Tomato plant comprising a mutant <i>tghVI </i>allele

摘要

The present invention relates to a tomato plant (Solanum lycopersicum L.) in which the glandular heads of type VI trichomes are absent, and that has a modified composition of flavonoids and volatiles. Furthermore, the typical tomato smell is absent or nearly absent. The plant comprises a mutant allele, which is obtainable from a tomato plant, representative seed of which was deposited under deposit accession number NCIMB 41845. The said mutant allele is located on chromosome 9 between positions 1750800 bp and 4517648 bp, preferably between positions 1939546 bp and 2970346 bp, most preferably at about position 2454946 bp on a physical map of the Solanum lycopersicum genome.

主权项

1. A tomato plant that is characterized by the following features:
as compared to a wild type or isogenic control plant, the plant does not comprise or has at least a reduced number of the glandular cells of type VI trichomes, as compared to a wild type or isogenic control plant, the plant has a reduced level of one or more terpenes, sesquiterpenes and/or aldehydes, and as compared to a wild type or isogenic control plant, the plant does not comprise or has at least a reduced level of flavonoids, wherein the plant carries a mutant tghVI allele on chromosome 9 which, in the genome of the seeds of which a representative sample was deposited under accession number NCIMB 41845, is linked to a molecular SNP marker at position 1750800 of the public physical map SL2.30, wherein the SNP marker has a nucleotide change from A to G.
