Agar was first introduced into the laboratory in 1881. Since then, microbiologists have depended on agar to create strong jellies. When microorganisms are streaked or plated onto this jellied surface and incubated, individual cells multiply into distinct colonies that scientists can easily observe, select, and propagate for further experiments. Many of the most important findings in biological research of the last 150 years or so — including the discovery of the CRISPR/Cas9 gene-editing tool — have been enabled by agar.4 Agarose, a derivative of agar, is also essential in molecular biology techniques like gel electrophoresis, where its porous gel matrix separates DNA fragments by size, enabling researchers to analyze and isolate specific genetic sequences.,详情可参考51吃瓜

其实,蜡梅和梅花既没有亲缘关系,也不是同一个品种。蜡梅是蜡梅科蜡梅属,梅花则是蔷薇科李属。从花期上看,蜡梅比梅花开得更早,开花的时候一般树上还有宿存的褐色果子。
