“…It has been recently reported, that PR-3 transcripts increase in rice plants inoculated with R. solani after treatment with leaf extracts of Zizyphus jujuba Mill. overexpression (Kagale et al 2011). The antifungal activity of PR-3 product in in vitro studies on Fusarium solani and R. solani has also been proven (Broglie et al 1991;Sela-Buurlage et al 1993).…”

Pathogenesis related (PR) genes of rice are among the most important defense genes in the interaction of rice with pathogens. In this study, the role of NH-1, several PR genes, phenylalanine ammonia-lyase (PAL), and lipoxygenase in the defense responses of rice against Rhizoctonia solani, the causal agent of rice sheath blight disease, was evaluated. The Tarom and Khazar cultivars (cvs), as resistant and susceptible genotypes, respectively, were used. The expression rate of defense genes in two-week-old seedlings inoculated with a virulent isolate of R. solani AG-I-1 A was investigated. The lesions in the Tarom cv were less than half the size of those on the Khazar cv. The expression scripts of the genes were calculated by quantative Real-Time PCR (RT-PCR). Results showed that the expression rate of all genes in the resistant cultivar was higher than that of the susceptible genotype, post inoculation. Analysis of data by the t-Student test also indicated significant differences in the expression level of the genes between Khazar and Tarom.The results of this study suggest that the investigated genes are involved in the resistance responses of rice against the sheath blight agent. For the first time, the induction of PR-5, PR-9, PR-10, PR-12, PR-13, and NH-1 was observed in this study in the resistant and susceptible Iranian cultivars of rice following attacks by R. solani.

“…Sheath blight (SB), caused by the soilborne fungus Rhizoctonia solani, is one of the most destructive rice diseases worldwide, resulting in severe loss of yield and quality in rice production (Tan et al, 2007). Moreover, its damage has become more serious as a result of the widespread use of semi-dwarf, nitrogen-responsive and high-yielding varieties (Kagale et al, 2011). Although chemical control is an effective method to cope with SB, it is unsustainable because of high cost and serious environmental pollution.…”

Sheath blight (SB) is one of the most destructive rice diseases that affect the yield and quality of rice. Jasmonate and Ethylene Response Factor 1, designated JERF1, can be induced by ethylene, methyl jasmonate (MeJA), abscisic acid (ABA) and salt stress. Previous research demonstrated that over-expression of JERF1 enhanced drought tolerance by regulating the expression of stress-related genes in rice. The present study reports that JERF1 could improve SB resistance of transgenic rice. At the molecular and physiological levels, JERF1 could up-regulate the expression of signalling and defence-related genes and increase the activities of lipoxygenase (LOX) and phenylalanine ammonia lyase (PAL). Analysis of cis-elements showed that there were several DRE/CRT (dehydration-responsive element/C-repeat) and/or GCC boxes in the promoters of these candidate genes, indicating that JERF1 might regulate the expression of defencerelated genes via interaction with these cis-elements. These results suggest that JERF1 might improve SB resistance by modulating the expression of defence-related genes. This may prove to be a useful strategy for genetic engineering to improve SB resistance using transcription factor genes in rice.

Ipomoea carnea commonly known as Besharam or Behaya tree belongs to the Convolvulaceae family. Plant is the native of America. Because of fast growing nature of Ipomoea carnea, it is widely distributed in India. If the pregnant animal (Got) eat this plant it was found that a lack of maternal infants bonding. Due to this nature, generally the plant called as Besharam / Behaya or Shameless. In this article we emphasize on control the uncontrolled propagation of Ipomoea carnea, and utilize as biogas with cow dunk cake, different Species of Ipomoea available in different part of India, phytoconstituent of Ipomoea carnea, responsible for his toxic nature like Swainsonine, and pharmacological, toxicological property of Ipomoea carnea , like anti-bacterial, anti-fungal, anti-oxidant, anti-cancer, etc.
