GmSN1 Overexpression Enhances Virus Resistance in Arabidopsis and SoybeanAugust 23, 2017
Soybean mosaic virus (SMV) infection causes massive yield loss in soybean (Glycine max). Scientists led by Hongli He of Northeast Normal University in China compared the gene expressions in an SMV-resistant soybean and a susceptible cultivar. The team found that a subgroup of Gibberellic Acid Stimulated Transcript (GAST) genes were downregulated in the SMV susceptible plants, but not the resistant plants.
Analysis revealed that one of the GAST genes, GmSN1, was closely related to Snakin-1, a potato microbial disease resistance gene. When overexpressed in Arabidopsis and soybean, GmSN1 enhanced turnip mosaic virus resistance in Arabidopsis plants, and SMV resistance in soybean. Further analysis revealed that the expression of GmAKT2, a gene known to enhance soybean-SMV resistance when overexpressed, was elevated in the transgenic soybean.
This study suggests that GmSN1 is capable of enhancing virus resistance in plants by affecting the expression of immune response genes.
