Model of the transcriptional regulatory module PuNAC21–PuDof2.5 regulates Ca2+-mediated lignin biosynthesis in pear. Ca2+ inhibits lignin synthesis and decrease stone cell content in pear fruit development through three pathways: (1) Ca2+-induced PuNAC21 suppressing PuPRX42-like transcription activity to reduce lignin synthesis. (2) Ca2+ weakens the transcription of PuDof2.5 by PuNAC21, thereby inhibiting the expression of PuPRX42-like and PuCCoAOMT1 to reduce lignin synthesis. (3) Ca2+ suppressed the transcription of PuPRX42-like and PuCCoAOMT1 by weakening the interaction between PuNAC21 and PuDof2.5, leading to reduce lignin synthesis.
