The silique shattering resistance index (SSRI) of 229 accessions (Brassica napus L.) was investigated through random impact test (RIT) for screening silique shattering (SS) resistance.

摘用随机碰撞测试方法，对229份自交纯的甘蓝型油菜品种（系）进行了裂角指数测定，以期筛选出裂角种质。

Another role of siRNA is directing RITS complex to bind with homologue chromosome, and then induces heterochromatinization.

除了与RISC外，siRNA还引导了RITS复到同源染色质，介导异染色质化过程。
