Expression of genes involved in diterpene biosynthesis, especially momilactone and gibberellins (GAs), in rice plants (Oryza sativa L.) in response to barnyard grass (Echinochloa crus-galli) stress was examined. The three analyzed class II diterpene synthases had the highest fold change expression. Transcription patterns of genes for two homologs of momilactone synthases, OsMAS and OsMAS2, suggests their distinct roles in response to the presence of barnyard grass.
研究了水稻（Oryza sativa L.）中参与二萜生物合成的基因（特别是 momilactone 和赤霉素（GAs））对稗草（Echinochloa crus-galli）胁迫的表达。分析的三种 II 类二萜合酶的表达倍数变化最高。两种 momilactone 合酶同源物 OsMAS 和 OsMAS2 的基因转录模式表明它们在响应稗草存在时具有不同的作用。
