有关中国细齿缺萼苔(Gymnomitrioncrenulatum)和中华缺萼苔(G.sinense)资料

细齿缺萼苔 (G .crenulatumGott.exCarr.)的中国记录为错误鉴定 ,标本实为中华缺萼苔(G .sinenseK .Muell.) ,应被移出中国苔藓植物区系。研究发现了多号西藏产中华缺萼苔标本 ,将中华缺萼苔其在中国的分布范围从云南的模式产地扩展到了西藏。对中华缺萼苔进行了形态特征描述和分布分析 ,并提供了特征示意图

G-quadruplex-based DNAzyme for facile colorimetric detection of thrombin

Thrombin-binding aptamer is found to bind hemin to form a catalytic complex whose activity is significantly promoted by the addition of thrombin, which enables the colorimetric detection of thrombin with high specificity and sensitivity in a facile way.
