Abstract: Ca2+ ions play an essential role in various plant developmental processes and in plant response to environmental stimuli. Plants have evolved a diversity of unique proteins that bind Ca2+. Calcineurin B-like proteins (CBLs) represent one of the main classes of Ca2+ sensors in plants. There are 10 members of CBLs in rice genome. Here, we used western blot analysis to examine the expression patterns of CBLs in rice leaves at different developmental stages under normal growth conditions. We then investigated the expression of CBLs at different time-points in rice incompatible responses against Xanthomonas oryzae pv. oryzae (Xoo) mediated by bacterial blight-resistant gene Xa21. The expression of OsCBL-1, -3, -5, -9 and -10 changed in incompatible responses. Furthermore, the expression of CBL proteins differed among compatible and incompatible interaction and mock controls, which suggests that CBL proteins may play roles in the interaction between rice and Xoo.
