Opis:: Fungal antagonist, Talaromyces flavus, is one of the most important biological agents of soil-borne fungal diseases including Verticillium and Fusarium wilt. In this study, to increase the effectiveness of T. flavus isolates obtained from greenhouse cucumbers and field grown tomatoes five chemical stabilizers were evaluated. Based on the results of previous studies, the most effective substrate for the growth, sporulation and stability of T. flavus isolates related to the above-mentioned plants was a mix of rice bran and peat-moss. Different chemical stabilizers were mixed with the above-mentioned substrate containing spore suspensions of various T. flavus isolates. For each plant, a completely randomized experiment was conducted under greenhouse conditions with seven treatments and three replications. The results of this study indicated that treatments containing sodium nitrate and D-cycloserine were more effective than those containing other stabilizers. The overall results of this study suggest that the use of some chemical stabilizers may enhance the biocontrol potential of fungal antagonists in controlling different plant diseases including Verticillium and Fusarium wilt.

Opis:: In this study, about 112 isolates of Streptomyces were isolated from chickpea rhizospheric soils. Among the isolated strains, five showed strong inhibitory effects against chickpea Fusarium wilt caused by Fusarium oxysporum f. sp. ciceris in vitro using plate assay and selected for further studies. The selected strains were identified as Streptomyces spp. based on morphological and biochemical characterization as well as 16S rDNA sequences analysis. Our results assigned them to strains related to genus of Streptomyces. In vitro, antagonistic effects of Streptomyces strains against the disease were evaluated through the dual-culture method, volatile and non-volatile metabolites, siderophore, protease and chitinase production. All bacterial strains inhibited mycelial growth of the pathogen ranging from 26 to 44.2% in dual culture assay. The non-volatile extract of five of the Streptomyces strains inhibited more than 50% growth of the pathogen, whereas volatile compounds were less effective on mycelial growth inhibition (20.2 to 33.4%). The ability of the biocontrol agents to produce siderophore and protease were varied, whereas, production of chitinase was detected for all strains. Results of the greenhouse assay indicated that all biocontrol agents reduced disease severity (ranging from 38.7 to 54.8%). Accordingly, strain KS62 showed higher control efficacy (54.8%). In addition, the biomass of chickpea plants (plant height and dry weight) significantly increased in plants treated with Streptomyces strains compared to non-bacterized control. The results of this study showed that it may be possible to manage chickpea Fusarium wilt disease effectively by using Streptomyces species, as biocontrol agents. Therefore, evaluating their efficiency under field conditions is needed.

Opis:: Verticillium wilt caused by Verticillium dahliae, is one of the most devastating diseases in pistachio orchards in the world including Iran. In search for an eff ective non-chemical strategy for the management of this disease, we evaluated the biocontrol potential of Trichoderma harzianum isolates obtained from the rhizosphere of healthy pistachio trees in diff erent locations of the Kerman province of Iran against V. dahliae under laboratory and greenhouse conditions. Dual culture tests in the laboratory were conducted in a completely randomized design using 72 T. harzianum isolates. Twenty isolates showed the highest in vitro antagonistic activity. Th e results indicated that all 20 isolates were capable of inhibiting the mycelial growth of V. dahliae signifi cantly. Among them, isolates Tr8 and Tr19 were the most eff ective by 88.89% and 85.12% inhibition, respectively. Extracted cell free metabolites of all eff ective isolates also inhibited the growth of V. dahliae in the culture medium signifi cantly. According to the results, isolates Tr4 and Tr6 inhibited fungal pathogen growth by 94.94% and 88.15% respectively, through production of non-volatile metabolites. In the evaluation of volatile metabolites, isolates Tr5 and Tr4 were the most eff ective by 26.27% and 24.49% growth inhibition, respectively. Based on the results of the in vitro experiments, the fi ve most eff ective isolates were selected for evaluation under greenhouse conditions for their biocontrol potential in controlling Verticillium wilt of pistachio. Results of the greenhouse, (in vivo) experiments were positive and indicated that the occurrence of wilt disease in plants treated with the antagonists alone or in combination with pathogenic fungus was lower than in plants inoculated with pathogen alone. Th e overall results of this study suggest that Trichoderma fungal antagonist may be an eff ective biocontrol agent for the control of Verticillium wilt of pistachio.

Opis:: Fusarium species are causal agents of fungal diseases occurring frequently in numerous agriculturally important plants, including potato, garlic and are one of the common pathogens of tomato, causing root rot in the west part of Iran. Therefore, the objectives of this study were to isolate and identify disease-causing Fusarium species from infected tomatoes based on the morphological and molecular characteristics. Twenty-five isolates of Fusarium were obtained from infected root of tomato plants collected from the fields in different regions of western Iran. Based on morphological features, the strains were classified into four following Fusarium species: F. oxysporum, F. redolens, F. proliferatum and F. verticillioides. The phylogenetic trees based on tef1 and tub2 dataset clearly distinguished closely related species. All of the isolates were evaluated for their pathogenicity on healthy tomato seedlings in the greenhouse. This is the first report on molecular identification of Fusarium species isolated from tomato plants cultivated in Iran.

Opis:: Jedną z najpoważniejszych chorób występujących na plantacjach lnu włóknistego jest fuzarioza wywoływana przez grzyb z rodzaju Fusarium. Przy silnym stopniu porażenia uprawy lnu przez fuzariozę plon słomy może obniżyć się do 60%, nasion do 80%. W kulturach pylnikowych włóknistego (Linum ustatissimum L.) otrzymano regeneranty, u których przeprowadzono obserwacje dziedziczenia odporności na fuzariozę w pokoleniach R2–R4. W tym celu założono wazonowe i polowe doświadczenia prowokacyjne. Jako inokulum infekcyjne użyto następujące gatunki grzybów: Fusarium oxysporum f.lini, Fusarium avenaceum, Fusarium culmorum, Fusarium gibbosum, Fusarium sambucinum i Fusarium poa. Dla odmiany Alba, średnio wrażliwej na fuzariozę, otrzymano linie regenerantów odpornych na tę chorobę. Najlepszą okazała się linia regeneranta Alba 1000, u której obliczono 88 % roślin zdrowych w wazonowym doświadczeniu prowokacyjnym, natomiast w testach polowych zawsze uzyskiwała ocenę 9, ponieważ na poletku występowały tylko rośliny zdrowe.
One of the most serious diseases found on flax plantations is fusariosis caused by a fungi from Fusarium genus. A strong contamination of flax crops may reduce the straw yield to 60% and seeds yield to 80%. Anther cultures of flax (Linum usitatissimum L.) allowed obtaining regenerated plants, in which the inheritance of resistance to Fusarium was observed in R2–R4 generations. The provocative flowerpot and field experiments were conducted for this purpose. The following fungi species were used as infectious inoculum: Fusarium oxysporum f.lini, Fusarium avenaceum, Fusarium culmorum, Fusarium gibbosum, Fusarium sambucinum and Fusarium poa. For an Alba variety, which was moderately susceptible, there were resistant lines of regenerated plants obtained. A line Alba 1000 turned out to be the best one as there was 88% of healthy plants in the provocative flowerpot experiment. The line got 9 score in the field experiments, because the plants were always healthy.

TB-566 tetra × N. alata) × N. alata were tested for resistance to TSWV. Tested plants were artificial inoculated with TSWV under greenhouse conditions. Out of 11 accessions of N. alata and N. sanderae 7 were found to be composed entirely of plants hypersensitive to TSWV. In the remaining four accessions there were from 16 to 25% of TSWV susceptible plants. The hybrids (N. tabacum cv. TB-566 tetra × N. alata) × N. alata, regardless of their cytogenetical status, showed hypersensitive response to inoculation with TSWV...

resistance to viral diseases
Opis:: Tobacco (Nicotiana tabacum L.) is an important industrial crop. Among the diseases causing losses in tobacco cultivation, viral ones are of particular importance due to the very low effectiveness of chemical protection allowing only for vector control. The greatest threat to tobacco cultivation in Poland and in many countries of the world is posed by potato virus Y (PVY), tomato spotted wilt virus (TSWV) and, in recent years, the increasingly frequent tobacco mosaic virus (TMV). The genetic resources studies carried out in the genus Nicotiana have shown a wide variation in species resistance, assessed biologically, serologically and molecularly, depending on the virus used and, in the case of PVY, also on the specific isolate. The results of the assessment of resistance in Nicotiana accessions presented in this paper, gathered from literature data as well as from our own research, allow us to broaden and systematise our knowledge on the sources of resistance to viral diseases. This is the only such an extensive study in this field. It provides an excellent information base for the appropriate selection of accessions for use in resistance breeding.

Opis:: Fusarium oxysporum f. sp. pisi (FOP) is a significant and destructive pathogen of field pea in Algeria. In the present study, 50 isolates of F. oxysporum f. sp. pisi, the causal agent of pea (Pisum sativum) wilt, collected from different parts of western Algeria and representing four races of the pathogen, were analyzed for virulence. The wilt incidence ranged from 6.66 to 88.33% on a highly susceptible cultivar (Little Marvel). Twenty-one isolates belonging to four races of FOP and one nonpathogenic F. oxysporum (FO) isolate were analyzed for vegetative compatibility in order to reveal the genetic structure of the population and to check the reliability of the method for the identification of physiological races of FOP. Obtained results showed that the FOP isolates could be classified into four main vegetative compatibility groups (VCGs) that corresponded to races l, 2A, 2B and 5. The race 6 isolate fell into the race 1 VCG. To our knowledge, this is the first such study in Algeria of its kind.
