Cloning the full-length CDNA of actin gene and analysing alliinase gene expression in tillering onion

Biosci. j. (Online); 39 (), 2023
Tillering onion is a herbaceous plant belonging to the Liliaceae family. We cloned the cDNAs of the actin gene (AcACT, GenBank: MF919598) of tillering onion using rapid amplification of the cDNA ends. The full-length cDNA of AcACT was 1,357 bp long with an open reading frame of 1,131 bp encoding 376 amin...
