This article investigates the relationship between RNA editing and plant cellular stress as well as electron transport organelles. Through the analysis of cDNAs from the mitochondrial atp1 gene of two wheat cultivars, it was found that RNA editing is influenced by drought stress conditions and leads to changes in synonymous amino acids of the protein without altering its tertiary structure.
There is evidence that RNA editing is related to plant cellular stress as well as electron transport organelles, such as mitochondria. The mitochondrial atp1 gene encodes the alpha-subunit of Atp synthase. Control as well as two periods of drought stress treatments were analyzed in the cDNAs generated from the mitochondrial atp1 gene of two cultivars of Triticum aestivum [Giza 168 (G168) and Gemmiza 10 (GM10)]. Following RNA-seq data assembly, atp1 cDNAs from the control (acc. no. OQ129415), 2-hour (acc. no. OQ129416), and 12-hour (acc. no. OQ129417) time points of the T. aestivum cultivar G168 were obtained. Control (acc. no. OQ129419), 2-hour (acc. no. OQ129420), and 12-hour (acc. no. OQ129421) samples all included reconstructed atp1 transcripts from Gemmiza 10. Atp1 transcripts were assembled using the wheat atp1 gene (acc. no. NC_036024). RNA-seq raw data was utilized to identify 11 RNA editing sites in atp1 in the tolerant cultivar Giza168 and 6 in the sensitive cultivar Gemmiza10. The significant difference in RNA editing observed between control and drought stress conditions in sites led to synonymous amino acids. This led to no change in tertiary structure between tolerant and sensitive cultivars. But the change was focused between produced protein and its correspondence sequence on DNA.& COPY; 2023 The Author(s). Published by Elsevier B.V. on behalf of King Saud University.
