Cereal asparagine synthetase genes

Abstract: Asparagine synthetase catalyses the transfer of an amino group from glutamine to aspartate to form glutamate and asparagine. The accumulation of free (nonprotein) asparagine in crops has implications for food safety because free asparagine is the precursor for acrylamide, a carcinogenic contaminant that forms during hightemperature cooking and processing. Here we review publicly available genome data for asparagine synthetase genes from species of the Pooideae subfamily, including bread wheat and related wheat… Show more

“…spelta) to characterise natural allelic variation in the wheat asparagine synthetase gene family. The results are shown in Table 1, ordered by gene name [14,15] and the corresponding annotated gene model ID from the Chinese Spring RefSeq v1.1 genome assembly [20]. For each orthologous gene, Sorting Intolerant From Tolerant (SIFT) analysis was performed on the translated protein to predict whether the variation in amino acid sequences was likely to disrupt protein function (highlighted in yellow in Table 1) or to be tolerated (highlighted in green).…”

“…Asparagine is synthesised by the transfer of an amino group from glutamine to aspartate to make asparagine and glutamate in a reaction catalysed by asparagine synthetase. The cereal asparagine synthetase gene family comprises between two and ve genes per diploid genome [14], with members of the Triticeae tribe all having ve genes per genome, assigned to four groups: 1, 2, 3 (subdivided into 3.1 and 3.2) and 4. The one documented exception is that some hexaploid common wheat (Triticum aestivum L.; genomes AABBDD) and tetraploid emmer wheat (T. turgidum; genomes AABB) genotypes lack a group 2 gene in the B genome (TaASN-B2/TdASN-B2) [14,15].…”
