Identification and Functional Analysis of the CgNAC043 Gene Involved in Lignin Synthesis from Citrusgrandis "San Hong".

ABSTRACT: Overaccumulation of lignin (a physiological disorder known as granulation) often occurs during fruit ripening and postharvest storage in pomelo (Citrus grandis). It causes an unpleasant fruit texture and taste. Previous studies have shown that lignin metabolism is closely associated with the process of juice sacs granulation. At present, the underlying transcriptional regulatory mechanisms remain unclear. In this study, we identified and isolated a candidate NAC transcription factor, CgNAC043, that is involved in the regulation of lignin biosynthesis in Citrus grandis, which has homologs in Arabidopsis and other plants. We used the fruit juice sacs of 'San hong' as the material, the staining for lignin with HCl-phloroglucinol of fruit juice sacs became dark red
