Soursopfruit (Annonamuricata) had received considerable interest due to its nutritional, economical, and medicinal properties, yet its commercialization has been limited due to its short post-harvest life.Nonetheless, the increase in the post-harvest shelf lifewill allow fruit exportation to international markets.Numerous studies have been carried out to elucidate the phenomena that control the duration of post-harvest of fruits. Data generated in later years, strongly indicates that the cuticle controls the post-harvest life of the fruits. The fruit cuticle is the outermost layer of the fruit, composed of high molecular weight compounds such as very long chain fatty acids, waxy alcohols and esters, long chain alkanes, ketones as well as terpenes, phenolic acids, among others.Studies with the goal to understand the molecular mechanism of cuticle biosynthesis had shown that it is regulated by a complex gene network. However, the potential role of non coding RNA in the biosynthesis and regulation of the cuticle biosynthesis have not been studied yet, to our knowledge.Several studies had shown the regulatory role in different phenomena of non-coding RNA such as the long noncoding RNAs (lncRNAs). These genetic elements are characterized by having sequences greater than 200 nucleotides (nt) and a null capacity to be translated into proteins. In plants, lncRNAs had been shown to regulate various phenomena such as fruit ripening, flowering, anthocyanin synthesis, and plant response to salt stress.
