phylogenetic analyses suggest reverse splicing spread of group i introns in fungal ribosomal dna.	group i introns have spread into over 90 different sites in nuclear ribosomal dna (rdna) with greater than 1700 introns reported in these genes. these ribozymes generally spread through endonuclease-mediated intron homing. another putative pathway is reverse splicing whereby a free group i intron inserts into a homologous or heterologous rna through complementary base-pairing between the intron and exon rna. reverse-transcription of the rna followed by general recombination results in intron spr ...	2005	16300679
phylogenetic position of yeastlike endosymbionts of anobiid beetles.	the anobiid beetles stegobium paniceum and lasioderma serricorne possess the intracellular yeastlike symbionts symbiotaphrina buchneri and symbiotaphrina kochii, respectively, in the mycetome between the foregut and midgut. the nucleotide sequences of the small-subunit rrna-encoding genes of the symbionts were determined for phylogenetic analysis. five group i introns were found in the small-subunit rrna-encoding genes of s. buchneri, but s. kochii lacked introns. the phylogenetic position of bo ...	1996	8572692
