bop gene cluster expression in bacteriorhodopsin-overproducing mutants of Halobacterium halobium.

abstract：:Myxococcus xanthus dsp and dif mutants have similar phenotypes in that they are deficient in social motility and fruiting body development. We compared the two loci by genetic mapping, complementation with a cosmid clone, DNA sequencing, and gene disruption and found that 16 of the 18 dsp alleles map to the dif genes....
