Distribution of vitamin B-12 in some fishes and marine invertebrates

Distribution of vitamin B-12 in the skeletal muscle of several marine and fresh water fish and marine invertebrates are reported. The vitamin B-12 content of white muscle of various fish ranges between 0.05 and 1.5 micrograms. The elasmobranch fish, such as sharks and rays, has a lower levels of vitamin B-12. The distribution of vitamin B-12 in the red muscle, heart, brain and liver of various fish is also shown. Content in red muscle varies between 3 and 22 micrograms, averaging 8 micrograms. The values show that the heart is a rich source of vitamin B-12. Internal organs are also rich in vitamin B

12种鳃形目鱼类mt DNA NI4 L- NI4基因的序列变异及其分子系统学

鳃形目鱼类是一类在鱼类乃至脊椎动物进化史上占有很重要地位的古老濒 危鱼类，长期悬而未决的系统演化关系为世人瞩目.采用DNA测序技术首次测定了 包括中国特有鳃形目鱼类在内的12种鳃形目鱼类的mtDNA ND4L和ND4基因(703 by)的序列，并进行了分子系统学分析.从分子系统学的角度得出了如下结论:(1) 鲤属可以归并到鳃属;(2)达氏鳃与中华鳃的亲缘关系最近，很有可能为中华鳃的 一陆封类型;(3)环太平洋地区的鳃科鱼类可能有共同的起源;(4) ND4L和ND4基 因是进行鳃形目鱼类系统演化研究很好的遗传标记.
