LncRNA-encoded peptides: the case of the lncRNA gene located downstream of EIN2

The long non-coding RNAs (lncRNAs) are a group of heterogeneous regulatory RNA greater than 200 nucleotides (nt) in length with a low evident protein coding. These molecules are important regulators because they can function both in cis or in trans in the genome or interact with other RNAs and proteins (Nagano and Fraser 2011; Bhogireddy et al. 2021); also with the genome position and the relation with other genes, they are classified as an antisense orientation, intronic, promoter, and intergenic (Ariel et al. 2015). The lncRNAs are transcribed by RNA polymerase II, IV, and V; also, their polyadenylation could be missing and located in the nucleus, cytoplasm, or both (Lucero et al. 2020). Although it has been argued that lncRNA and microRNAs transcripts preferentially act as functional RNAs (Ben Amor et al. 2009), recently, not only in mammals but also in plants, it has been proved that surely many of them …
