TLDR
The first identification of an akinete marker gene is reported, which is likely to be involved in akinete formation inyanobacteria that form akinetes as well as heterocysts.Abstract:
Cyanobacteria that form akinetes as well as heterocysts present a rare opportunity to investigate the relationships between alternative differentiation processes and pattern formation processes in a single bacterium. Because no akinete marker gene has been identified, akinete formation has been little studied genetically. We report the first identification of an akinete marker gene.read more

TL;DR: This phylum-wide study highlights the benefits of diversity-driven genome sequencing, identifying more than 21,000 cyanobacterial proteins with no detectable similarity to known proteins, and foregrounds the diversity of light-harvesting proteins and gene clusters for secondary metabolite biosynthesis.

Compartmentalized function through cell differentiation in filamentous cyanobacteria
Enrique Flores,Antonia Herrero +1 more
TL;DR: This Review addresses cyanob bacterial intercellular communication, the supracellular structure of the cyanobacterial filament and the basic principles that govern the process of heterocyst differentiation.
Journal ArticleDOI
Cellular differentiation and the NtcA transcription factor in filamentous cyanobacteria.
TL;DR: The different features found in the NtcA-dependent promoters, together with the cellular level of active NTCA protein, should have a role in the determination of the hierarchy of gene activation during the process of heterocyst differentiation.

Cellular differentiation in the cyanobacterium Nostoc punctiforme
TL;DR: The regulatory circuits of three cellular differentiation events and symbiotic interactions of N. punctiforme can be experimentally analyzed by functional genomics and hypothesized to depart from the vegetative cell cycle following separate and distinct events.
Journal ArticleDOI
Proteomics combines morphological, physiological and biochemical attributes to unravel the survival strategy of Anabaena sp. PCC7120 under arsenic stress.
TL;DR: While up-regulated metabolic and antioxidative defense proteins, phytochelatin and GST work synchronously, the ars genes play a central role in detoxification and survival of Anabaena under As stress.

TL;DR: A new criterion for triggering the extension of word hits, combined with a new heuristic for generating gapped alignments, yields a gapped BLAST program that runs at approximately three times the speed of the original.

Multiple sequence alignment with hierarchical clustering
TL;DR: An algorithm is presented for the multiple alignment of sequences, either proteins or nucleic acids, that is both accurate and easy to use on microcomputers, based on the conventional dynamic-programming method of pairwise alignment.

Improved green fluorescent protein by molecular evolution using DNA shuffling.
TL;DR: The results demonstrate how molecular evolution can solve a complex practical problem without needing to first identify which process is limiting and envision that the combination of DNA shuffling and high throughput screening will be a powerful tool for the optimization of many commercially important enzymes for which selections do not exist.
