Fig 7. Expression of rice genes associated with transposon elements, receptor-like kinases, and NBS-LRR proteins in response to RSV infection.

(A) Expression of genes related to transposon elements (TEs). A total of 17,271 TEs were selected based on the rice genome annotation project. Genes were divided into five groups: not expressed (gray); down-regulated with < 2-fold change (green color); down-regulated with > 2-fold change (dark green color); up-regulated with < 2-fold change (orange color); and up-regulated with > 2-fold change (red color). (B) Expression of genes encoding receptor-like kinases. A total of 1,070 receptor-like kinases belonging to 50 families were selected based on a previous study [39]. (C) The number of expressed NBS-LRR genes on each rice chromosome. A total of 405 rice genes that contained an NBS-LRR domain were selected. The bar graph indicates the number of expressed NBS-LRR genes on each chromosome.
