1橘蚜传播柑橘衰退病毒的研究进展显示文摘就橘蚜传播柑橘衰退病毒 (CTV)的传毒特性、传毒率、影响传毒率因素、与柑橘衰退病流行的关系、对混合株系的虫传分离作用以及带毒橘蚜的分子生物学检测等研究进展作一综述 .橘蚜传播 CTV的方式为非循回型半持久式 ,其从甜橙和墨西哥莱檬植株上传播 CTV的效率高于棉蚜、橘二叉蚜和绣线菊蚜等蚜虫 .橘蚜对 CTV不同株系的传毒率有所差异 ,对重型株系的传毒率较轻型株系高 .影响传毒率的因素有蚜虫发育虫态、毒源植物、接毒植物和环境条件等 .橘蚜与酸橙砧甜橙衰退病的发生与流行 ,特别是衰退型强株系衰退病的发生与流行有密切相关性 ,它是甜橙衰退病发生与流行的最主要传播介体 .橘蚜对 CTV具有分离株系的作用 ,通过单虫传播 ,可以将混合感染状态的 CTV不同株系分离而获得纯化株系 .检测橘蚜携带 CTV的分子生物学反转录 -聚合酶链式反应技术已建立 ,并已应用于检测橘蚜等蚜虫的单虫带毒情况 .讨论认为 ,不同发育虫态、毒源植物、接毒植物和环境条件等因素对橘蚜传播 CTV的影响 ,特别是毒源植物和温度条件对橘蚜传毒率的影响 ,及利用橘蚜单虫传播分离林尤剑 谢联辉 POWELL C A 2001福建农业大学学报2001,30,1:13
2Leukemia:研究鉴定出与34种AML白血病亚群相关联的基因突变显示文摘针对成年急性髓细胞白血病(acute myeloid leukemia,AML)患者的一项新的大型研究将80种癌症相关基因突变与5种AML亚型相关联。这5种AML亚型可通过特异性的染色体异常加以确定。在未来,这些发现可能有助指导基因突变测试和治疗决策。A-K Eisfeld K Mrózek J Kohlschmidt D Nicolet S Orwick C J Walker K W Kroll J S Blachly A J Carroll J E Kolitz B L Powell E S Wang R M Stone A de la Chapelle J C Byrd C D Bloomfield 2017现代生物医学进展2017,17,15:7
