Bioinformatics Analysis Reveals PPR Genes Modulation by Ahyp-miR0005 Under Abiotic Stress Across Diverse Plant Species.

ABSTRACT: MicroRNAs (miRNAs) play a critical role in gene regulation in plants. Several members of the pentatricopeptide repeat (PPR) family have been identified as predicted targets of Ahyp-miR0005, a miRNA specific to amaranth. PPR proteins are essential for mitochondrial and chloroplast biogenesis, as well as plastid-to-nucleus communication, processes fundamental for retrograde signaling between the plastid and nucleus (RSBPN). In this study, we identified the target of Ahyp-miR0005 and its association with the PPR protein family across Amaranthus hypochondriacus, Arabidopsis thaliana, Nicotiana tabacum, and Solanum lycopersicum. Cleavage inhibition by Ahyp-miR0005 was predicted, and the distribution of miRNA binding sites per target gene was analyzed, including their
