TL;DR: Evidence of molecular diversity of cyanobacteria in Antarctica that is much greater than the diversity currently known based on traditional microscopic analysis is provided and decisive arguments concerning the global geographic distribution of Cyanobacteria should therefore incorporate data obtained with the molecular tools described here.

TL;DR: In general, the strains closely related at the 16S rRNA gene level belonged to the same morphospecies, Nevertheless, divergences were observed concerning the diversity in terms of species richness, novelty, and geographical distribution.

TL;DR: For the first time, the cyanobacterial diversity from microbial mats in lakes of Eastern Antarctica was investigated using microscopic and molecular approaches as mentioned in this paper, and the results indicated that potential Antarctic endemic species, including a previously undiscovered diversity, are more abundant than has been estimated by morphological methods.

TL;DR: This work resulted in the construction of an improved broad-host-range replicon derived from RSF1010, which replicates in several phylogenetically distinct strains including a new experimental model strain Synechocystis sp.

TL;DR: An investigation targeting the cellular proteomic expression of the heterocysts compared to vegetative cells of a population cultured under N2-fixing conditions and identified 506 proteins, where 402 had confident quantifications.
