The Genome of Phoebe zhennan (Lauraceae) and Comparative Genomics of Phoebe 楠木(樟科)基因组与楠属植物比较基因组学研究
Phoebe zhennan is a Chinese endemic and valuable timber species of Phoebe (Lauraceae). We present a chromosome‐level genome assembly of P. zhennan. Our research provides novel insights into the genome evolution of Phoebe, including whole‐genome duplication, phylogenetic relationships of magnoliids, and key MYB regulatory genes involved in lignin ...

ABSTRACT Background Chronic cases of canine otitis externa (OE) often develop infections with Pseudomonas aeruginosa (PA). Given the organism's high level of resistance, veterinary surgeons often turn to compounded solutions. Limited data describing the stability and potency of compounded ceftazidime (CAZ) solutions are available, which may affect ...

Summary The importance of marine angiosperms, or seagrasses, as foundation species for marine coastal ecosystems is in marked contrast to their low species number of only 70 described taxa. Seagrass species tend to have very similar overall morphologies dictated by hydrodynamic forces of the ocean environment.

Sox9基因转染诱导L6大鼠成肌细胞向软骨细胞表型分化的研究
利用脂质体转染法,将真核表达质粒pcDNA3.1-Sox9导入L6细胞中.通过细胞增殖检测、细胞形态学观察、标志基因表达分析和甲苯胺蓝染色等方法分析Sox9基因转染对L6细胞增殖和向成软骨方向分化的诱导作用.结果表明,Sox9基因转染对L6细胞的增殖能力没有影响,但能明显抑制L6细胞相互融合形成肌管.和对照相比,Sox9基因转染后,细胞成肌分化标志基因Myf5的表达受到明显抑制,而成软骨分化标志基因Ⅱ型胶原(typeⅡcollagen,Col2a1)和蛋白聚糖(Aggrecan,Agg)的表达显著提高 ...
