Disease relevance of Marchantia

• Three of the sulfur-regulated genes in Synechococcus sp. strain PCC 7942 are similar to genes encoded by the chloroplast genome of the primitive plant Marchantia polymorpha [1].
• We cloned a 6.0-kb HindIII fragment from the cyanobacterium Plectonema boryanum using the chloroplast chlB (ORF513) gene of the liverwort (Marchantia polymorpha) as a probe [2].
• The ndhC and psbG genes overlap in the ptDNAs of maize, tobacco and Marchantia polymorpha, but are separated by a noncoding spacer in Synechocystis [3].

High impact information on Marchantia

• The Y chromosome in the liverwort Marchantia polymorpha has accumulated unique repeat sequences harboring a male-specific gene [4].
• A nicked group II intron and trans-splicing in liverwort, Marchantia polymorpha, chloroplasts [5].
• These four introns are absent in the liverwort Marchantia polymorpha, which carries a group I intron at an unrelated site in nad5 [6].
• We find the single Marchantia group I intron nad5i753 present as the only intervening sequence in both closely (Corsinia and Monoclea) and distantly related (Noteroclada, Bazzania, and Haplomitrium) liverwort genera [6].
• A mannose (Man)-binding lectin has been isolated and characterized from the thallus of the liverwort Marchantia polymorpha [7].

Biological context of Marchantia

• In the bryophyte Marchantia polymorpha this U residue is encoded in the mt genome and evolutionary studies suggest that restoration of a U28 residue is necessary when it is not encoded in the gene [8].
• Biotransformation of 4-androstene-3,17-dione by green cell suspension of Marchantia polymorpha: stereoselective reduction at carbon 17 [9].
• The potato (Solanum tuberosum L.) mitochondrial cox3/ sdh4 gene cluster was previously identified by heterologous hybridization using a Marchantia polymorpha sdh4 probe [10].

Anatomical context of Marchantia

• The sequence was found to be homologous to that of the nuclear-encoded 49 kDa complex I subunit of bovine and Neurospora mitochondria and to the sequence deduced from the mitochondrial nad7 gene identified in the mitochondrial (mt) DNA of tryp anosomes and the moss Marchantia [11].

Associations of Marchantia with chemical compounds

• Chalcone synthase-like gene in the liverwort, Marchantia paleacea var. diptera [12].
• New humulane-type sesquiterpenes from the liverworts Tylimanthus tenellus and Marchantia emarginata subsp. tosana [13].
• The sequence showed the typical distribution of cysteine residues found in bacterial-type ferredoxins and was highly homologous (91% homology) to that deduced from the chloroplast gene, frxA, of liverwort, Marchantia polymorpha [14].
• Light-enhanced ethylene production in Marchantia polymorpha L. [proceedings] [15].
• MpFAE3, a beta-ketoacyl-CoA synthase gene in the liverwort Marchantia polymorpha L., is preferentially involved in elongation of palmitic acid to stearic acid [16].

Gene context of Marchantia

• Identification of a novel nifH-like (frxC) protein in chloroplasts of the liverwort Marchantia polymorpha [17].
• The major difference is a larger inverted repeat than that of the liverwort Marchantia, Anthoceros contains an excess of ndhB and rps7 genes and the 3' exon of rps12 [18].
• The anticodon of the tRNA(Lys) gene (trnK) in the liverwort, Marchantia polymorpha, was artificially converted to an amber anticodon [19].
• Interorganellar gene transfer in bryophytes: the functional nad7 gene is nuclear encoded in Marchantia polymorpha [20].
• Significantly different substitution rates were found between leafy/simple thalloid and complex thalloid liverwort taxa, with rates of rbcL sequence evolution in leafy/simple thalloid taxa being higher and more indicative of those of vascular plants, and with those of complex thalloid taxa (such as Marchantia) being slower [21].
