Summary Treatment of suspension‐cultured cells rice ( Oryza sativa L.) with cell wall extract blast fungus Magnaporthe grisea ) elicits a rapid generation H 2 O , alkalinization culture medium, and eventual death. To elucidate genes involved in these processes, we exploited SAGE (Serial Analysis Gene Expression) technique for the molecular analysis death treated elicitor. Among downregulated elicitor‐treated cells, BI‐1 gene coding Bax inhibitor was identified. Transgenic overexpressing Arabidopsis showed sustainable survival when challenged M. Thus, plant plays functional role regulating system.
