Expansin proteins play a key role in inducing the extension and relaxation of plant cell walls. To understand the physiological role of expansins in lotus crop, Nelumbo nucifera Gaertn, during plant development, we cloned an expansin gene designated as NnEXPA1 using the rapid amplification of cDNA ends technique. The full-length cDNA of NnEXPA1 was 1,456 bp encoding a protein of 250 amino acids. Gene...
Up to now 17 alien species of family Naididae have been found in Poland. The majority of them have a Ponto-Caspian origin (Potamothrix hammoniensis, P. moldaviensis, P. heuscheri, P. vejdovskyi, P. bavaricus, P. bedoti, Psammoryctides barbatus, P. albicola, P. moravicus, Tubifex newaensis, Isochaetides michaelseni, Paranais simplex and P. frict). Moreover, North American (Quistadrilus multisetosus, Limnodrilus cervix...
The Aşaği Firat River is located in the south-eastern Anatolia, Turkey. The water quality of the Aşaği Firat River basin has been degrading for some time, primarily as the result of pollutants associated with the discharges from numerous domestic and agricultural point sources. Aquatic macroinvertebrate samples were collected from eight lakes conducted by using both hand-nets and an Ekman-Birge grab...
A qualitative survey of freshwater Oligochaeta was conducted in selected districts of Tamil Nadu, India, from October 2013 to June 2015. Thirteen taxa were recorded from a total of 1,915 specimens of freshwater Oligochaeta examined from various random samples. Out of the 13 taxa 10 were identified to the species level, two were identified to genus level and one only to subfamily level. These provided...
Embryogenic tissues of hybrid firs (Abies alba x A. cephalonica, Abies alba x A. numidica) have been cryopreserved using a slow-freezing method. The cryotolerance of six cell lines initiated from immature or mature zygotic embryos was tested. Following sorbitol (0.5 M) and DMSO (5%) pretreatments the samples were slowly frozen at a rate of 1 °C/min, plunged into liquid nitrogen and stored for 1 year...
Hydrogen peroxide (H2O2) plays versatile roles in various biological processes and in responses to stress in plants. To investigate effects of exogenous H2O2 on the transcript levels of some genes encoding antioxidative enzymes, such as superoxide dismutase Cu/Zn (Cu/ZnSOD), catalase (CAT) and ascorbate peroxidase (APX), and also on the ultrastructural alterations caused by lead, 7-day-old seedlings...
The enhanced expression of heat shock proteins (Hsps) in organisms is associated with environmental temperatures. For rainbow trout (Oncorhynchus mykiss), high temperature is a major abiotic stress limiting its growth and productivity. In the present study, we have investigated serum Cortisol (COR) and alkaline phosphatase (AKP) activity as well as Hsp40 and Hsp90β mRNA expression in different tissues...
Lamprodrilus isoporus (Michaelsen, 1901) inhabits Lake Baikal and some other lakes connected with it, and also occurs in northern Europe. The European population, described originally as L. isoporus f. variabilis Svetlov, 1936 does not differ much from the Siberian representatives. Typical habitat of the species is the cool and oxygen-rich profundal of oligotrophic lakes. In two Estonian shallow eutrophic...
In this paper, we described the clitellate fauna from an underwater hydrothermal vent zone in Frolikha Bay (Northern Baikal), where a unique community of oligochaetes dominate the zoobenthic communities. In total, twenty one oligochaete species were collected and of these, 19 species belong to the Naididae (former Tubificidae). In addition, one species belonging to the Propappidae, Propappus glandulosus...
Oligochaeta samples were collected from seven lakes (2 natural and 5 non-natural) of Ceyhan River basin during the summer and autumn seasons of 2014. The Ceyhan River basin is located in the south-eastern Anatolia region in Turkey. Lakes Gölbaşı and Azaplı are located in a protected area. Some physico-chemical parameters of surface water were measured in situ. Sampling for oligochaetes was conducted...
This work deals with the study of the oligochaete groundwater biodiversity in the Dinaric region, a karstic territory extending along the oriental shores of the Adriatic sea. Historical and new data depict a fauna of 123 species, 36 of which are stygobiotic. About 60% of the stygobionts are endemic to this region. Trichodrilus Claparède (Lumbriculidae) and Rhyacodrilus Bretscher (Rhyacodrilinae, Naididae)...
Aegilops searsii (2n = 2x = 14, SSSS), a wild relative of wheat, is a potentially important source of agriculturally useful genes for wheat breeding. The incorporation of Ae. searsii chromosome segments 1SS or 2SS into the wheat genome could significantly improve wheat flour quality and powdery mildew resistance, respectively. However, monitoring of wheat-Ae. searsii introgressions involving 1SS or...
This study was carried out in the Küçük Menderes River basin in order to determine the water quality and investigate the environmental quality and the applicability of both the Biological Monitoring Working Party (BMWP) and Average Score Per Taxon (ASPT). Monitoring took place in May, July and September 2014 at 10 stations (7 rivers and 3 lakes) according to the method of Intercalibration Common Metrics...
Investigating the microbial community structure and composition of toxic industrial wastes contaminated with nitrocellulose and various by-products is crucial for understanding the fate of these pollutants in the environment and for the development and application of effective bioremediation processes. In this study, we investigated the chemical properties and toxic potential of wastewater generated...
Lake Al-Delmage is part of the middle section of a main outfall drain located south of Baghdad (Iraq). This study focuses on the community structure of aquatic annelids and the physico-chemical variables in this lake. Six stations along the lake were chosen for sample collection in the period from January 2013 to January 2014. The results revealed that the lake water is oligohaline, with salinity...
Serum of mud crab, Scylla serrata had antibacterial activity against certain host specific bacteria as well as other known crustacean pathogenic bacteria. The respective antibacterial molecule was isolated by ion-exchange chromatographic method using diethylaminoethyl-cellulose matrix and eluted with gradient increase of sodium chloride (0–0.5 M). There were three major peaks on the elution profile...
In order to determine effects of different types of supplementary feed on the histology of liver and intestine of carp reared in a semi-intensive system, a six-month field experiment was carried out. Carp yearlings were fed different supplemental feeds: cereals (CF), pelleted (PF) and extruded (EF) compound feeds. Hepatocytes histomorphometry revealed larger nuclear profile area of EF-fed fish compared...
Ribosome-inactivating proteins (RIPs), a type of defensive chemicals, play key roles in host defense mechanisms against foreign pathogenic invaders and plant stress resistance. Alpha-momorcharin, a member of typical type I RIPs isolated from Momordica charantia, showed strongly antifungal, antitumor, and antibacterial activities both in vitro and in vivo. In this study, the expression level of alpha-momorcharin...
The essential oil composition and in vitro antioxidant activity of eight important betel vine landraces, such as Balia, Chandrakala, Dandabalunga, Desibangla, Godibangla, Karpada local, Maghai and Nahua were evaluated in this research. GC and GC-MS analysis of the essential oil resulted in identification of 50 compounds representing 95.97% of the oil. Major compounds were eugenol, terpinolene, terpinene,...
