水稻白色尖线虫（RWTN）和菊花叶线虫（CFN）是侵染植物地上部分的迁飞性植物寄生线虫。本研究在室内无菌培养条件下，用RWTN和CFN侵染拟南芥，线虫在叶片中引起可识别的症状。此外，RWTN和CFN完成了它们的生命周期并增殖。因此，A.结果表明，拟南芥是RWTN和CFN的新寄主。RWTN和CFN的最适接种浓度为100条/株，最适接种时间分别为21和24 d。不同RWTN种群的致病力和繁殖率不同。拟南芥Col-0生态型与此呈显著正相关。最佳A.对RWTN和CFN最敏感的生态型分别为Col-0和WS。此外，RWTN是外寄生的，CFN是外寄生和内寄生的。thaliana.接种后叶片中的RWTN和CFN向整株迁移，接种后植株不同部位的线虫数量也有不同程度的增加。与距离接种点的距离无关。本文详细地研究了叶线虫在苹果树上的行为和侵染过程。thaliana.
The rice white tip nematode (RWTN), Aphelenchoides besseyi and the chrysanthemum foliar nematode (CFN), Aphelenchoides ritzemabosi are migratory plant parasitic nematodes that infect the aboveground parts of plants. In this research, Arabidopsis thaliana was infected by RWTN and CFN under indoor aseptic cultivation, and the nematodes caused recognizable symptoms in the leaves. Furthermore, RWTN and CFN completed their life cycles and proliferated. Therefore, A. thaliana was identified as a new host of RWTN and CFN. The optimum inoculum concentration for RWTN and CFN was 100 nematodes/plantlet, and the optimum inoculum times were 21 and 24 days, respectively. For different RWTN populations, the pathogenicity and reproduction rates were different in the A. thaliana Col-0 ecotype and were positively correlated. The optimum A. thaliana ecotypes were Col-0 and WS, which were the most susceptible to RWTN and CFN, respectively. Additionally, RWTN was ectoparasitic and CFN was ecto- and endoparasitic in A. thaliana. The RWTN and CFN migrated from inoculated leaves to the entire plantlet, and the number of nematodes in different parts of A. thaliana was not correlated with distance from the inoculum point. This is a detailed study of the behavior and infection process of foliar nematodes on A. thaliana.
