Identification of rice genes differentially expressed upon virulent infection by Magnaporthe grisea

Two-week old rice plants (cultivar Nipponbare) were treated with either Magnaporthe grisea (virulent isolate FR13) spore suspension in gelatine or gelatine alone. Two time points were taken (3 and 4 days post inoculation- dpi). Disease symptoms were not visible at 3 dpi whereas they were at 4 dpi. Two biological repeats were done.

两周苗龄的水稻植株（品种为日本晴（Nipponbare））分别接受两种处理：其一为施加含有强毒分离株FR13的稻瘟病菌（Magnaporthe grisea）孢子明胶悬浮液，其二为仅使用明胶进行处理。实验设置两个取样时间点：接种后3天与4天（days post inoculation，简称dpi）。接种后3天时未观察到任何病害症状，而接种后4天时可见典型病害症状。本实验共完成两次生物学重复。关键词：正常组与病害组对比、时间进程分析、处理组与未处理组对比；水稻样本共8张芯片（arrays）
