生物类英文文献中英语大写中间加双冒号代表什么

这一般是在生物类文献的基因中出现，两个基因中间加上两个冒号，原意解释如下，请参考

The three mutation strains are constructed using tet gene marker for identification and verification. Each mutation strain is showed: delta ica means a gene ice allele has been deleted in strain RN4220; agr delta means the two alleles of agr gene have been deleted, therefore agr is null in strain PC6911, and sarA gene indicates this gene is used with tet marker in construction of strain UAMS-240.

When you make some gene deletion in S. aureus isolates, or other species, you need some selection marker which is genetically linking to that of deleted gene. tet is a gene and used s a genetic marker for selecting strain with specific gene deletion.

In strain UAMS-240, one allele of sarA gene has been mutated with the integration of selecting marker tet at the locus.
