Fig. 7: NAC36 negatively regulates plant immunity by controlling the NHP and SA biosynthetic pathways.
From: A NAC triad modulates plant immunity by negatively regulating N-hydroxy pipecolic acid biosynthesis
a Co-expression analysis identified potential transcriptional regulators of NHP biosynthesis. Each triangle in the color nightingale rose charts represents a single gene family. b Phenotype of wild-type (WT), nac61 mutants (nac61-1 and nac61-2), and nac36 mutants (nac36-1 and nac36-2). Bar = 1 cm. c Growth of Psm ES4326 on leaves of 4-week-old WT, nac36 mutants. d, e Abundance of NHP (d) and SA (e) in leaves of 4-week-old WT, nac61 mutants (nac61-1 and nac61-2), and nac36 mutants (nac36-1 and nac36-2) upon Psm ES4326 infection. f Transcript levels of PR1 in leaves of 4-week-old WT, nac61 mutants (nac61-1 and nac61-2), and nac36 mutants (nac36-1 and nac36-2) plants upon Psm ES4326 infection. Values showed here were the average of three biological replicates and error bars represent the SDs of three biological replicates (n = 3). Asterisks indicate significant changes compared to WT samples as calculated by Student’s t test (*p value < 0.05; **p value < 0.01; ***p value < 0.001).
