The sequence of a sat-RNA of cucumber mosaic virus (CMV-Rs) originally isolated from Raphanus sativus in Hangzhou, Zhejiang Province in April 1998, was determined. This satllite was found consisting of 368 nucleotides (nt). Compared its nucleotide sequence with those of 12 CMV sat-RNAs in document,...

This study was to evaluate the effects of Tunip mosaic virus (TuMV) infection on the photosynthetic characteristics of Chinese cabbage (Brassica chinensis L. cv. Suzhou) and mustard (B. juncea L. cv. Wenzhou). As the result of infection, the chlorophyll content, net photosynthetic rate (Pn), stomata...

A filamentous virus was isolated from naturally infected squash (Cucuribita moschata L.), showing yellow mosaic in Hangzhou, Zhejiang Province, in autumn 1999. This virus was found to cause systemic symptoms on all the Cucuribitaceae plants tested. It was identified as zucchini yellow mosaic virus (...

The effects of epibrassinolide on ultrastructure of epidermous cell in hypocotyl segments of mung bean seedlings were studied. Hypocotyl segments treated with epibrassinolide (1 mg/L) maintained the integrity of ultrastructure of cell, and retarded the senescence, whereas the various organelles of t...

Chicken interleukin-2 (chIL-2) is an important cytokine discovered recently. To explore a new approach to the expression of chIL-2 gene in methyltrophic yeast-Pichia methanolica (P. methanolica), the chIL-2 gene was obtained by PCR and inserted into the expression vector pMETαA. The recombinant P. m...
