Notes for genera: basal clades of Fungi (including Aphelidiomycota, Basidiobolomycota, Blastocladiomycota, Calcarisporiellomycota, Caulochytriomycota, Chytridiomycota, Entomophthoromycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota, Mucoromycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota and Zoopagomycota)

Compared to the higher fungi (Dikarya), taxonomic and evolutionary studies on the basal clades of fungi are fewer in number. Thus, the generic boundaries and higher ranks in the basal clades of fungi are poorly known. Recent DNA based taxonomic studies have provided reliable and accurate information. It is therefore necessary to compile all available information since basal clades genera lack updated checklists or outlines. Recently, Tedersoo et al. (MycoKeys 13:1--20, 2016) accepted Aphelidiomycota and Rozellomycota in Fungal clade. Thus, we regard both these phyla as members in Kingdom Fungi. We accept 16 phyla in basal clades viz. Aphelidiomycota, Basidiobolomycota, Blastocladiomycota, Calcarisporiellomycota, Caulochytriomycota, Chytridiomycota, Entomophthoromycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota, Mucoromycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota and Zoopagomycota. Thus, 611 genera in 153 families, 43 orders and 18 classes are provided with details of classification, synonyms, life modes, distribution, recent literature and genomic data. Moreover, Catenariaceae Couch is proposed to be conserved, Cladochytriales Mozl.-Standr. is emended and the family Nephridiophagaceae is introduced

EF-G catalyzes tRNA translocation by disrupting interactions between decoding center and codon-anticodon duplex.

During translation, elongation factor G (EF-G) catalyzes the translocation of tRNA2-mRNA inside the ribosome. Translocation is coupled to a cycle of conformational rearrangements of the ribosomal machinery, and how EF-G initiates translocation remains unresolved. Here we performed systematic mutagenesis of Escherichia coli EF-G and analyzed inhibitory single-site mutants of EF-G that preserved pretranslocation (Pre)-state ribosomes with tRNAs in A/P and P/E sites (Pre-EF-G). Our results suggest that the interactions between the decoding center and the codon-anticodon duplex constitute the barrier for translocation. Catalysis of translocation by EF-G involves the factor's highly conserved loops I and II at the tip of domain IV, which disrupt the hydrogen bonds between the decoding center and the duplex to release the latter, hence inducing subsequent translocation events, namely 30S head swiveling and tRNA2-mRNA movement on the 30S subunit
