Phenotypic rescue by overexpression of sma-9 short transcripts. A. Male tail phenotypes are given as frequency of fusion of rays 8 and 9 per male tail side scored. p values were calculated using a Student's t-test. *: significant difference from no cDNA control (p < 0.05). **: highly significant difference from no cDNA control (p < 0.01). The p values for experiments with A11 cDNA overexpression showed no significant difference from controls (p = 0.59 for qc3; p = 0.16 for cc604). All strains contain him-5(e1490) to increase the proportion of males. B. Body size phenotypes. Mean body length at 96 hours after embryo collection (adult stage) is shown. Error bars show standard deviation. Note that these strains are transgenics expressing the rol-6 marker that influences body length, so all comparisons are made between heat-shocked animals and no heat shock control rather than using a nontransgenic control. p values were calculated using a Student's t-test. **: highly significant difference from no heat shock control (p < 0.01).
