Analysis of β-amylase gene (Amyβ) variation reveals allele association with low enzyme activity

and increased firmness in cooked sweetpotato (Ipomoea batatas) from East Africa

Abstract

Sweetpotato β-amylase gene sequence varied amongst study genotypes. Genotypes with mutations within exon V and intron V of β-amylase gene were identified. First report of a β-amylase gene mutation associated with low enzyme activity in sweetpotato roots. β-amylase activity was negatively correlated with firmness in cooked sweetpotato roots.
