CytR Homolog of subsp. Controls Air-Liquid Biofilm Formation by Regulating Multiple Genes Involved in Cellulose Production, c-di-GMP Signaling, Motility, and Type III Secretion System in Response to Nutritional and Environmental Signals.

subsp. [Pcc (formerly subsp. )] PC1 causes soft-rot disease in a wide variety of plant species by secreting multiple pathogenicity-related traits.

Interaction of Bacterial Membrane Vesicles with Specific Species and Their Potential for Delivery to Target Cells.

Membrane vesicles (MVs) are secreted from a wide range of microbial species and transfer their content to other cells. Although MVs play critical roles in bacterial communication, whether MVs selectively interact with bacterial cells in microbial communities is unclear. In this study, we investigated the specificity of the MV-cell interactions and evaluated the potential of MVs to target bacterial cells for delivery.

Expression and Function of Different Guanine-Plus-Cytosine Content 16S rRNA Genes in at Different Temperatures.

The halophilic archaeon harbors three ribosomal RNA (rRNA) operons (, , and ) that contain the 16S rRNA genes , , and , respectively. Although and () have almost identical sequences, the and sequences differ by 5.4%, and they differ by 2.

Diversity in Biosynthetic Pathways of Galactolipids in the Light of Endosymbiotic Origin of Chloroplasts.

Cyanobacteria and chloroplasts perform oxygenic photosynthesis, and share a common origin. Galactolipids are present in the photosynthetic membranes of both cyanobacteria and chloroplasts, but the biosynthetic pathways of the galactolipids are significantly different in the two systems. In this minireview, we explain the history of the discovery of the cyanobacterial pathway, and present a probable scenario of the evolution of the two pathways.
