Microbial Organic Compounds (MVCs) as an Inducer of Strawberry Plant Resistance to Strawberry Vein Banding Virus (SVBV) Infection

Abstract

Strawberry vein banding virus (SVBV) is a plant virus that greatly affects the quantity and quality of strawberry plants. An alternative method in controlling SVBV is to increase plant resistance induced by Microbial Organic Compounds (MVCs) produced by the bacterium Bacillus coagulans. The results showed that B. coagulans treatment that produced 28 MVCs was able to reduce disease severity based on symptom development and reduce virus accumulation in strawberry plants based on NAE. Identification of antiviral compounds by GC-MS showed that strawberry leaves inoculated with SVBV in B. coagulans treatment contained antiviral compounds cytosine riboside (1.53%), palmitic acid (15.9%), linolenic acid (41.81%), and 1-naphthalenesulfonic acid (6.46%). The results of this study indicate that B. coagulans is able to induce systemic resistance to SVBV infection in strawberry plants.
