The disclosure provides an isolated nucleic acid molecule encoding a 7-epizingiberene synthase, a chimeric gene comprising said nucleic acid molecule, vectors comprising the same, as well as isolated 7-epizingiberene synthase proteins themselves. In addition, transgenic plants and plant cells comprising a gene encoding a 7-epizingiberene synthase, optionally integrated in its genome, and methods for making such plants and cells, are provided. Especially Solanaceae plants and plant parts (seeds, fruit, leaves, etc.) with enhanced insect pest resistance are provided.

Pest resistant plants

The present invention relates to identification and isolation of zinc finger transcription factor in tomato that specifically expresses in glandular trichomes ofcultivar Moneymaker and binds to the promoters of the genes encoding Terpene Synthase 5 (also known as Monoterpene Synthase 1) and Terpene Synthase 11 (also known as Sesquiterpene Synthase 1). The invention provides the isolated, recombinant or synthetic polynucleotides encoding the polypeptide sequences of SEQ ID NO:2 and variants and fragments thereof. The invention also provides constructs, vectors, host cells and plants genetically modified to contain the polynucleotides of the invention. The methods for producing plants with altered levels of terpenes, including transformed and mutant plants, are also provided.

Trichome-specific transcription factor modulating terpene biosynthesis

An isolated nucleic acid molecule encoding a 7-epizingiberene synthase, a chimeric gene comprising the nucleic acid molecule, vectors comprising the same, as well as isolated 7-epizingiberene synthase proteins themselves, are provided. In addition, transgenic plants and plant cells comprising a gene encoding a 7-epizingiberene synthase, optionally integrated in its genome, and methods for making such plants and cells, are provided. Especially Solanaceae plants and plant parts (seeds, fruit, leaves, etc.) with enhanced insect pest resistance are provided.

A new farnesene synthase was isolated from tomato. The farnesene synthase shows surprising properties with regard to the end products formed and its gene has, on a nucleotide level, low sequence identity with known farnesene synthase genes from other sources. The invention relates to isolated polynucleotides, polypeptides encoded by said polynucleotides, genetic constructs, vectors, hosts, in particular plants, harboring such polynucleotides, polypeptides and genetic constructs, and seed derived from such plants.
