科学家发现微RNA,而不是蛋白质基因 控制蝴蝶和飞蛾中的暗翼颜色 Scientists find a microRNA, not a protein gene, controls dark wing colors in butterflies and moths.

科学家发现一个叫做MIR-193的微RNA, 而不是蛋白质编码基因“皮层”, 是蝴蝶和飞蛾花翼颜色的主要调节者。 Scientists have discovered that a microRNA called miR-193, not the protein-coding gene 'cortex', is the key regulator of melanic wing coloration in butterflies and moths. 在《科学》中发表的这一发现表明,干扰MIR-193消除了不同蝴蝶物种的黑色和黑色。 This finding, published in Science, shows that disrupting miR-193 eliminates black and dark wing colors across different butterfly species. 这一发现突出表明了非编码的RNA在控制胎儿特征方面的重要性,并表明MIR-193在整个动物王国中可以发挥节制的作用。 The discovery highlights the importance of non-coding RNAs in controlling phenotypic traits and suggests a conserved role for miR-193 across the animal kingdom.
