Serological assays were used to estimate the proportion of Acalymma vittata (F.) that harbored Erwinia tracheiphila (E. F. Smith) Holland, the causal agent of bacterial wilt in cucurbits. Theseproportionswere related to theproportionofA. vittata that transmitteddisease in singlebeetle caged bioassays. The serological assays classiÞed beetles as harboring the bacteria when the titer was above '1...

The objective of this paper was to investigate the inhibitory effect of total flavonoids from Pteris multifida Poir on growth of transplanted H22 tumour in mice. H22 tumour-bearing mice model was established; the experimental animals were divide/d into the model group, Pteris multifida Poir total flavonoids high-, low-dose groups, and CTX group. Pteris multifida Poir groups were administered co...

Chloroplasts change their positions in the cell depending on the light conditions. In the dark, chloroplasts in fern prothallia locate along the anticlinal wall (dark position). However, chloroplasts become relocated to the periclinal wall (light position) when the light shines perpendicularly to the prothallia. Red light is effective in inducing this relocation in Adiantum capillus-veneris, an...
