Abstract:

Expression profiles of the 147 AP2/EREBP gene family members were studied in rice infected with Rice grassy stunt virus (RGSV), Rice transitory yellowing virus (RTYV), Rice gall dwarf virus (RGDV), Rice black-streaked dwarf virus (RBSDV), Rice ragged stunt virus (RRSV), and Rice dwarf virus (RDV). Microarray analysis showed that 80% of the OsAP2/EREBP genes were differentially regulated during virus infection compared with the control. Rice infected with either RGSV or RBSDV showed the highest number of upregulated OsAP2/EREBP genes, while RTYV infected plants had the lowest. These results correlate with the severity of the syndromes induced by the different viruses. Most (60%) of the genes in the RAV subfamily and B5 subgroup were more highly expressed during RDV-O and RDV-S virus infections, while most (53%) of the genes in the A3 subgroup were down-regulated during RGSV infection, suggesting roles in response to virus infection. The number of genes activated during RDV infections was greatest during infection with the S-strain, followed by the D84-strain and the O-strain, with three OsAP2/EREBP genes up-regulated during infection by all three strains. A common set of 12 genes showed higher expression during infection by at least three viruses, of which, Os05g47650 showed up-regulation during infection with five of the six viruses. Putative cis-elements related to strongly up-regulated genes included, which may assist in assigning these important genes to their functional pathways. We also found several duplicate genes that are classified as neo-functional and sub-functional according to their expression patterns among six virus infections.
