“…Among these enzymes, increased activities of chitinases and peroxidases (PO) have been implicated in the mechanism of induced systemic resistance (ISR) in cucumber (Rasmussen et al 1995;Elsharkawy et al 2012b). The expression of hydrolases and oxidases is influenced by accumulation of callose, lignin, silicon, hydroxylproline rich glycoproteins, and salicylic acid (Kovats et al 1991;Rasmussen et al 1991;Stein et al 1993).…”

Susceptible and resistant cultivars of cucumber (cv. Suyo and cv. Shogoin fushinari, respectively) were evaluated for induction of systemic resistance by plant growth-promoting fungal isolates Phoma sp. GS8-1 and nonsporulating fungus GU21-2 against Colletotrichum orbiculare. Reduction in anthracnose disease was assessed at regular intervals of 0, 3, 6, and 9 days after challenge inoculation. Activities of endochitinase, β-1, 3-endoglucanase, peroxidase (PO), polyphenol oxidase, and phenylalanine ammonia lyase (PAL) were assayed at the above intervals, while the activities of exochitinase and β-1,3-exogluconase were assayed at 9 days after challenge inoculation. The data showed that all the enzymes activities increased in plants treated with plant growth-promoting fungi (PGPF) compared with nontreated plants of both cultivars. The activities of endochitinase and β-1,3-endoglucanase were highly increased in PGPF-induced plants than in nontreated plants of both cultivars at different time points. Activities of PO, polyphenol oxidase, and PAL also increased between 3 and 6 days due to inoculation with PGPF and decreased thereafter. The activity of PAL at 9 days in PGPF-induced plants was at the same level as that of nontreated plants of both cultivars. Results of this investigation suggest that PGPF-induced systemic resistance is associated with not only high increases in the activities of chitinase and β-1,3-gluconases but also other plant defense-related enzymes such as PO, PPO, and PAL. Roles of other mechanisms rather than accumulation of defense-related enzymes in PGPF-mediated induced resistance in susceptible cultivars were demonstrated.

“…tritici (Hyakumachi 1994;Shivanna et al 1996a). ZR fungal isolates induced systemic resistance in cucumber against several diseases (Koike et al 2001;Chandanie et al 2005Chandanie et al , 2006Saldajeno & Hyakumachi 2011;Elsharkawy et al 2012b). Competition for nutrients or infection sites or induction of resistance might be possible mechanisms of suppression of rice diseases by ZR isolates in the nursery.…”

“…Several studies showed the beneficial effect of rhizosphere bacteria and fungi on plant growth promotion and disease suppression (Baker 1991;Chanway & Nelson 1991;Wei et al 1991;Kleifeld & Chet 1992;Elsharkawy et al 2012aElsharkawy et al , 2012bElsharkawy et al , 2013Sudisha et al 2013). It has been reported that fungal isolates from rhizosphere of cultivated and non-cultivated crops promoted growth of cucumber (Cucumis sativus L.), radish (Raphanus sativus L.), tomato (Lycopersicon esculentum Mill.)…”

Some rhizosphere fungal isolates belonging to Phoma, Penicillium, Trichoderma and Fusarium were evaluated to control Fusarium and Rhizopus blights and bakanae diseases of rice seedlings. Among the isolates, Phoma spp. GS8-2, GS6-4 and GS10-2 showed 74-89% reduction of severity of Fusarium blight in rice seedlings. In case of Rhizopus blight, Phoma spp. GS8-2, GS6-4 and GS12-2 and Trichoderma harzianum GT3-2 reduced disease severity to 81-93%. Phoma sp. GS12-2 was the most effective isolate in controlling bakanae disease (90% reduction in disease severity). The effect of the tested isolates on the growth of rice seedlings varied significantly in terms of fresh and dry weight in rice trays. However, Phoma sp. GS12-2 effectively increased fresh and dry weight of shoots to 40 and 30%, respectively, compared with untreated control plants. In contrast, Phoma sp. GS6-4, T. harzianum GT3-2 and Penicillium sp. GP17-1 showed inhibitory effect to shoot growth of rice seedlings.

Sodium silicate was dissolved in water in either a monomer form or polymer form; the effects of both forms of sodium silicate aqueous solution on rose powdery mildew and root rot diseases of miniature rose were examined. Both forms of sodium silicate aqueous solution were applied to the roots of the miniature rose. Potassium silicate aqueous solution was used as a control and was compared to the effect of sodium silicate aqueous solution. The polymer sodium silicate aqueous solution was the most effective treatment against both powdery mildew and root rot diseases. Moreover, no inhibition effects of silicate solutions were observed in vitro on Pythium helicoides, the causal pathogen of rose root rot disease. The silicon contents in the roots of the miniature rose treated with polymer sodium silicate were significantly greater than that in plants treated with monomer sodium silicate. In conclusion, the suppressive effects of sodium silicate in the polymer form were confirmed against powdery mildew and root rot diseases of the miniature rose.
