The differential variations in the abundances of the spots were tested with ANOVA test ( = 0.05) for each treatment. for improving this crop . Rice hoja blanca (RHB) disease has been reported in tropical and subtropical American countries that grow rice. Unlike the phytosanitary scenario of rice in Asia, RHBV was the only viral disease in America until 1991 when the rice stripe necrosis computer virus emerged in South America . RHBV is definitely transmitted from the planthopper insect which grows up to an average size of 2.5 mm. requires high temps (about 27 C) and moisture ( 80% RH), and is also a direct rice infestation [6,7]. Epidemics of Pipequaline RHB happen sporadically, but with catastrophic results in terms of rice crop yields . Distribution of RHBV is determined by environmental conditions that favor the reproduction and survival of its vector. A potential planthopper vector requires up to 12 h to acquire the computer virus from an infected rice plant, and a minimum of a week to a month to total the incubation inside the hopper insect . Also, the computer virus could be transmitted inside a transovarial way; it means from your mother to the progeny. The sign in the rice vegetation is the appearance of chlorotic streaks that can coalesce and cause the leaves to turn yellow or white. When young vegetation become infected, they may be stunted, and in severe infections the leaves change necrotic and the vegetation die. Infections that happen before the emergence of the panicle can reduce seed arranged AMPK and grain quality. There is indirect evidence that rice infected by RHBV may be susceptible to additional diseases. The RHBV computer virus was isolated and partially characterized as a member of the Tenuivirus genus by Morales and Niessen . The level of resistance of a genotype to rice hoja blanca computer virus (RHBV) is determined by the percentage of vegetation that become infected. A testing for RHBV relies on a complex biological system that involves vector colonies, the Pipequaline concentration of the computer virus in the vector, and environmental Pipequaline conditions that can impact the feeding behavior of the vector bugs. In recent years, many scientists possess focused on studies of proteins that happen under various conditions inside a proteomic analysis. Proteomic techniques have been used to analyze manifestation patterns of complex mixtures and to explore gene functions in different cells and the manifestation under stress, for which the genetic factors involved are recognized or associated with defense mechanisms in vegetation [9,10]. There is a need in Colombia to increase the number of resistant varieties to various tensions caused by weather change effects or diseases. In that direction, a set of virus-responsive proteins was founded, and a new approach based on conformationally restricted peptide dendrimers was proposed to detect those proteins . In the present study, Fedearroz 2000 and Colombia 1 rice varieties were evaluated. The Colombia 1 variety was used in all commercial crossings with resistance to RHBV, and has been used like a resistant control assessment in the Centro Internacional de Agricultura Tropical (CIAT) until the appearance of Fedearroz 2000 variety. This variety is definitely resistant to diseases and offers higher productivity than additional varieties used in Colombia. The 1st comparative proteomics study between both varieties for evaluating the differential response of rice against the vector and the computer virus is reported with this study. By carrying out two-dimensional electrophoresis (2-DE) and MALDI-TOF/TOF mass spectrometry analysis of rice leaves, a set of vector- and virus-responsive proteins was founded. Virus-infected vegetation showed significant variations in morphology and rate of metabolism, compared to normal vegetation (control group). In another test, we identified some of these low concentrated proteins in leaf components using peptide dendrimers by immunoenzymatic methods with good results. To get these Pipequaline results, a new approach based on design and synthesis of conformationally restricted peptide dendrimers was proposed. Proteomic results provide new insights into the molecular mechanisms of flower response to computer virus infection and comprehensive tools for the analysis of fresh crop varieties. ELISA results are encouraging and show that it is feasible to design and synthesize peptide dendrimers with target sequences conformationally restricted to Pipequaline -helix to be used for biological.
