Basic domain-leucine zipper (bZIP) transcription factor, one type of conserved gene family, plays an important role in plant development and stress responses. Although 77  MebZIPs  have been genome-wide identified in cassava, their  in vivo  roles remain unknown. In this study, we analyzed the expression pattern and the function of two  MebZIPs  ( MebZIP3  and  MebZIP5 ) in response to pathogen infection. Gene expression analysis indicated that  MebZIP3  and  MebZIP5  were commonly regulated by flg22,  Xanthomonas axonopodis  pv.  manihotis  ( Xam ), salicylic acid (SA), and hydrogen peroxide (H 2 O 2 ). Subcellular localization analysis showed that MebZIP3 and MebZIP5 are specifically located in cell nucleus. Through overexpression in tobacco, we found that  MebZIP3  and  MebZIP5  conferred improved disease resistance against cassava bacterial blight, with more callose depositions. On the contrary,  MebZIP3-  and  MebZIP5 -silenced plants by virus-induced gene silencing (VIGS) showed disease sensitive phenotype, lower transcript levels of defense-related genes and less callose depositions. Taken together, this study highlights the positive role of  MebZIP3  and  MebZIP5  in disease resistance against cassava bacterial blight for further utilization in genetic improvement of cassava disease resistance.
