Genome-wide analysis of auxin transport genes identifies the hormone responsive patterns associated with leafy head formation in Chinese cabbage.

Auxin resistant 1/like aux1 (AUX/LAX), pin-formed (PIN) and ATP binding cassette subfamily B (ABCB/MDR/PGP) are three families of auxin transport genes. The development-related functions of the influx and efflux carriers have been well studied and characterized in model plants. However, there is scant information regarding the functions of auxin genes in Chinese cabbage and the responses of exogenous polar auxin transport inhibitors (PATIs).

cDNA-AFLP analysis reveals differential gene expression in incompatible interaction between infected non-heading Chinese cabbage and Hyaloperonospora parasitica.

Non-heading Chinese cabbage (Brassica rapa ssp. chinensis) is one of the main green leafy vegetables in the world, especially in China, with significant economic value. Hyaloperonospora parasitica is a fungal pathogen responsible for causing downy mildew disease in Chinese cabbage, which greatly affects its production.

[Investigation of an outbreak of acute diarrhea caused by Human calicivirus].

Background: To survey a diarrhea outbreak in Guangan city and analyze the cause of the disease.

Methods: The population enrolled in the surveillance came from four different settings and was randomly sampled. Stool specimens collected from diarrhea patients were tested ordinarily for enteric bacteria and further examined for viral pathogens with PAGE, ELISA and RT-PCR.
