Intraspecific crosses

[cbirky at MAGNUS.ACS.OHIO-STATE.EDU]

Does anyone know of attempts to do "interspecific" crosses with
Chlamydomonas, other than eugametos X moewusii and reinhardtii X smithii?
Or of crosses between isolates believed to belong to the same species but
showing some divergence of DNA sequences?  We are interested in data
relating sequence divergence to reproductive isolation (or the lack
thereof).
