The soybean cyst nematode, Heterodera glycines, adversely affects the production of soybean, Glycine max, in many areas of the world, particularly in the United States, where it is the most economically important soybean pathogen. Despite the availability of hundreds of H. glycines-resistant soybean cultivars, the nematode continues to be a major limiting factor in soybean production. The use of nonhost rotation and resistance are the primary means of reducing losses caused by the nematode, but each of these options has disadvantages. As a subject for study of nematode parasitism and virulence, H. glycines provides a useful model despite its obligately parasitic nature. Its obligately sexual reproduction and ready adaptation to resistant cultivars, formerly referred to as "race shift," presents an excellent opportunity for the study of virulence in nematodes. Recent advances in H. glycines genomics have helped identify putative nematode parasitism genes, which, in turn, will aid in the understanding of nematode pathogenicity and virulence and may provide new targets for engineering nematode resistance.

来自动物界的一种典型植物病原体：异型藻甘氨酸，大豆孢囊线虫。

在世界许多地区，特别是在美国，大豆是最经济重要的大豆病原体，大豆孢囊线虫异形藻甘氨酸对大豆的生产产生不利影响。尽管有数百种抗甘氨酸的大豆品种可用，但线虫仍然是大豆生产中的主要限制因素。使用非宿主旋转和阻力是减少由线虫引起的损失的主要方法，但是这些选择中的每一个都有缺点。作为研究线虫寄生性和毒力的主题，尽管甘草嗜酸菌具有专性的寄生性质，它仍提供了有用的模型。它专心地进行性繁殖，并易于适应抗性品种，以前称为“变种”，为研究线虫的毒力提供了极好的机会。甘氨酸糖原体基因组学的最新进展已帮助鉴定推定的线虫寄生基因，从而有助于了解线虫的致病性和毒力，并可能为工程性线虫抗性提供新的靶点。
