abstract: Figure 10 on page 351 of the Research Article "Constitutive and conditional suppression of exogenous and endogenous genes by anti-sense RNA" by J. G. Izant and H. Weintraub (26 July, p. 345) was reproduced erroneously, so that the green stain (NBD-phallacidin) of the actin filaments was not chromatically resolved. The micrographs are intended to document the specific disruption of the actin microfilament distribution, while the RNA and DNA staining pattern (orange-red) was unaffected. The correct figure and legend appear below.
