Mutations in EID1 and LNK2 caused light-conditional clock deceleration during tomato domestication

Significance Internal timekeepers, called circadian clocks, are prevalent in all domains of life. Variation in circadian rhythms allows fine-tuning of an organism to its specific environment. Here we show that a mutation in LNK2 , in addition to the already described mutation in EID1 , was responsible for the deceleration of circadian rhythms in cultivated tomatoes. We show that the mutant alleles of both genes arose in the earliest cultivated...
