(A) Western blot analysis of H3K79 methylation species in
vegetative (T=0h) and meiotic cells (T=20h). Total H3 and PGK were used
as loading controls.
(B) Quantification of relative levels of the H3K79
methylation forms at T=0 from the blots shown in (A). Total H3 signal
was used for normalization.
(C) Time course of meiotic nuclear divisions; the percentage
of cells with two or more nuclei is presented. Strains are DP422
(zip1), DP995 (zip1 H4-K16R) and
DP1001 (zip1 H4-K16Q), transformed either with an empty
vector or with the high-copy pSS63 DOT1 overexpression
plasmid (DOT1-OE).
