Figure 3 |. The circadian regulator, CCA1, controls the defence gene expression and the timing of immune responses.
a, Enrichment of evening element (EE) (P<10−5). NMF, non-negative matrix factorization; CCA1, CCA1-binding sites; Circadian correl., circadian correlations14. +, sense; −, antisense. b, SPP count 7 dpiby Hpa Emwa1 (n=3). c, Time-course expression of NMF Cluster 1 genes. CI, confidence interval; CK, control; EMWA1, Hpa Emwa1 inoculated. White bars, day; black bars, night. d, SPP count after Hpa Emwa1 infection at dawn or dusk (n=3). e, Occurrence of DIH 7 dpi by Hpa Emwa. f, A model showing circadian regulation of the defence genes in anticipation of infection under normal conditions, in basal and R-gene-mediated resistance. The blocked arrows represent defence against infection.
