Functional Descriptions:

  • Overexpression of tomato SlNAC1transcription factor alters fruit pigmentation and softening.
  • Tissue-specific analysis by quantitative real-time PCR showed that SlNAC1 was highly accumulated in immature green fruits| the expression of SlNAC1 increased with fruit ripening till to the highest level at 7 d after the breaker stage.
  • The overexpression of SlNAC1 resulted in reduced carotenoids by altering carotenoid pathway flux and decreasing ethylene synthesis mediated mainly by the reduced expression of ethylene biosynthetic genes of system-2, thus led to yellow or orange mature fruits.
  • Overexpression of SlNAC1 reduced the firmness of the fruits and the thickness of the pericarp and produced more abscisic acid, resulting in the early softening of fruits.
  • SlNAC1, a stress-related transcription factor, is fine-tuned on both the transcriptional and the post-translational level.
  • We present evidence implicating SlNAC1, a new member of the NAC domain protein family from tomato (Solanum lycopersicum), in Tomato leaf curl virus (TLCV) REn function.
  • Hence, in SlNAC1 overexpression lines, both ethylene-dependent and abscisic acid-dependent pathways are regulated by SlNAC1 in fruit ripening regulatory network.
