TLDR
This review focuses on akinetes of Nostocales, emphasizing environmental triggers and cellular responses involved in differentiation, maturation, dormancy, and germination of these resting cells and special attention is given to genetic regulation of the differentiation process.Abstract:
Cyanobacteria are an ancient and morphologically diverse group of photosynthetic prokaryotes, which were the first to evolve oxygenic photosynthesis. Cyanobacteria are widely distributed in diversed environments. In the case of members of the orders Nostocales and Stigonematales, their persistence and success were attributed to their ability to form specialized cells: heterocysts, capable of fixing atmospheric nitrogen and spore-like cells, the akinetes. This review focuses on akinetes of Nostocales, emphasizing environmental triggers and cellular responses involved in differentiation, maturation, dormancy, and germination of these resting cells. Morphological and structural changes, variation in akinete composition, and metabolism are summarized. Special attention is given to the genetic regulation of the differentiation process in an attempt to close gaps in our understanding of the dormancy phenomenon in cyanobacteria and to identify open questions for future research.read more

Identification of novel toxin-producing cyanobacteria in Iowan lakes
TL;DR: This study focused analytical efforts on lesser studied toxins (anatoxin-a, cylindrospermopsin, and saxitoxin) and aimed to isolate and identify cyanobacteria that produce these cyanotoxins in Iowan lakes.

Bacteria-phage coevolution with a seed bank
TL;DR: In this paper , a factorially designed experiment was conducted to test the hypothesis that, by generating a seed bank of protected individuals, dormancy can modify the patterns and processes of antagonistic coevolution.

The Molecular Biology of Cyanobacteria
TL;DR: This work focuses on the study of the structure and function of the Photosystem II Reaction Center in Cyanobacteria, which consists of Chloroplast Origins and Evolution, and its role in the Evolution of the Universal Enzyme.

The role of vitrification in anhydrobiosis.
TL;DR: Evidence is presented here showing that trehalose has a remarkably high glass-transition temperature (Tg), which makes this sugar useful in stabilization of biomolecules of use in human welfare and may explain the stability and longevity of anhydrobiotes that contain it.
