| molecular identification and the complete nucleotide sequence of tylcv isolate from shanghai of china. | tomato yellow leaf curl virus (tylcv) belongs to the genus begomovirus, family geminiviridae. it is transmitted by the whitefly bemisia tabaci. a pair of primers was designed according to the specific sequence of the tylcv gene and used in the pcr detection of the virus in the infected tissues of tomato grown in the shanghai area of china. dna was extracted from leaves, fruits, seeds, and roots of infected tomato plants separately. the results showed that the target fragment of about 570 bp coul ... | 2008 | 18373188 |
| [wolbachia extensively harbored by bemisia tabaci in china]. | wolbachia are a group of maternally inherited bacteria harbored by a variety of arthropods and can manipulate the reproductivity of their hosts. eighteen populations of whiteflies were collected from hebei, xinjiang, beijing, shandong, zhejiang, guangxi, hainan, guangzhou and fujian provinces, china. these whiteflies were molecularly identified using internal transcribed spacer 1 its1 rdna sequences. they were then detected for wolbachia infection using wolbachia-specific primers designed based ... | 2008 | 18338578 |
| asymmetric mating interactions drive widespread invasion and displacement in a whitefly. | the role of behavioral mechanisms in animal invasions is poorly understood. we show that asymmetric mating interactions between closely related but previously allopatric genetic groups of the whitefly bemisia tabaci, a haplodiploid species, have been a driving force contributing to widespread invasion and displacement by alien populations. we conducted long-term field surveys, caged population experiments, and detailed behavioral observations in zhejiang, china, and queensland, australia, to inv ... | 2007 | 17991828 |
