Firming up your tomato: a natural promoter variation in a MADS-box gene is causing all-flesh tomatoes.

MADS-domain transcription factors are central regulators of fruit development. Understanding how they function in crop plants can provide valuable insights for research and agriculture. Employing genetic mapping, Liu et al. (2021) uncovered a naturally occurring mutation causing the inhibition of locule formation resulting in all-flesh tomatoes. The causal mutation is located in the cis-regulatory region of the SEEDSTICK-like tomato MADS-box gene termed ALL FLESH FRUITS (AFF), underlining the vast potential of cis-regulatory elements for traditional plant breeding as well as for biotechnology.
