Downregulation of a chloroplast-targeted beta-amylase leads to a starch-excess phenotype in leaves.

The Plant journal : for cell and molecular biology - 1 Jun 2002

Abstract excerpt

A functional screen in Escherichia coli was established to identify potato genes coding for proteins involved in transitory starch degradation. One clone isolated had a sequence very similar to a recently described chloroplast-targeted beta-amylase of Arabidopsis. Expression of the gene in E. coli showed that the protein product was a functional beta-amylase that could degrade both starch granules and solubilized...
