Phytochemical Components of Two Cyanobacterial Local Strains

A proposal for the unification of two cyanobacterial strains of Nostoc as the same species

The present research aimed to investigate through a polyphasic approach, the differences in morphological and genotypic features of two cyanobacterial strains isolated from paddy fields of northern parts of Iran, belonging to the family Nostocaceae (subsect. IV. I). Based on the reliable identification keys, the two strains were identified as Nostoc ellipsosporum (Desm.) Rabenh. ex Born. et Fla...

Draft Genome Sequences of Two Thermotolerant Cyanobacterial Strains Isolated from Hot Springs

We report here two draft cyanobacterial genome sequences, those of Cyanobacterium aponinum IPPAS B-1201, isolated from a hot spring in the Turgen Gorge (Kazakhstan), and the uncharacterized cyanobacterium IPPAS B-1203, isolated from a hot spring in Karlovy Vary (Czech Republic). These two strains were deposited at the Collection of Microalgae (IPPAS) of the Timiryazev Institute of Plant Physiol...

Plasmids from two morphologically distinct cyanobacterial strains share a novel replication origin.

A 2.9-kbp replication origin from a plasmid endogenous to the filamentous cyanobacterium Fremyella diplosiphon UTEX 481 was genetically characterized and sequenced. Deletion analysis of the 2.9-kbp DNA fragment delimited the minimum region necessary for replication in F. diplosiphon Fd33 to approximately 2.5 kbp. DNA sequence analysis revealed that the F. diplosiphon plasmid replication origin ...

Inference of parasite local adaptation using two different fitness components.

Estimating parasite fitness is central to studies aiming to understand parasite evolution. Theoretical models generally use the basic reproductive rate R(0) to express fitness, yet it is very difficult to quantify R(0) empirically and experimental studies often use fitness components such as infection intensity or infectivity as substitutes. These surrogate measures may be biased in several way...
