Abstract:

【Objective】The objective of this study is to detect the stem node metabolite of susceptible cultivars which suffered the rice blast under the natural condition, analyze the reason for rice cultivars susceptibility and yield reduction, and to provide a theoretical basis for the susceptible mechanism study of japonica rice and ecological control.【Method】With susceptible cultivar which suffered the rice blast Liaoxing1 and japonica rice restorer C418 as the materials, the yield and quality character including seed setting rate, 1000-grain weight, length, brown rice were measured at the maturation stage. The incidence of panicle neck blast was investigated at the filling stage, and GC-MS was carried out to analyze the metabolites of diseased stem nodes and normal stem nodes, the metabolite composition between diseased stem nodes and normal stem nodes was analyzed by principal components analyses (PCA), the variable weights (VIP>1.0) of partial least-squares discriminant analysis (PLS-DA) were used to screen the species of differential metabolites, the difference of carbohydrate and amino acid metabolites was compared, and the reasons for the decrease of rice yield were analyzed from the metabolites.【Result】The incidence of panicle neck blast of Liaoxing1 and C418 was 57.23% and 82.94%, respectively. The panicle neck blast significantly reduced the head rice rate of the primary branch, the seed set rate, 1000-grain weight, length-width ratio and head rice rate of the secondary branch, there was no significant difference in other characters. 358 metabolites were identified in the two cultivars, the metabolites of diseased stem node increased by 73.46% and 67.88%, respectively. The PCA and PLS-DA analysis could clearly identify the metabolites of diseased stem node and normal stem node. The metabolite phenotypes of Liaoxing 1 and C418 were obviously different between the diseased stem node and normal stem node. Compared with normal stem node, the relative content of 61 metabolites induced by Liaoxing 1 diseased stem nodes changed significantly, and the relative content of 47 metabolites induced by C418 diseased stem nodes changed significantly, there were 30 metabolites in same of the diseased stem nodes of these two cultivars. The relative content of secondary metabolites of vanillic acid, alpha tocopherol, dehydroascorbic acid, triacontanol, daidzein and N-acetyl-d-mannosamine significantly decreased by 87.03%, 96.29%, 77.95%, 74.56%, 86.48% and 82.68% in Liaoxing1, respectively. In C418, it decreased by 99.92%, 99.68%, 97.26%, 86.67%, 94.96% and 76.74%, respectively. The relative content of the above six types of secondary metabolites in normal stem node of Liaoxing1 was 2.64, 2.39, 2.39, 2.27, 3.09 and 2.56 times of that in C418, respectively. The panicle neck blast increased 63.33% of carbohydrate metabolites and 68.42% of amino acid metabolites in stem node, the carbohydrate and amino acid metabolites increased by 1.02-17.92 and 1.05-13.12 times, respectively. Among them, the enhanced amplitude of carbohydrate metabolites in C418 was more significant.【Conclusion】The occurrence of panicle neck blast significantly changed the metabolite composition of susceptible cultivars Liaoxing 1 and C418 stem node, the susceptible cultivar may adjust its defensive reaction to the rice blast following the relative amount change of vanillic acid, alpha tocopherol, dehydroascorbic acid, triacontanol, daidzein and N-acetyl-d-mannosamine. By accumulating a large amount of the carbohydrate and amino acid metabolites, the diseased stem nodes reduce their transport to grains and restrain the formation of yield.
