miR160-ARF18模块开花功能草莓(Fragaria×ananassa Duch.)属于蔷薇科草莓属多年生草本植物,具有较高的经济价值和营养价值.草莓开花的早晚直接关系到草莓的生产环节,间接影响了草莓的经济收益.开花是一个极其复杂的过程,需要多个基因交叉调控,才能精准控制开花时间.本研究通过构建MIR160,ARF18过表达载体和ARF18敲除载体,...
近日,Plant Biotechnology Journal在线发表了南京林业大学完成的题为“The peu-miR160a−PeARF17.1/PeARF17.2 module participates in the adventitious root development of poplar”的研究论文,解析了miR160-ARF17s模块对林木不定根发生的调控机制。 作为林木基础生物学研究的模式树种,杨树茎段不定根发生过程与拟南芥...
Here we show that miR160 and its target genes ARF10, ARF16 and ARF17 modulate hypocotyl elongation in a light, brassinazole (BRZ, a BR biosynthesis inhibitor), or paclobutrazol (PAC, a GA biosynthesis inhibitor)-dependent manner in Arabidopsis. miR160, ARF10, ARF16 and ARF17 have no ...
5′RACE结果显示,Ppe-miR160a以裂解的方式作用于3个ARF靶基因,且裂解位点均位于Ppe-miR160a5′端的第9和第10位碱基之间.IAA响应分析表明,与对照相比,IAA处理后的桃果实中Ppe-miR160a以及3个靶基因3′端裂解产物的表达量均显著升高.以上结果表明桃果实中的Ppe-miR160a通过介导其3个靶基因的裂解参与生长素信号...

Using endogenous target mimic (eTM) analysis, we predicted that lncRNA354 had a potential binding site for miR160b. Transient expression in tobacco demonstrated that lncRNA354 was a miR160b eTM and attenuated miR160b suppression of its target genes including auxin response factors (ARFs). ...
