Samples were collected in July and October 2003 and in January and April 2004 from 3 stations through horizontal tows using a plankton net. After the analysis of plankton samples, 123 species that belong to 5 classes were identified. It was determined that one species (Phalacroma cuneus Schutt, 1895) was a new record for Turkish waters. The species composition mostly consisted of dinoflagellates (53.7%) which were followed by diatoms (43.9%). Most of the species which were identified in this study were similar to those phytoplanktonic algal species which were reported from the Eastern Mediterranean Sea in previous studies. These are neritic, oceanic, temperate and subtropical climate species. It was detected that 10 out of 19 potentially harmful algal species identified in this study were toxic species; however, they did not show an extreme increase. Dinophyceae had the highest cell number in July (1100 cell/L, St.1) and Bacillariophyceae in April (2280 cell/L, St.2). The environmental variables of the seawater such as temperature (13.0-26.5 oC), salinity (35.9-38.5‰) and dissolved oxygen (4.43-8.46 mg/L) were measured in every sampling period. Consequently, the phytoplankton species and their abundances in the Gulf of Edremit were firstly determined with this study, and phytoplankton composition representing oligotrophic sea water characteristic in the Aegean Sea was obtained.","PeriodicalId":14521,"journal":{"name":"IUFS Journal of Biology","volume":"44 1","pages":"31-46"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87884411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 20 full length of Dicer like proteins (DCL1, DCL2, DCL3 and DCL4) from different organisms available in NCBI were evaluated by bioinformatics tools to investigate properties, structure of DCLs, domain analysis, multiple sequence alignment and phylogenetics tree construction. All DCLs protein sequences have Ribonuclease III protein family that contains RNaseIII domain including Helicase ATP-binding type-1, Helicase C-terminal, Dicer double-stranded RNA-binding fold, PAZ, Ribonuclease III, Double stranded RNA-binding domain (dsRB). Physicochemical analysis offers data such as pI, EC, Al, GRAVY and instability index about these enzymes. Putative phosphorylation sites were also identified which are found to be conserved in plant species and the results showed that the most abundant phosphorylation site is Serine residues in DCLs proteins. Patterns and profile analysis were performed using Prosite and conserved protein motifs subjected to MEME to obtain the best possible matches. The phylogenetics tree represented three major clusters and similar DCLs protein sequences of different plant species clustered together. The obtained results could be used for further in silico analysis and homology modeling studies.

From the 15 th day on, some of the seedlings from the control and the experimental groups were kept in a horizontal position, and senescence process of the cotyledons of these seedlings was observed. Applications of eBL (especially 10 -9 M) were found to have induced senescence both in horizontally and vertically positioned plants. When it was applied with TIBA, a marked delay of senescence was noted in the lower cotyledons of the horizontally positioned plants. Total chlorophyll and protein amounts and peroxidase activity were determined. In case brassinosteroids are applied with TIBA, they do not affect senescence, implying that they accelerate senescence in the presence of auxin. Since auxin is distributed asymmetrically, eBL and auxin accumulated in the lower cotyledons may lead to accelerated senescence. This study showed that eBL and auxin may act as a senescence signal in the vertically and horizontally positioned seedlings, and earlier death of the lower cotyledons than the upper ones may be a result of asymmetrical auxin distribution. In this study, it was revealed that promoting effect of eBL on senescence occured only in the presence of auxin.

Application of SA and IAA activate the production of proline and soluble proteins in tomato roots, where their levels were more pronounced in the infected than the healthy plants. Moreover, both elicitors increased the levels of phenolics and flavonoids accompanied by stimulations in the activities of phenylalanine ammonia lyase (PAL), peroxidase (POX) and polyphenol oxidase (PPO) in tomato roots, where the magnitude of induction were more obvious in infected plants than healthy one. Also, microscopic examination revealed the anatomical differences observed in both untreated healthy and infected plants as well as in plants treated with SA and IAA. The present results indicate the effectiveness of SA and IAA in enhancing resistance of tomato to retard the incidence of infestation by Orobanche. These biochemical and histological changes involved in plant defense mechanisms may be one of the basic ways participate in the action of SA and IAA for increasing resistance in tomato against Orobanche ramosa .

Sampling was performed in seven locations in Izmir (Bornova, Buca, Cesme, Foca, Karsiyaka, Konak and Tire) in autumn and summer of 2009. Totally 192 isolates were obtained from the air and surface samples of these places. Air samples were collected using a MAS-100 Microbial Air Sampler (Merck) and fungal load were detected by using Rose Bengal Chloramphenicol Agar (RBCA, Merck). Biofilm samples were obtained from different surfaces (stone, wood, plaster, marble, limestone, brick and paint). As a result of our study, 25 genera related to Zygomycota , anamorph Ascomycota and teleomorph Ascomycota were identified. Besides, Aspergillus sp., Penicillium sp., Phoma sp., Alternaria sp., Chaetomium sp. and Cladosporium sp. were appeared the most frequently fungi genera. However, 6 isolates were not identified. It was observed that Aspergillus sp. was at the first stage with frequency of 21.88% while Penicillium sp. was at the second stage with 17.70%. In our study it was also shown that fungal load was much more in autumn than in summer due to its high moisture content and optimum temperature.

To evaluate the antibacterial and hemolitic activities of extracts standard antibiotic discs and human erythrocytes were used, respectively. The antibacterial activity was determed in the all extracts, except the hexane extracts of the leaves. It was observed that Bacillus subtilis ATCC 6633, Legionella pneumophila ATCC 33152 and L. pneumophila serogroup (SG) 2-14 are the most susceptible bacteria to the different extracts, while Pseudomonas aeruginosa ATCC 9327, Staphylococcus aureus ATCC 6538, Enterococcus faecalis ATCC 10541 and Proteus mirabilis are resistant bacteria. It was determined that chloroform (leaf and stem), hexane (leaf) and deionized water (stem) extracts did not show hemolytic activity, while ethanol (leaf) (â‰¥5 mg/ml), methanol (stem and leaf) (â‰¥10 mg/ml), acetone (leaf) (â‰¥10 mg/ml) and deionized water (leaf) (â‰¥20 mg/ml) extracts showed hemolytic activity.
