GENETICS. For the article “Blocking histone deacetylation in Arabidopsis induces pleiotropic effects on plant gene regulation and development” by Lu Tian and Z. Jeffrey Chen, which appeared in number 1, January 2, 2001, of Proc. Natl. Acad. Sci. USA (98, 200–205; First Published December 26, 2000; 10.1073/pnas.011347998), the authors note the following. In Fig. 2 and the legend, yeast RPD3 has 433 amino acids, not 201 as indicated. On page 201, right column, paragraph 4 in Results, the statement that the C terminus of the AtHD1 is specific to multicellular organisms is incorrect.
