Beschreibung
Zusammenfassung:	The invention provides a novel chloroplast targeted novel beta-amylase sequence (ct beta-amylase), a novel chloroplast targeting nucleic acid sequence and a novel beta-amylase sequence. There is alsodisclosed an inducible promoter which is independently stimulated by light or sugar stimulus. Methods of transforming plants using these sequences are described, as well as transformed plant cells, transformed plants and seed thereof, as well as chimaeric genes containing the sequences. Modification of starch levels in plants can be achieved, as well as the targeting of genes from the starch biosynthetic or degradative pathways, disease or pest resistance or variation of gene expression due to stimulus are described.
