1 Recently, we have discovered a novel regulatory mechanism of cuticular wax biosynthesis that involves the ECERIFERUM7 (CER7) ribonuclease, a core subunit of the exosome. Waxes 3'-5'-exoribonuclease family protein Arabidopsis thaliana
2 Recently, we have discovered a novel regulatory mechanism of cuticular wax biosynthesis that involves the ECERIFERUM7 (CER7) ribonuclease, a core subunit of the exosome. Waxes 3'-5'-exoribonuclease family protein Arabidopsis thaliana
3 We hypothesized that at the onset of wax production, the CER7 ribonuclease degrades an mRNA specifying a repressor of CER3, a wax biosynthetic gene whose protein product is required for wax formation via the decarbonylation pathway. Waxes 3'-5'-exoribonuclease family protein Arabidopsis thaliana
4 We hypothesized that at the onset of wax production, the CER7 ribonuclease degrades an mRNA specifying a repressor of CER3, a wax biosynthetic gene whose protein product is required for wax formation via the decarbonylation pathway. Waxes 3'-5'-exoribonuclease family protein Arabidopsis thaliana
5 To identify the putative repressor of CER3 and to unravel the mechanism of CER7-mediated regulation of wax production, we performed a screen for suppressors of the cer7 mutant. Waxes 3'-5'-exoribonuclease family protein Arabidopsis thaliana
