Identification and partial characterization of antifungal and antibacterial activities of two Bacillus sp. strains isolated from salt soil in Tunisia [PDF]
Two Bacillus sp. strains (B29 and B27) isolated from soil in the South of Tunisia were tested for their abilities to produce antimicrobial compounds. Both strains showed antimicrobial activity against Gram-positive and Gram-negative bacteria, yeasts and ...

A preliminary phylogeographic study of Flavopunctelia and Punctelia inferred from rDNA ITS-sequences [PDF]
A preliminary phylogeny of the genera Flavopunctelia and Punctelia is presented. Genus and species delimitations have been investigated using ITS rDNA-sequencing of populations from different continents.

Nuclear ribosomal internal transcribed spacer (ITS) sequences were sequenced for 23 species and subspecies of Elymus sensu lato collected in Russia. The Neighbor-Net analysis of ITS sequences suggested that there are four ribotypes called Core Northern ...

Genome-wide profiling of chromosome interactions in Plasmodium falciparum characterizes nuclear architecture and reconfigurations associated with antigenic variation. [PDF]
Spatial relationships within the eukaryotic nucleus are essential for proper nuclear function. In Plasmodium falciparum, the repositioning of chromosomes has been implicated in the regulation of the expression of genes responsible for antigenic variation,

macroH2A1 histone variant represses rDNA transcription
The regulation of ribosomal DNA transcription is an important step for the control of cell growth. Epigenetic marks such as DNA methylation and posttranslational modifications of canonical histones have been involved in this regulation, but much less is known about the role of histone variants.

Cryptic Species: A Mismatch between Genetics and Morphology in Millepora [PDF]
Millepore morphology is highly variable and shows signs of phenotypic plasticity. Two species of Millepora are present around the islands of the Bahamas: one exhibiting a strong, blade-like structure, Millepora complanata, and the other having a delicate

Viability of Giardia intestinalis cysts : assessing viability under environmental conditions : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Microbiology at Massey University, Palmerston North, New Zealand [PDF]
Much work has been put into the detection and monitoring of Giardia, but once found, it is not easy to tell whether the cysts are viable and thus infective.

Transcription and methylation of flax rDNA
The transcription of flax rDNA and the processing of the rRNA precursors is described. The location of methylated regions of the rDNA has been assayed, one of the least methylated regions maps close to the 5' end of the largest identified rRNA precursor.

Methanogenic \u3cem\u3eArchaea\u3c/em\u3e and human periodontal disease [PDF]
Archaea have been isolated from the human colon, vagina, and oral cavity, but have not been established as causes of human disease. In this study, we reveal a relationship between the severity of periodontal disease and the relative abundance of archaeal

Dating the cyanobacterial ancestor of the chloroplast [PDF]
Cyanobacteria have played a pivotal role in the history of life on Earth being the first organism to carry out oxygenic photosynthesis, which changed atmospheric chemistry and allowed the evolution of Eukarya.
