The floral development of the allotetraploid Coffea arabica L. correlates with a small RNA dynamic reprogramming

Societal Impact Statement This research holds potential to benefit millions of coffee-producing families in over 60 countries. We uncovered molecular regulatory mechanisms governing flower development, one of the causes for the Coffea arabica ’s uneven ripening. The absence of uniformity in coffee production, spanning from floral induction to branch senescence, has a detrimental impact on the final product’s quality. These insights will inform strategies for controlled coffee maturation, leading to improved, uniform harvests. ### Competing Interest Statement The authors have declared no competing interest.
