Small regulatory RNAs (sRNAs) are post-transcriptional regulators of bacterial gene expression. In cyanobacteria, the responses to nitrogen availability, that are mostly controlled at the transcriptional level by NtcA, involve also at least two small ...

Exploring the Diversity of the Thioredoxin Systems in Cyanobacteria
Cyanobacteria evolved the ability to perform oxygenic photosynthesis using light energy to reduce CO2 from electrons extracted from water and form nutrients.

With strikingly consistent patterns across three tropical forests, the authors find strong evidence for the promise of functional traits to provide mechanistic links between seedling form and demographic performance. Abstract Understanding the mechanisms that promote the coexistence of hundreds of species over small areas in tropical forest remains a ...

DNA methylation at tobacco telomeric sequences [PDF]
Majerová et al. (Plant Mol Biol, 2011) have recently reported that a considerable fraction of cytosines at tobacco telomeres is methylated. Although the data presented in this report indicate that tobacco telomeric sequences undergo certain levels of DNA

Glutaredoxins are essential for stress adaptation in the cyanobacterium Synechocystis sp. PCC 6803.
Glutaredoxin are small redox proteins able to reduce disulfides and mixed disulfides between GSH and proteins. Synechocystis sp. PCC 6803 contains three genes coding for glutaredoxins: ssr2061 (grxA) and slr1562 (grxB) code for dithiolic glutaredoxins ...

The Heterocyst-Specific Small RNA NsiR1 Regulates the Commitment to Differentiation in Nostoc
Heterocysts are specialized cells that filamentous cyanobacteria differentiate for the fixation of atmospheric nitrogen when other nitrogen sources are not available.

Thioredoxins (Trxs) are small, ubiquitous enzymes that catalyze disulphide–dithiol interchange in target enzymes. The large set of chloroplast Trxs, including f, m, x and y subtypes, use reducing equivalents fueled by photoreduced ferredoxin (Fdx) for ...
