Likewise, in the β’1 field, there is essentially no detectable PKA activity at the immature 0 dpe time point (0.1 ± 0.05, n = 37) compared with strong signaling at 7 dpe maturity (66.8 ± 3.3, n = 38), again a highly significant elevation ( p < 0.0001; Fig. 1 E ). β’1 displays ∼2-fold more PKA activity compared with α’1.
