Opis:: Various viral pathogens infect Cucurbitaceae and cause economic losses. Th e aim of the present study was to detect plant viral pathogens including Cucumber mosaic virus (CMV), Cucumber green mottle mosaic virus (CGMMV), Zucchini yellow mosaic virus (ZYMV), Cucurbit yellow stunting disorder virus (CYSDV) and Cucurbit chlorotic yellows virus (CCYV) in Lorestan province, in western Iran, and also to determine CMV genetic diversity in Iranian populations. A total of 569 symptomatic leaf samples were collected in 2013 and 2014 from cucurbits growing regions in Lorestan province. Th e collected samples were assessed for viral diseases by ELISA. Th e results showed virus incidences in most regions. Th en, the infection of 40 samples to CMV was confi rmed by RT-PCR. Moreover, to distinguish between the two groups (I and II) of CMV, PCR products were digested by two restriction enzymes XhoI and EcoRI. Results of the digestion showed that the isolates of Lorestan belonged to group I. Th e CMV-coat protein gene of eight isolates from diff erent regions and hosts was sequenced and phylogenetic analysis was performed. Subsequent analyses showed even more genetic variation among Lorestan isolates. Th e phylogenetic tree revealed that Lorestan province isolates belonged to two IA and IB subgroups and could be classifi ed together with East Azerbaijan province isolates. Th e results of the present study indicate a wide distribution of CMV, ZYMV, CGMMV, CYSDV and CCYV viruses in cucurbits fi elds of Lorestan province and for the fi rst time subgroup IB of CMV was reported on melon from Iran.

Opis:: Diosgenin (a steroidal saponin of fenugreek) has long been used as a raw substance for the manufacturing of steroid drugs. In order to evaluate the nutritional effect of different nitrogen (0, 50, 100, 150 and 200 kg ha-1) and copper (0, 10, 20 and 30 kg ha-1) doses on the diosgenin content, growth and yield of fenugreek (var. Ardestan), an experiment was carried out in a factorial arrangement based on complete randomized block design. The diosgenin content in the plant was monitored by a high performance liquid chromatography. Lower doses of copper increased yield, yield component and diosgenin content, but its higher level (30 kg ha-1) had negative effects on the plant yield. The simultaneous application of nitrogen and copper ameliorate the diosgenin production, yield and yield component. The result obtained from correlation and stepwise regression analysis showed that traits such as leaf area index, pods number per plant, and dry weight have significantly direct relation to diosgenin production levels in plants, while dry weight has the highest effect on diosgenin production compared to other traits. According the results, we also can conclude that nitrogen application can decrease copper toxicity in fenugreek in the contaminated soils.

Opis:: Fig mosaic virus (FMV) and Fig badnavirus-1 (FBV-1) are two of the most important fig infecting viruses. The incidence and distribution of FBV-1 and FMV were determined by testing in PCR 138 asymptomatic and symptomatic samples. These samples were collected from 60 fig gardens and agricultural fields in three provinces of Iran. The fig infecting viruses FBV-1 and FMV, respectively, were detected in 92 (66.6%) and 34 (24.6%) samples collected from all the surveyed fields. Overall, 24 out of 138 (17.3%) samples showed mixed infections. The sequence analysis of a genomic fragment of 922 nt, comprising the entire ORF-2 and part of the 5’ termini of the ORF-3 of 10 selected FBV-1 Iranian isolates from different provinces, and of the type member from GenBank (Acc. No: JF411989), showed a variation ranging from 1 to 3% at nucleotide level and 1% at the amino acid level. The phylogenetic analysis grouped the FBV-1 isolates into two groups, with the Iranian isolates clustered in two distinct subgroups of group I, according to their geographical origin. In our research, the prevalence and sequence analysis of FBV-1 as the only identified DNA virus infecting fig trees, was studied for the first time in Iran.

Opis:: Citrus bacterial canker (CBC) is one of the most important diseases of citrus. It is caused by Xanthomonas citri subsp. citri (Xcc). To investigate the variability of Xcc, a collection of twenty-five strains were isolated from the Fars, Hormozgan, Kerman and Sistan-va-Baluchestan provinces of Iran. The twenty-five strains were assessed phenotypically and genetically. These strains had similar biochemical properties. Based on host range determination, the strains were divided into two groups; the first group was pathogenic on Mexican lime (Citrus aurantifolia), citrumelo (Poncirus trifoliata x C. paradisi), citrange (C. sinensis x P. trifoliata) and sour orange (C. aurantium) varieties. The second group was pathogenic on Mexican lime only. Profile of cellular soluble proteins analyzed by sodium dodecyl sulphate-polyacryamid gel electrophoresis (SDS-PAGE) did not reveal any considerable differences among strains. Genetic diversity analyses were performed using two marker systems; repetitive polymerase chain reaction (rep-PCR) and random amplified polymorphic DNA (RAPD). The results of this research showed that two primers, ERIC 1R and 232, with the highest marker index, resulted in the most genetic variability among strains. Cluster analysis by band patterns showed that strains from the Sistan-va-Baluchestan province were a different group, so it was concluded that geographical origin of strains from the Sistan-va-Baluchestan province is different than the geographical origin of strains isolated from other provinces.

Opis:: Khulna is the third largest metropolitan city in Bangladesh and a centre with intensive commercial and industrial activities. Rapid urbanization and increased migration of people from rural and coastal areas has put tremendous pressure on its existing solid waste management. The status of the existing municipal solid waste (MSW) management tiers such as generation, source storage, collection, on-site storage, transportation, and open dumping has been identified in this study. The daily generation of MSW is estimated as 520 Mg, of which food and vegetable wastes are the main components (79% on average). The major source of generated MSW is residential areas, which is 85.87% of total generation, whereas 11.60% in commercial areas, 1.02% in institutional areas, 0.55% in street sweeps and 0.96% in other areas. About 50% of total generated waste is disposed daily to the dumping site and the rest remains uncollected and unmanaged. Non-governmental organizations and community based organizations play an important role in primary collection, composting of organic wastes and medical waste management.
