[Method] Taking jujube, medlar and soybeam as raw material, the technologies to process compound drinks were studied. The key working procedure was determined. Factors that influenced quali-ty of drinks were studied.[ Result] The best formula was： 30% ：30% ：30% of jujube： medlar： soybean. The color fixative of Vc was 0.02%. The ratio of materials and water was 1 ： 5 mg/ml. The addition of stabilizer xanthan was 0.20%. The addition of white crystal sugar was 6%. [ Conclu-slo] The sensual evaluation of the compound juice of jujube, medlar and soybean was good and the quality achieved national standard.展开更多

It has been shown that Cdcl4 is required for sporulation in the potato blight pathogen Phytophthora infestans; howev- er, the role that the Cdcl4 homolog （PsCdcl4） plays in the soil-borne soybean root rot pathogen P. sojae remains ambiguous. PsCdc14 is highly expressed in spornlation, zoospore, and cyst life stages, but not in vegetative mycelia and infection stages, suggesting that it contributes to asexual reproduction and thus the spread of the disease. Double-stranded RNA （dsRNA） medi- ates gene silencing, a post-transcriptional and highly conserved process in eukaryotes, involving specific gene silencing through degradation of target mRNA. We combined in vitro dsRNA synthesis and a polyethylene glycol-mediated transfor- marion system to construct a dsRNA-mediated transient gene silencing system; and then performed a functional analysis of PsCdcl4 in P. sojae. PsCdc14 mRNA was dramatically reduced in transformants after protoplasts were exposed in in vitro synthesized PsCdc14 dsRNA, resulting in low sporangial production and abnormal development in P. sojae silencing lines. Furthermore, dsRNA-mediated transient gene silencing could enable elucidation of P. sojae rapid gene function, facilitating our understanding of the development and pathogenicity mechanisms of this oomycete fungus.展开更多
