Arabidopsis WRKY8 transcription factor physically interacts with VQ9 protein, a member of VQ protein family, to modulate salinity stress tolerance. In this study, we further revealed that a large number of VQ proteins interact with WRKY8 in the yeast twohybrid system. WRKY8 strongly interacts with VQ5, VQ10, VQ11, VQ16, VQ20, VQ23, VQ29 and VQ32 and slightly interacts with VQ9, VQ12, VQ13, VQ14, VQ17, VQ21, VQ25 and VQ31 in yeast. Expression analysis showed that WRKY8associated genes VQ10, VQ11 and VQ23 are responsive to abscisic acid (ABA), suggesting that they may mediate ABA response in Arabidopsis. Further analysis indicated that the expression of VQ10, VQ11 and VQ23 genes are induced by salt stress, osmotic stress, cold and/or heat stresses. Subcellular localization analysis showed that VQ10 is a nuclear protein and VQ11 localizes in both the nucleus and the cytoplasm. These results suggest that these WRKY8associated proteins VQ10, VQ11 and VQ23 may modulate multiple abiotic stress responses in Arabidopsis.
