Disease resistance screening protocol against rice (Oryza sativa l.) brown spot (bipolaris oryzae shoem.) and blast (magnaporthe oryzae hebbert barr) diseases using abscissic acid (aba) assay

Abstract

© 2019, International Society for Southeast Asian Agricultural Sciences. All rights reserved. Broad spectrum resistance can combat wide array or strains of a pathogen. Developing broad spectrum resistance requires understanding and screening sources of resistance. Abscissic acid (ABA), a known plant resistance response, was used to differentiate resistance and susceptibility response against brown spot and blast fungal rice diseases in IR64 wild type and mutants. To validate the association of ABA into brown spot and blast resistance, ABA assay was conducted. The study was conducted in International Rice Research Institute in 2013. ABA acid assay was effective in differentiating response of rice against brown spot and blast diseases at 7 days after inoculation (DAI). This study also suggests that IR64 can be used as resistance source against blast and brown spot diseases.
