The present invention is related to a family of novel spatiotemporally
active Rubisco promoters (SEQ ID NO: 1, 2, 3) obtainable from light grown
Brassica seedlings. Furthermore the invention is related to transgene
expression in specific plant organs or at specific stages of plant
development. DNA constructs and expression cassettes comprising at least
one of the promoter sequences functionally fused in frame with genes
encoding desired gene products are disclosed. Seeds from transformed
homologous and herterologous plants and from subsequent generation of the
transformed plants are collected and used for efficient production of
desired gene products, especially in contained conditions.
