Copper effect on cytochrome b559 of photosystem II under photoinhibitory conditions
(Wiley, 2004)
Toxic Cu (II) effect on cytochrome b559 under aerobic photoinhibitory conditions was examined in two different photosystem II (PSII) membrane preparations active in oxygen evolution. The preparations differ in the content ...

Chromosomal translocations caused by either Pol32-dependent or Pol32-independent triparental break-induced replication
(American Society for Microbiology, 2009)
Double-strand breaks (DSBs) are harmful DNA lesions that can generate chromosomal rearrangements or chromosome losses if not properly repaired. Despite their association with a number of genetic diseases and cancer, the ...

Heterocyst development and diazotrophic metabolism in terminal respiratory oxidase mutants of the cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2007)
Heterocyst development was analyzed in mutants of the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120 bearing inactivated cox2 and/or cox3 genes, encoding heterocyst-specific terminal respiratory oxidases. ...

Open reading frame all0601 from Anabaena sp. strain PCC 7120 represents a novel gene, cnaT, required for expression of the nitrate assimilation nir operon
(American Society for Microbiology, 2003-09)
Expression of the nitrate assimilation nir operon in the filamentous, heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120 requires the action of both the global nitrogen control transcription factor NtcA and the ...

Pneumocystis jirovecii transmission from Immunocompetent carriers to infant
(2008)
We report a case of Pneumocystis jirovecii transmission from colonized grandparents to their infant granddaughter. Genotyping of P. jirovecii showed the same genotypes in samples from the infant and her grandparents. These ...
