Compared with WT, the result showed that the expression of ATG1 increased at 3 h and then no longer changed in npr1 with AvrRpt2 treated for 9 h; the expression of ATG6 in npr1 increased at 3 h, decreased rapidly at 6 h, then gradually increased again at 9 h; the expression of ATG8a gradually increased until 6 h, then decreased at 9 h in npr1. In summary, these results suggested that NPR1 inhibits the mRNA expression of ATG1, ATG6 and ATG8a during AvrRpt2 infections. This evidence concerns the gene ULK1 and infection.
