"pinpoint colonies"
Thank you for the xeroprint[?]
I wrote you b/c[?] your title hinted you were looking into metal-"induced" small colony variants, cf.
Weed, L.L. J. Bact. 67:27 (1954) ("induced" by copper.)
One of my students looked into this at the time, rather fruitlessly.
Your paper gives no support to that dosewater;[?] but failure to get his + phenotypes on replica-plotting doesn't really exclude it.
Enclosed a more novel wrinkle on metal resistance, via gene amplification. The connection to mutagenic induction is remote (if any.)
Yours,
Josh Lederberg
