Reversible genic male sterility in compositae

摘要

The present invention relates to plants of the Compositae family exhibiting a reversible genic male sterility trait, characterised in that the genic male sterility is caused by a reduction or complete absence of endogenous jasmonic acid production, resulting from interference with one or more target genes involved in endogenous jasmonic acid production, selected from the group consisting of lipoxygenase, allene oxide synthase, allene oxide cyclase and 12-oxo-phytodienoic acid-10,11-reductase, or their functional homologues.
