Characterization of Geraniol Synthase from the Peltate Glands of Sweet Basil1
Geraniol synthase (GES) activity was shown to be localized exclusively or almost exclusively to glands, and RNA gel-blot analysis indicated that GES is expressed in glands but not in leaves of basil cv Sweet Dani, whose glands contain geraniol and citral, and not in glands or leaves of another basil variety that makes other monoterpenes but not Geraniol or citral.

Metabolite annotations based on the integration of mass spectral information
Based on the comprehensive characterization of tomato fruit metabolites, it is demonstrated that metabolite annotation facilitates the systematic analysis of unknown metabolites and biological interpretation of their relationships, which provide a basis for integrating metabolite information into the system-level study of plant biology.

The Biochemical and Molecular Basis for the Divergent Patterns in the Biosynthesis of Terpenes and Phenylpropenes in the Peltate Glands of Three Cultivars of Basil1
Three distinct basil chemotypes were used to examine the molecular mechanisms underlying the divergence in their monoterpene and sesquiterpene content, and the relative levels of specific terpenes in the glandular trichomes of each cultivar were correlated with the levels of transcripts for eight genes encoding distinct terpene synthases.

GLYCOALKALOID METABOLISM1 Is Required for Steroidal Alkaloid Glycosylation and Prevention of Phytotoxicity in Tomato[W]
The role of GLYCOALKALOID METABOLISM1 (GAME1) in the biosynthesis of tomato SAs was revealed, highlighting the importance of GAME1 in SA glycosylation and in reducing the toxicity of SA metabolites to the plant cell. Expand
Metabolic, Genomic, and Biochemical Analyses of Glandular Trichomes from the Wild Tomato Species Lycopersicon hirsutum Identify a Key Enzyme in the Biosynthesis of Methylketonesw⃞
Levels of MKS1 transcript, protein, and enzymatic activity were correlated with levels of methylketones and gland density in a variety of tomato accessions and in different plant organs. Expand
Biochemical mechanism on GABA accumulation during fruit development in tomato.
The results suggest that GAD and GABA-TK play crucial roles in GABA accumulation and catabolism, respectively, in tomato fruits. Expand
Enzymatic Functions of Wild Tomato Methylketone Synthases 1 and 21[W][OA]
It is concluded that ShMKS2 acts as a thioesterase hydrolyzing 3-ketoacyl-acyl carrier proteins (plastid-localized intermediates of fatty acid biosynthesis) to release 3- Ketoacids and that ShmKS1 subsequently catalyzes the decarboxylation of these liberated 3- ketoacid products, forming the methylketone products.

Intake and transformation to a glycoside of (Z)-3-hexenol from infested neighbors reveals a mode of plant odor reception and defense
Undamaged tomato plants exposed to volatiles emitted by conspecifics infested with common cutworms became more defensive against the larvae than those exposed tovolatiles from uninfested conspespecifics (control plants) in a constant airflow system under laboratory conditions. Expand
Neuronal cell type–specific alternative splicing is regulated by the KH domain protein SLM1
Cell type–specific expression of the splicing regulator SLM1 provides a mechanism for shaping the molecular repertoires of synaptic adhesion molecules in neuronal populations in vivo.
Analysis of the enzymatic formation of citral in the glands of sweet basil.
Identification of two basil cDNAs encoding NADP+-dependent dehydrogenases that can use geraniol as the substrate and the presentation of additional data presented indicate that basil glands may contain additional dehydrogenase capable of oxidizing Geraniol. Expand
