Overexpression of GmAKT2 potassium channel enhances resistance to soybean mosaic virus.

ABSTRACT:

Background

Soybean mosaic virus (SMV) is the most prevalent viral disease in many soybean production areas. Due to a large number of SMV resistant loci and alleles, SMV strains and the rapid evolution in avirulence/effector genes, traditional breeding for SMV resistance is complex. Genetic engineering is an effective alternative method for improving SMV resistance in soybean. Potassium (K+) is the most abundant inorganic solute in plant cells, and is involved in plant responses to abiotic and biotic stresses. Studies have shown that altering the level of K+ status can reduce the spread of the viral diseases. Thus K+ transporters are putative candidates to target for soybean virus resistance.

Results

The addition of K+ fertilizer significantly reduced SMV incidence. Analysis
