We subsequently evaluated the expression profiles of the three AcJAZ2-like genes and found that only AcJAZ2L2 was differentially regulated between HT and HY at early infection stages (12 and 24 HPI), which were consistent with the CCNA results, suggesting that AcJAZ2L2 may serve a critical role in kiwifruit resistance to Psa (Fig. 2D). This evidence concerns the gene CCNA2 and infection.
