昆虫学昆虫学是一门学科.
生态生态学生态生态学

背景情况:

植物性质是由叶传播的植物病原体,对它们的宿主协会的了解不完全.
了解植物质-载体-植物相互作用对于疾病管理至关重要,特别是在自然生态系统中.

研究的目的:

为了研究植物质感染的叶的植物养范围.
分析叶跳载体,它们的宿主植物和植物质之间的共生关系.
为了确定患上植物等离子体疾病爆发风险的地区.

主要方法:

固定混合丰富 (AHE) 被用于从五种植物基因 (rbcL,matK,ITS1,ITS2,trnH-psbA) 中恢复DNA.
从全球58只以前感染了植物质体的叶跳鸟中提取了DNA.
用BLAST和植物遗传学分析来识别植物分类,并评估昆虫与植物的关联.

主要成果:

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...
