Glazer and L. Packer, eds., 1988). Having surveyed the current state of affairs, they think it is titre to try to standardize the narenclature of cyanobacterial genes. With this in mind they have proposed the follOlling rules: (1) Gene designations proposed for Escherichia coli and/or Bacillus subtilis must be used W1enever possible. (2) For functions specifically related to photosynthesis, gene designations erployed for photosynthetic bacteria or plants can be used. (3) Designations already in use for bacterial genes must be avoided if the cyanobacterial gene products have not been identified or are functionally different fran those previously published. (4) Genes that are involved in the fonnation of multinnlecular caqJlexes (structure, asserbly, and/or regulation) or that are part of a given tretabolic pattway can be designated by different capital letters appended to a uniq..ie three l~r-case letter root. The follOlling are given as exarples: ~to~ - genes related to allophycocyanin ~ to atpZ - genes related to the ATPase caqJlex ~to~ - genes related to phycocyanin ~ to ~ - genes related to phycoerythrin tretA to tretZ - genes related to the trethionine biosynthetic pattMay nifA to nitz - genes involved in nitrogen fixation psaA to psaZ - genes related to photosystan I psbl\ to psbZ - genes related to photsystan II (5) Arabic nuirerals follOlling a gene designation are used to identify the various copies within a multi gene f c111il y (e.g. , psbl\l , psbl\2, psM'.3, ... ) . (6) The allele nurbers of a given locus must be identified by arabic nuirerals preceded by a hyphen (e.g. atpl\-1, cpc:B2-l, psl:iH-3), ••• ). LIST OF CYPIDW:TERIAL REFEROCES FOO 1~ AVAILABLE If your appetite for cyanobacteri al references is unsated, then you' 11 be happy to hear that JEFF ELHAI has made available a (nearly) exhaustive list of 1~ references concerning cyanobacteria in jour nals covered by Science Citation Index.

FIDTOSYSTEJ,1 II l:XHR D (JW Z?) IcmTIFIED WIM VEmGAS tells us a tale of a recent discovery. For years, Z, the donor to the Photosysten II (PSII) reaction center, and D, an oxidizable PSII carponent structurally resenbling Z, \\ere assured to be plastoquinols. This ass1.1Tption rested essentially on a variety of EPR and~ rreasurerents made on the oxidized donors. lbt.ever, the observed stoichiaretry of extractable plastoquinone and other PSII can- ponents could not account for Zand D. So w,at, in fact, is Zand D? Independently, Gerry Babcock, Bridgette Barry, Rick Debus, and Lee McIntosh at Michigan State University and Vennaas' group at Arizona State University considered the pos sibility that Z and D instead of (1.linols \\ere tyrosyl residues in 01 (encoded by pshl\) and 02 (pstfl).
