Abstract: This invention relates to fertilizer and herbicide compositions. The present invention provides a composition for selective fertilization of a transgenic plant comprising a polypeptide which metabolizes a D-amino acid substrate; said composition comprising said D-amino acid substrate. Another aspect of the present invention provides a selective herbicide composition comprising a D-amino acid. Such a herbicide will inhibit or reduce the growth of plants which do not contain the appropriate D-amino acid metabolizing enzyme, while the growth of transgenic plants which are able to metabolize the D-amino acid will be unaffected or, more preferably, be increased or enhanced. Methods and means are also provided for selectively modulating the growth and stress tolerance such plants using D-amino acids. The methods can be used either for detoxification of phytotoxic D-amino acids such as D-alanine and D-serine, thereby allowing for selection of plants comprising said D-amino acid metabolizing enzymes, or for enhancing toxicity of lesser phytotoxic D-amino acids such as D-isoleucine, thereby allowing for selection of plants not comprising said D-amino acid metabolizing enzymes.

Abstract: Tissue specific promoters (SEQ. ID. No. 1-5) are disclosed, these being preferentially expressed in the xylem tissue of woody plants. These promoters are used e.g. to specifically regulate gene expression in xylem tissue and alter xylem properties in plants. Transgenic plants, exhibiting modified xylem properties can be produced using these promoters.
