Nonindependent domestication of the two rice subspecies, Oryza sativa ssp. indica and ssp. japonica, demonstrated by multilocus microsatellites, pp. 965-976 Li-zhi Gao and Hideki Innan Controversy over the origins of the Asian cultivated rice Oryza sativa from its wild ancestor O. rufipogon has centered on a monophyletic or polyphyletic origin. Proliferating cell nuclear antigen and ASF1 modulate silent chromatin in Saccharomyces cerevisiae via lysine 56 on histone H3, pp. 793-809 Andrew Miller, Bo Yang, Tiaunn Foster and Ann L. Kirchmaier Post-translational modifications of histones are usually associated with transcription, but this article demonstrates that K56- acetylated histone H3 affects gene silencing in yeast through the replication factors proliferating cell nuclear antigen and RF-C and the chromatin assembly factor Asf1.
