Genotype abbreviations

Hello!

In microbiology you often encounter abbreviations - for restriction
enzymes, for resistance genes and other genes. Whereas a list of
restriction enzymes with their abbreviations can be found in lots of
literature, I was not able to find such a list for genes and their
abbreviations.

For example the (mutation) genotype of the E. coli strain JM109 is
indicated as follows:

JM109  endA1, recA1, gyrA96, thi1, hsdR17(rk-,mk+), relA1, supE44,
delta(proAB, lac), F'[proAB, laclq, lacZ(deltaM15), traD]

Unfortunately I could not use the appropriate formatting (italics,
sub-/superscript, greek letters) here. But I think you can read it
anyway.

Some of the abbreviations are easy to be guessed. But I do not know all
of them. I have to know the strain's phenotypic traits, so I should know
what all the abbreviations mean and how they affect metabolism or other
processes in the strain.
So does anybody know where I can look up for this sort of abbrevations?

Note: Explaining the abbreviations in the above strain would help me a
little, but I would prefer a reference to where I can find a list of
this kind of abbreviations because the JM109 strain is just an example
and I have others strain with other abbreviations.

I wonder why they do not explain these abbreviations in most literature.
Is an experienced microbiologist (which I am not) expected to know them?
If yes, where did he/she learn about them?
