<i>sma-10</i> acts between ligand <i>dbl-1</i> and receptor <i>sma-6</i>.

aCompared to sma-10(wk89). bCompared to sma-10(wk66). cCompared to sma-6(wk7). ctIs40 is an integrated array that overexpresses a cosmid fragment containing wild-type dbl-1 promoter and gene. texEx190 is an extrachromosomal array that drives expression of a functional SMA-6:GFP fusion protein from the sma-6 promoter. The p value is the probability that the null hypothesis, that the mean body length of each mutant line is the same as the background body length, is true. “% WT” is the ratio of the indicated strain mean to the wild-type strain mean ±95% confidence interval. n, number of animals measured.
