ABCG2 and infection: In wheat, Xiao et al. [12] performed a transcriptome comparison of wheat landrace Wangshuibai and a mutant from Wangshuibai (namely, NAUH117) during infection by Fusarium graminearum and suggested that pathogen-related proteins, such as PR5, PR14, and the ABC transporter and JA signaling pathways, were crucial for Fusarium head blight (FHB) resistance, whereas the ethylene (ET) and reactive oxygen species/nitric oxide (ROS/NO) pathways were not activated in Wangshuibai and therefore might not be pivotal in defense against FHB.
