Auxin signaling is elevated in zll-1 embryos. a Expression of the stem cell markers pCLV3:erCFP, pRPS5a:mDII-ntdTomato (ntdTomato), and pRPS5a:DII-n3xVenus (DII-Venus) in embryos at the indicated stages and genotypes. The erCFP signal was recorded with 1,000 ms exposure time, ntdTomato with 400 ms, and DII-Venus with 3,000 ms for all samples. The CFP signal is shown in blue, DII-Venus in yellow, and ntdTomato in red. Scale bars: 10 μm for transition to heart stages, 30 μm for torpedo and bent-cotyledon stages. b DII-Venus to ntdTomato signal ratios during embryogenesis. ***p <0.001; n.s. not significant
