Oilseed plants are a group of plants which are characterized by their rich oil in seeds with distinct biological metabolism pathways of storage matters when compared with starch-rich plants.As oil and its fatty acids provide a group of nutrient substances for human beings and can be used as biodiesel under the background of fossil energy crisis and environmental pollution,this group of plants has been becoming more important in the world economy.

植物抗旱性研究是比较老的研究课题,但是,植物受到水分胁迫时会引起一系列的生理生化变化和形态结构的改变,涉及到许多基因的调控,所以,植物抗旱性是一个相当复杂的问题.玉米是旱地作物中需水量最大,对水分胁迫很敏感的作物之一,在其生育期内至少需要2500mm的降水量.在以往的玉米抗旱研究中,人们都是通过干旱处理或高渗培养液模拟干旱条件,很多研究结果都不太一致,这可能是不同研究者干旱处理或高渗培养液模拟干旱
芒果炭疽病是芒果的主要病害之一,在全世界各芒果产区均普遍发生.该病可造成芒果植株梢枯、叶枯、落花落果及采后果实大量腐烂.芒果炭疽病的病原菌为炭疽菌属Colletotrichum spp.,我国芒果上的炭疽病菌主要为胶孢炭疽菌Colletotrichum gloesporioidesPenz.,该病菌在柑橘、葡萄、芒果上的致病力存在明显差异.广西是我国芒果主产区之一,炭疽病常年流行为害.为弄清广西芒
小麦条锈病是由条锈菌(Puccinia striiformis f.sp.Tritici)引起的世界范围内小麦重要病害之一,培育和种植抗病品种是控制该病害的最有效措施.针对来自国内外的52 份冬小麦种质资源,对其进行中国当前小麦条锈菌流行小种的抗条锈性评价,为中国小麦抗条锈病育种提供依据和抗源亲本.本研究应用中国流行小麦条锈菌生理小种CYR29、CYR31、CYR32、CYR33 以及致病类型V2
条锈病是危害我国小麦生产的最主要的病害之一，创制、筛选新抗源，培育、利用抗病品种是条锈病持久控制的最基本措施。航天诱变技术为小麦改良提供了丰富的可供选择利用的遗传变异。法国面包小麦品种Blue sky 经过卫星搭载，其后代中发现在农艺性状、抗病和抗旱等性状产生广泛变异。为了从中筛选有益的抗病突变体材料，本研究对188 个Blue sky航天诱变的M5代和M6代衍生系，在温室进行苗期分小种(CYR3
利用植原体16S rRNA基因的通用引物R16mF2/R16mR1和R16F2n/R16R2对新疆轮台发生的杏(Prunusyabulakejianali)褪绿卷叶病感病植株总DNA进行巢式PCR扩增，得到了约1.2kb的特异性片段，从分子水平证实了杏褪绿卷叶病的病原为植原体.将扩增到的片断测序，并进行一致性和系统进化树分析.结果表明，该分离物属于植原体翠菊黄化组(Candidatus Phyto
