Abstract Genetic tools derived from the Cas9 RNA-guided nuclease are providing essential capabilities to study and engineer bacteria. While importance of off-target effects was noted early in Cas9’s application mammalian cells, cleavage by bacterial genomes is easily avoided due their smaller size. Despite this, several studies have reported experimental setups which expression toxic, even when using catalytic dead variant (dCas9). Specifically, dCas9 shown be toxic complex with guide RNAs...
Marine Synechococcus cyanobacteria are major contributors to global oceanic primary production and exhibit a unique diversity of photosynthetic pigments, allowing them exploit wide range light niches. However, the relationship between pigment content niche partitioning has remained largely undetermined due lack single-genetic marker resolving all types (PTs). Here, we developed employed robust method based on three distinct genes ( cpcBA , mpeBA mpeW ) estimate relative abundance known PTs...
Synechococcus cyanobacteria are ubiquitous and abundant in the marine environment contribute to an estimated 16% of ocean net primary productivity. Their light-harvesting complexes, called phycobilisomes (PBS), composed a conserved allophycocyanin core, from which radiates six eight rods with variable phycobiliprotein chromophore content. This variability allows cells optimally exploit wide variety spectral niches existing ecosystems. Seven distinct pigment types or subtypes have been...
Numbering in excess of 10 million per milliliter water, it is now undisputed that aquatic viruses are one the major factors shaping ecology and evolution Earth's microbial world. Nonetheless, environmental viral diversity roles remain poorly understood. Here we report first thorough characterization a virus (designated TsV) infects coastal marine microalga Tetraselmis striata. Unlike previously known microalgae-infecting viruses, TsV small (60 nm) DNA virus, with 31 kb genome. From range...
Abstract All characterized members of the ubiquitous genus Acaryochloris share unique property containing large amounts chlorophyll (Chl) d , a pigment exhibiting red absorption maximum strongly shifted towards infrared compared to Chl . is major in these organisms and notably bound antenna proteins structurally similar those Prochloron Prochlorothrix Prochlorococcus only three cyanobacteria known so far contain mono- or divinyl-Chl b as pigments lack phycobilisomes. Here, we describe...
Significance Of all cyanobacteria on Earth, marine Synechococcus are those displaying the greatest pigment diversity. The most sophisticated type is cells able to reversibly modify their color by a phenomenon called IV chromatic acclimation or CA4. Two genetically distinct CA4 types (CA4-A and CA4-B) have evolved in different lineages. Together, they represent almost half of oceanic areas equally abundant but occupy complementary ecological niches. While molecular mechanism CA4-A has...
A bstract The Theory of Island Biogeography (TIB) promoted the idea that species richness within sites depends on site connectivity, i.e. its connection with surrounding potential sources immigrants. TIB has been extended to a wide array fragmented ecosystems, beyond archipelagoes, surfing analogy between habitat patches and islands patch-matrix framework. However, patch connectivity often little contributes explaining in empirical studies. Before interpreting this trend as questioning broad...
