南方水稻黑条矮缩病毒(SRBSDV)是最近出现的一种水稻病毒,已经蔓延整个亚洲。这种毁灭性的病毒引起水稻植株在不同生长阶段,产生各种症状。microRNA(miRNA),一群21~24 nt的RNA分子,是植物发育过程和应激反应过程的重要调节剂。SRBSDV感染必然会影响水稻miRNA的表达丰度,然而,尚未有报道说明这种新出现的病毒与宿主miRNA之间的相互作用。华南农业大学的周国辉教授带领的 The southern rice black-streaked dwarf virus (SRBSDV) is a newly emerged rice virus that has spread throughout Asia. This devastating virus causes rice plants to develop various symptoms at different stages of their growth. MicroRNAs (miRNAs), a group of 21-24 nt RNA molecules, are important regulators of plant development and stress response. Infection with SRBSDV will inevitably affect the abundance of rice miRNA expression. However, there is no report about the interaction between this newly emerging virus and the host miRNA.
