AbstractThe majority of the people present voted for having also in future a symposium on myxobacteria every year. To allow sufficient time for planning and raising funds, however, the place of the meeting should be decided upon 2 years in advance. The meeting should alternate regularly between both sidesof the Atlantic. An invitation has been extended by our colleagues in California to arrange the next meeting at the Asilomar Conference Grounds, Pacific Grove, California. The invitation was gratefully accepted, and July 25 to 27 was suggested as the most desirable time for the meeting. (This date has been verified in the meantime. H.R.) Ian Sutherland proposed that he would contact Colin Clarke and Howard Parish for chances to arrange the 1977 meeting in the United Kingdom. This was approved. The majority decided to restrict also future symposia on the biology of myxobacteria and to exclude other gliding bacteria. However, people from other fields of research may be invited to participate in the meeting. There was agreement not to publish a detailed symposium's report. Only the summaries of the lectures should be distributed. In order to be able to trace back quickly experimental strains to their origin, it was agreed upon to suggest for general adaption the labelling system which was proposed at the Cold Spring Harbor meeting: Each strain should be identified by the initials of the individual who isolated the strain or, if this is not feasable, who first introduced it into the literature. Furthermore, different strains of one species coming from one person should be numbered consecutively, the numbering beginning anew with another species; e.g. Myxococcus xanthus RBl, strains is independent of designations given the strain in individual laboratories, and should always remain attached to the name of the strain whenever anything is published about the strain and regardless who works with it later on. When a strain is sent to another individual, care should be taken to supply the original labelling with the strain. The complete history of the strain should be given when the strain is introduced into the literature for the first time. (Note added when writing down the Record: to avoid repeated labelling of one strain care should be taken to adopt as label the initials of the person who originally isolated and distributed the organism, for he might have sent the same strain to different laboratories. If necessary the label should be inquired from the original source of the strain. H.R.) Robert P. Burchard has been asked at the Cold Spring Harbor meeting to work out a system for the designation of mutants. His proposals have already been made public in the Myxobacterial Messenger. They were unanimously approved, suggested for general use, and may be cited here again: The system is based on that proposed by Demerec et al. (Genetics 54: 61 - 76, 1966). "Briefly, genus and species names should be followed by the initials of the describing investigator (first and last names). He or she would then assign a number to the strain, starting with 1. Each investigator should keep a log book with a list of his strains, their origin and history, and their genotype and/or phenotype. The latter could be accomplished with Demerec et al "3 letter plus" abbreviations. Using my strains as an example: M. xanthus RB1 derived from Dworkin's FB as a stable tan and called strain FB, to date. The phenotype nomenclature would be Tan-1. RB4 is my non-motile NM, derived from SM which in turn is derived from FB. The phenotype designation Cam-r25 means resistant to 25 ug chloramphenicol/ ml. For genotype, lower case lettering is used. Thus, a methionine-requiring auxotroph might be designated as "met-1". The hyphen could be replaced by a letter (capital ) when mapping is accomplished". It was again urged to make better use of the Myxobacterial Messenger (M.M.) to our mutual benefit. Completed Ph.D. theses on gliding bacteria should be reported to the M.M. and a brief abstract supplied. Planned gatherings of myxobacteria people at ASM meetings should be announced early in the M.M.. As already suggested at the Cold Spring Harbor meeting each laboratory should sent a list of available strains, including mutants, to the M.M.. At the Cold Spring Harbor meeting it has been suggested to start a central collection of all myxobacterial strains including mutants available. Martin Dworkin inquired in the meantime from Ellis Brockman if he would be willing and in a position to keep such a collection. This is not the case. Hans Reichenbach promised to ask at the Deutsche Sammlung von Mikroorganismen (German Collection of Microorganisms) in Göttingen whether they would be willing to accept such a collection. (Note added when writing down the Record: The policy of the Deutsche Sammlung von Mikroorganismen does not allow to keep such a specialized collection. H.R.).
