Abstract excerpt

Seed germination is a crucial transition in spermatophytes, regulated by gibberellins (GAs). GA levels are controlled by GA2-oxidases (GA2ox), but how DNA methylation participates in this regulation remains unclear. Here, we identified the tomato methyl-CpG-binding domain (MBD) protein SlMBD5 as a regulator of seed germination. The slmbd5 mutant exhibits delayed germination and reduced GA4/GA7 levels, which can...
