ABSTRACT The bases of the mycobacterial SOS box important for LexA binding were determined by replacing each base with every other and examining the effect on the induction of a reporter gene following DNA damage. This analysis revealed that the SOS box was longer than originally thought by 2 bp in each half of the palindromic site. A search of the Mycobacterium tuberculosis genome sequence with the new consensus, TCGAAC(N)4GTTCGA, identified 4 sites which were perfect matches and 12 sites with a single mismatch which were predicted to bind LexA. Genes which could potentially be regulated by these SOS boxes were ascertained from their positions relative to the sites. Examination of expression data for these genes following DNA damage identified 12 new genes which are most likely regulated by LexA as well as the known M. tuberculosis DNA damage-inducible genes recA, lexA, and ruvC. Of these 12 genes, only 2 have a predicted function: dnaE2, a component of DNA polymerase III, and linB, which is similar to 1,3,4,6-tetrachloro-1,4-cylcohexadiene hydrolase. Curiously, of the remaining 10 genes predicted to be LexA regulated, 7 are members of the M. tuberculosis 13E12 repeat family, which has some of the characteristics of mobile elements.

AbstractFrom a wild diploid species that is a relative of wheat, Aegilops speltoides, a 301-bp repeat containing 16 copies of a CAA microsatellite was isolated. Southern blot and fluorescence in situ hybridization revealed that ∼250 bp of the sequence is tandemly arrayed at the centromere regions of A- and B-genome chromosomes of common wheat and rye chromosomes. Although the DNA sequence of this 250-bp repeat showed no notable homology in the databases, the flanking or intervening sequences between the repeats showed high homologies (>82%) to two separate sequences of the gag gene and its upstream region in cereba, a Ty3/gypsy-like retroelement of Hordeum vulgare. Since the amino acid sequence deduced from the 250 bp with seven CAAs showed some similarity (∼53%) to that of the gag gene, we concluded that the 250-bp repeats had also originated from the cereba-like retroelements in diploid wheat such as Ae. speltoides and had formed tandem arrays, whereas the 300-bp repeats were dispersed as a part of cereba-like retroelements. This suggests that some tandem repeats localized at the centromeric regions of cereals and other plant species originated from parts of retrotransposons.
