Now the improvement of biomass pyrolysis oil(bio-oil)quality mainly focuses on two aspects,namely the selective pyrolysis of biomass and the upgrading of the generated bio-oil.The upgrading of bio-oil is crucial for its final application.An innovative bio-oil graded upgrading way based on molecular distillation is established,to overcome the problems like low conversion efficiency and serious catalyst deactivation during the upgrading of whole bio-oil by a single technique.The distilled fraction(DF)from molecular distillation,which enriches the reactive small molecular acids and ketones,was used for catalytic cracking to produce bio-gasoline; the residual fraction(RF),which contains a lot of sugar and phenol oligomers with low reactivity,was used for emulsion fuel production with diesel.

开花是植物生活周期中的重要时期阶段,是植株实现由营养生长阶段向生殖生长阶段转变的标志,是形成种子和果实的前提。因此,研究水稻抽穗期有利于保证水稻产量。前期本课题组已克隆了一个控制水稻成花转化的关键基因RID1(Rice Indeterminte 1),它编码一个C2/H2类锌指结构的转录因子,其T-DNA插入突变体rid1出现“不开花”的表型。根据RID1基因芯片数据中糖代谢相关基因表达量差异显著
玉米(Zea mays L.)是一种常见的异花授粉作物,但是存在一类玉米(通常是爆裂玉米),可以作为父本与普通玉米杂交,但不能作为母本接受普通玉米的花粉,具备单向杂交不亲和性(Demerec 1929)。同时以普通玉米为母本,爆裂玉米为父本的杂交后代也存在显著的偏分离现象,目前认为由其基因组中的一类配子体因子(Gametophyte factor,Ga)控制(Nelson 1952)。为探究玉米杂
