Insertion of the PgRE1 retrotransposon into the promoter region of PgACS1, a system-2 ACC synthase gene, leads to variation in ripening ethylene production and the storability of different guava varieties

PgACS1, a System-2 1-aminocyclopropane-1-carboxylate synthase gene, is responsible for ripening-associated ethylene production in guava. This study investigated the relationships among PgACS1 genotypes, ethylene biosynthesis, and fruit storability across various guava cultivars. PCR amplification an...
