Molecular genet­ics of cuticle form­a­tion in Prunus

During growth, the fruit sur­face of sweet cherry, Prunus avium, expands rap­idly whilst only a rel­at­ively small amount of new cutic­u­lar mater­ial is pro­duced, often lead­ing to the form­a­tion of micro­scopic cracks in the cuticle that can reduce fruit qual­ity. Alkio et al. per­form RNA-Seq and bioin­form­atic ana­lyses to identify genes expressed in the skin of devel­op­ing fruit, and relate gene expres­sion with cuticle depos­ition. The res­ults sug­gest that down­reg­u­la­tion of genes involved in cuticle depos­ition occurs early in fruit devel­op­ment, and a num­ber of can­did­ate genes are pro­posed for fur­ther investigation.

    Interesting. I am won­der­ing if the down­reg­u­la­tion of cuticle depos­ition is con­sidered a norm for the sweet cherry. If so, what would be the evol­u­tion­ary bene­fit? Is it pos­sible that the cracks in the cuticle help attract poten­tial organ­isms, like rodents, that would help spread the seeds through ingestion.
