“…Presence of higher concentration of proteins was associated with the action of induced resistance because the elicitors are responsible for triggering a signal in the host when occur the attack of a pathogen. These results were also in par with other authors (Hwang and Kim, 1990;Du and Wang, 1992;Anuratha et al, 1996;Benhamou, 1996;Manandhar et al, 1999;Kuc, 2001;Kombrink and Schmelzer, 2001) (Table 2, 3).

In barley plants , the disease detected as spot blotch is caused by Bipolaris sorokiniana, and is the most deleterious disease for the producers and the beer industry. For fungicides mediated control of this disease can cause risks to environment and human health. To eliminate these drawbacks, one of the methods considered is the use natural products. The purpose of the present study was to investigate the use of extract of leaves from Bauhinia variegata Link. and Opera ® fungicide (active ingredient: pyraclostrobin) for controlling Bipolaris sorokiniana in barley plants. In Brazil there are two species of Bauhinia are seen, namely Bauhinia forficata and B. variegate. Extracts from B. variegata didn't show fungitoxic action but B. forficata the action exist. The barley plant showed protection of 92 to 100% in local and systemic action. The chemical TLC assays showed the presence of phenols (rutin, coumaric acid, kaempferol) that can be related to a signal for activation of the defense responses against pathogen or mechanism of salicylic acid. Treatment with fungicide Opera ® gave another mechanism and have only 60% of protection.

“…This enzyme is called a PRprotein, and has been considered one of the main factors involved in the mechanism of resistance induction in plants, as reported by Manandhar et al [15], Reiss and Bryngelsson [17] and Liljeroth et al [13].…”

“…Some genes are responsible for the expression of resistance, and may express great activity of both hydrolytic and anti-oxidant enzymes, or even express other macromolecules [15,20]. In barley, analysis and quantification of b-1,3 glucanase is an important factor, due to its accumulation in resistant plants.…”

“…This may be achieved by the use of elicitors, substances that induce defense reactions in plants, including the production of phytoalexins, proteins related to pathogenesis, such as PRproteins (chitinases or b-1,3 glucanases) or even protease inhibitors [3,10,11,16]. Thus, resistance induction has been observed and suggested as an alternative control method in different pathosystems, such as wheat-Bipolaris sorokiniana and Drechslera teres [1]; coffee-Hemileia vastatrix [7]; ricePyricularia oryzae and Bipolaris sorokiniana [15] and pepper-Phytophthora capsici [8].…”

“…oryzae, causing bacterial leaf blight disease (Hilaire et al 2001). Genes for peroxidases were also induced by infection with the rice blast fungus Magnaporthe grisea (Manandhar et al 1999;Schweizer et al 1997). Furthermore, the increased activity of ß-1,3-glucanase (PR-2) and upregulation of the corresponding gene have been observed in R. solani-infected and also in Sclerotium oryzae-infected rice plants (Simmons et al 1992;Anarutha et al 1996).…”

Sheath blight, caused by anastomosis group 1-IA of Rhizoctonia solani Kühn (teleomorph Thanatephorus cucumeris (Frank) Donk), is one of the most destructive rice diseases worldwide. The pathogen is able to infect plants belonging to more than 27 families, including many economically important monocots and dicots such as rice, wheat, alfalfa, bean, peanut, soybean, cucumber, papaya, corn, potato, tomato and sugar beet. It is a soil borne necrotrophic fungus that survives in plant debris as sclerotia, which are small brown-to-black, rocklike reproductive structures. The sclerotia can survive in the soil for several years and infect rice plants at the water-plant interface in the flooded field by producing mycelia. Management of rice sheath blight requires an integrated approach based on the knowledge of each stage of the disease and cytomolecular aspects of rice defence responses against R. solani. This review summarizes current knowledge on molecular aspects of R. solani pathogenicity, genetic structure of the pathogen populations, and the rice-R. solani interaction with emphasis on cellular and molecular defence components such as signal transduction pathways, various plant hormones, host defence genes and production of defence-related proteins involved in basal and induced resistance in rice against sheath blight disease.
