%, and the latter has a length of 118,441 bp, with GC content 32.22%. A total of 132 and 127 genes were determined in the plastomes of P. longispina and P. subinflata, respectively. Furthermore, 41 short sequence repeats (SSRs), 419 editing sites and 15 non-adjacent repeats in the plastome of P. longispina, and 65 SSRs, 288 editing sites, and nine non-adjacent repeats in the plastome of P. subinflata were detected. Valuable genomic resources for further research on liverwort phylogeny, evolution, and population genetics are provided from this study. Bangladesh J. Bot. 53(1): 109-113, 2024 (March)
