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

除与RISC结合外，siRNA还引导RITS复合物结合到同源染色质，介导异染色质化过程。

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.

要利用随机碰撞测试方法，对229份自交纯合的甘蓝型油菜品种（系）进行角指数测定，以期筛选出角种质。
