Microevolution toward loss of photosynthesis: Mutations promoting dark-heterotrophic growth and suppressing photosynthetic growth in cyanobacteria

The paper reports mutations in cyanobacteria that lead to loss of photosynthetic growth and promote dark-heterotrophic growth through a single gene mutation.

Restoration of the Functional nif Gene Cluster by Seven Excision and Two Inversion Events during Heterocyst Development in the Nitrogen-Fixing Cyanobacterium Calothrix sp. NIES-4101

The paper identifies a complex recombination process involving seven excision and two inversion events that restores the fragmented nif gene cluster in Calothrix sp. NIES-4101 during heterocyst development.

Genome sequence and cell biological toolbox of the highly regenerative, coenocytic green feather alga Bryopsis

This paper presents the genome sequence of Bryopsis, a coenocytic green alga, and identifies gene duplications and unique features that may underlie its regeneration ability.

Deciphering the Genomes of Motility-Deficient Mutants of Vibrio alginolyticus 138-2

This study identifies mutations in flagella-related genes in motility-deficient Vibrio alginolyticus mutants through genomic analysis.

The dgc2 gene encoding di-guanylate cyclase suppresses both motility and biofilm formation in the filamentous cyanobacterium Leptolyngbya boryana.

This study identifies the dgc2 gene in Leptolyngbya boryana, showing that its inactivation suppresses motility and enhances biofilm formation, revealing a novel role for c-di-GMP in colony pattern formation.
