Transient expression analysis of different lengths 5′ of sox9b. Lateral images of 96 hpf zebrafish from transient experiments using the indicated promoter sequences. Newly fertilized eggs were injected as described in the Materials and methods, and images were recorded using confocal microscopy showing EGFP reporter expression as green fluorescence. Abbreviations: brain, b; heart, h; jaw, j; skeletal muscle, m; and notochord, n. The + indicates consistently observed; the - indicates consistently not observed; +/- indicates sporadic or weak occurrence in offspring.
