%X In an effort to elucidate the mechanism of redistribution of a 57 Kda protein from chloroplasts to cytoplasmic polysomes when maize seedlings encounterd a stress, maize genotypes resistant  or susceptible to Bipolaris maydis were used for evaluation under inoculated or heat-shocked conditions. Western blot analysis indicated, that the redistributed 57KDa protein caused by a treatment with pathogens or heat shock was identical. When maize seedlings were resistant  to pathogens, little amount of this protein could be detected in the cytoplasmic polysome fraction; cytoplsmic polysomes in response to stresses is not unique to maize. A preliminary study employing a compatible Phytophthora megasperma-soybean interaction system indicated that soybean also respond to pathogenic stress in that the 57KDa protein was detected in the preparation of cytoplasmic polysomes.
