Fig. 4. Overexpression of ERV15 suppresses the sporulation defect of an erv14
mutant. Wild-type (AN120) cells harboring the empty vector pRS424, or erv14
/erv14
(H126) cells harboring pRS314-ERV14HA, pRS424-ERV15 or empty vector were sporulated and 3x105 cells were spotted onto a YPD plate, exposed to ether vapor and incubated at 30°C.
