Emp24 is a member of the p24 protein family, which was initially localized to the endoplasmic reticulum, Golgi and COP vesicles, but has recently shown to be associated with Saccharomyces cerevisiae peroxisomes as well. Using cell fractionation and electron- and fluorescence microscopy, we show that in the yeast Hansenula polymorpha, Emp24 also associates with peroxisomes. In addition, we show ...

The presence of microplastics (MPs) in several components different ecosystems has aroused great concern and led to numerous studies on MP pollution. Although there been an increasing number these aquatic ecosystems, no data about the pollution zebra mussel (Dreissena polymorpha, Pallas 1771) living Beyhan dam lake (Elaz??, Türkiye) are available. This study aimed investigate MPs freshwater spe...

In budding yeast Saccharomyces cerevisiae, the peroxisomal protein Inp2 is required for inheritance of peroxisomes to the bud, by connecting the organelles to the motor protein Myo2 and the actin cytoskeleton. Recent data suggested that the function of Inp2 may not be conserved in other yeast species. Using in silico analyses we have identified a weakly conserved Inp2-related protein in 18 spec...

In this study, some biochemical responses of Cyfluthrin (CFT), a commercial insecticide in Dreissena polymorpha, were investigated. The 96 hour LC50 value CFT on D. polymorpha was calculated as 553.22 ± 27.3 µg / L. exposed to subletal concentrations (1/20, 1/10 and 1/5 value) for 24 hours. enzyme activities superoxide dismustase (SOD), catalase (CAT) glutathione peroxidase (GPx) determined ind...

The preliminary result of a survey conducted on Xylaria species in the North of Iran is presented. Based on morphological examination of fungal specimens collected from Guilan, Mazandaran and Golestan provinces, eight species including Xylaria arbuscula, X. cubensis, X. filiformis, X. hypoxylon, X. longipes, X. multiplex, X. pannosa, and X. polymorpha were identified. Among the identified speci...

A collection of nodule isolates from Medicago polymorpha obtained from southern and central Portugal was evaluated by M13-PCR fingerprinting and hierarchical cluster analysis. Several genomic clusters were obtained which, by 16S rRNA gene sequencing of selected representatives, were shown to be associated with particular taxonomic groups of rhizobia and other soil bacteria. The method provided ...

Byssally tethered mussels are found in a variety of habitats, including rocky intertidal, salt marsh, subtidal, and hydrothermal vents. One key to the survival of mussels in these communities is a secure attachment, achieved by the production of byssal threads. Although many studies have detailed the unique biomechanical properties of byssal threads, only a few prevalent species have been exami...

Aneura mirabilis is a parasitic liverwort that exploits an existing mycorrhizal association between a basidiomycete and a host tree. This unusual liverwort is the only known parasitic seedless land plant with a completely nonphotosynthetic life history. The complete plastid genome of A. mirabilis was sequenced to examine the effect of its nonphotosynthetic life history on plastid genome content...

Nucleotide sequence of the psbK gene of the cyanobacterium Synechocystis 6803 The psbK gene is found in chloroplast, cyanelle and cyanobacterial genomes (1-3). It encodes a low molecular weight photosystem H-associated polypeptide (1). This gene is closely linked to the psbl gene in chloroplast genomes. We have previously reported the isolation and restriction mapping of a Synechocystis 6803 AE...
