Comparison of the expressed profiling between bulbs of virus-free and virus-accumulated garlic

To explore the influence of virus-accumulation on garlic growth, we produced a virus-free garlic using the landrace “Chalingzipisuan” with great accumulation of viruses, based on the shoot-tip culture. Then, using the viruses-accumulated garlic and corresponding virus-free garlic, we performed a transcriptomic investigation for the enlarging-growth bulbs, and identified 1,182 garlic genes with differential expression, suggesting these genes involved in the response to viruses-infection The viruses-accumulated garlic was used as the treatment, and virus-free garlic was used as the control. Three biological replicates were performed for each sample. The garlic were infected by four viruses, namely, garlic virus A, D, and X, and garlic latent virus
