– The difference of expression pattern in defense pathways regulated by Phenylalanine ammonia-lyase genes (PAL) among SHWs and their tetraploid and diploid parents. (A) Expression of genes involved in L-phenylalanine catabolic process (GO:0006559), response to salicylic acid (GO:0009751) and lignin biosynthesis (GO:0009809) in two SHWs and their tetraploid and diploid parents following FCR infection. (B) Scatter plots of fold changes for PAL genes. n represents number of genes. (C) The difference of expression pattern in lignin and salicylic acid biosynthesis pathways between SHWs and their tetraploid parents. C4H, cinnamic acid 4-hydroxylase; C3H, coumarate 3-hydroxylase; 4CL, 4-coumarate coenzyme A ligase; CCoAOMT, caffeoyl CoA O-methyltransferase; CCoA3H: p-coumarate3-hydroxylase; CCR, cinnamoyl-CoA reductase; F5H, ferulate 5-hydroxylase; COMT, caffeic acid O-methyltransferase; CAD, cinnamyl alcohol dehydrogenase; AIM1, abnormal inflorescence meristem 1;BA2H, benzoic acid 2-hydroxylase
