In the 1990s a sugarcane disease called Yellow Leaf Syndrome was recorded in plantations worldwide. A viral (Sugarcane Yellow Leaf Virus) and a bacterial pathogen (Sugarcane Phytoplasma) were proposed as pathogens. In the meantime the virus was identified as a causal agent and much work concentrated on the virus. However, the relationship between symptoms and viral presence is not strict. One report claims that phytoplasma may enhance the symptom development. Our preliminary work now identified 2 phytoplasma strains in Hawaiian cultivars, which were also infected by the virus. The project intends- to further characterize these phytoplasma strains,- to test which treatment eliminates phytoplasma,- to evaluate how much plantation plants are infected by phytoplasma,- to determine phytoplasma titer in symptomatic versus non-symptomatic plants,- and to determine whether the probable insect vectors of phytoplasma, which are found in the plantations, are infected by phytoplasma.

在20世纪90年代，一种名为黄叶综合症的甘蔗疾病在世界各地的种植园中被记录在案。病毒（甘蔗黄叶病毒）和细菌病原体（甘蔗植原体）被认为是病原体。在此期间，该病毒被确定为致病因子，许多工作集中在该病毒上。然而，症状和病毒存在之间的关系并不严格。一份报告声称植原体可能会加剧症状的发展。我们的初步工作现在在夏威夷栽培品种中鉴定了2个植原体株系，它们也被病毒感染。该项目旨在-进一步描述这些植原体菌株的特征，-测试哪种治疗方法可以消除植原体，-评估植原体感染的种植植物数量，-确定有症状与无症状植物中的植原体滴度，-并确定种植园中发现的植原体可能的昆虫媒介是否被植原体感染。
