Correction: The GATA Factor elt-1 Regulates C. elegans Developmental Timing by Promoting Expression of the let-7 Family MicroRNAs.

There are errors in Table 1. The trans-heterozygous genotypes under ‘’ are not displayed in the standard way; + should be ku491/+, + should be ok1002/+ and ok1002 should be ku491/ok1002. The correct table is displayed underneath.

Table 1

elt-1 mutants have an L4-stage bursting vulva and defective alae formation and elt-1(ku491) is a partial loss-of- function allele.

aPhenotypes on empty-vector control RNAi were similar to the standard E. coli strain OP50.

bAn allele of elt-1(ku491) linked to mutations in unc-24 and dpy-20 was used for these strains.

cFor elt-1(ku491) animals vs elt-1(ku491)-over-elt-1(null) animals at the young adult stage, the p-value for the comparison of seam-cell numbers is 0.0340

dFor elt-1(ku491);daf-12(rh61rh411) animals vs elt-1(ku491)-over-elt-1(null);daf-12(rh61rh411) animals at the young adult stage, the p-value for the comparison of seam-cell numbers is < 0.0001.
