Radopholus similis(Cobb 1893) Thorne(1949) is a destructive migratory endoparasitic plant nematode. In this study,the pathogenic process of R. similis infection in Nicotiana benthamiana(tobacco) was studied using quartz sand culture in laboratory. The results showed that R. similis mainly parasitised the root cortex, leading to cortical cell decomposition and tissue decay. We optimised the inoculation conditions to establish a method for determining the pathogenicity of R. similis as follows:(1) a glass culture tube was filled with quartz sand(about 1/3 of the height) and sterilised twice;(2) 20-day-old N. benthamiana seedlings were transplanted into test tubes and cultivated for 10 days at(25±1)°C;(3) R. similis female nematodes were inoculated in the root rhizosphere at a rate of 150 nematodes per plant;(4) the number of nematodes, disease severity, and growth of the plant at 30 days post-inoculation(dpi) were determined. The pathogenicity of eight R. similis populations from different hosts was determined, which proved the feasibility of this method.

Circadian clock genes in peripheral tissues usually play an important role in regulating the circadian rhythms. Light is the most important environmental signal for synchronizing endogenous rhythms with the daily light-dark cycle, and compound eyes are known as the principal circadian photoreceptor for photic entrainment in most moths. However, there is little evidence for circadian timing in compound eyes. In the current study, we isolated the timeless gene, designated Ha-tim (GenBank accession number: KM233162), from the cotton bo 11 worm Helicoverpa armigera. Ha-tim and period (Haper) showed low messenger RNA levels in the compound eyes compared to the other tested adult organs. Ha-tim and Ha-per transcript levels were dependent on an endogenous rhythm that fluctuated over a daily cycle in the compound eyes and heads. The cycles of Hatim and Ha-per transcript levels followed similar time courses, and identical expression patterns of the two genes were observed in the compound eyes and heads. Ha-tim and Ha-per were dowregulated in the compound eyes after light exposure, copulation and starvation. These results indicated that Ha-tim and Ha-per transcript levels were regulated by endogenous and exogenous factors. Our study helped to improve our understanding of the circadian clock machinery in compound eyes and other peripheral tissues.
