摘 要：Virus-induced flowering（VIF） assays exploit RNA or DNA viruses to express flowering time genes such as Flowering Locus T（FT） to induce flowering in plants1,2. Such plant virus-based techniques have recently attracted widespread attention for their fundamental and applied uses in flowering physiology and in accelerating breeding in dicot crops and woody fruit-trees. However, the insight into VIF, its potential as a powerful tool for dissecting florigenic proteins as well as its establishment in monocot crops remained to be elucidated. During my presentation, I will briefly explain different forms of virus-based technology for plant functional genomics, then move onto describing the mechanism and further applications of VIF in the short-day Nicotiana tabacum cultivar Maryland Mammoth, a dicot plant3. I will also present our latest work onextending this technology for the first time to proso millet, a monocot grass and wheat, a cereal crop4. These will lead to conclude that VIF represents a simple and efficient system to identify individual amino acids that are essential for FT-mediated floral induction and to test the ability of mono-and dicotyledonous FT genes and FT fusion proteins to induce flowering. VIF is also applicable to many economically important monocotyledonous food and biofuel crops.
