Journal ArticleDOI
The tomato carotenoid cleavage dioxygenase 1 genes contribute to the formation of the flavor volatiles beta-ionone, pseudoionone, and geranylacetone.
TL;DR: High-performance liquid chromatography analysis showed no significant modification in the carotenoid content of fruit tissue, however, volatile analysis showed a > or =50% decrease in beta-ionone (a beta-carotene-derived C13 cyclohexone) and a> or =60% decreases in geranylacetone ( a C13 acyclic product likely derived from a lycopene precursor) in selected lines.

TL;DR: Data indicate that the substrate (s) and/or product(s) of the Dad1/PhCCD8 enzyme are mobile signal molecules with diverse roles in plant development.
Journal ArticleDOI
Feeding the world: improving photosynthetic efficiency for sustainable crop production
TL;DR: The evidence to date that manipulation of the Calvin–Benson cycle, photorespiration, and electron transport can lead to improvement in biomass and seed yield is explored.
Journal ArticleDOI
Circadian Regulation of the PhCCD1 Carotenoid Cleavage Dioxygenase Controls Emission of β-Ionone, a Fragrance Volatile of Petunia Flowers
Andrew J. Simkin,Beverly A. Underwood,Michele E. Auldridge,Holly M. Loucas,Kenichi Shibuya,Eric A. Schmelz,David G. Clark,Harry J. Klee +7 more
TL;DR: Quantitative reverse transcription-PCR analysis revealed that PhCCD1 is highly expressed in corollas and leaves, where it constitutes approximately 0.04% and 0.02% of total RNA, respectively, and indicates that Ph CCD1 activity and β-ionone emission are likely regulated at the level of transcript.
Journal ArticleDOI
SlCCD7 controls strigolactone biosynthesis, shoot branching and mycorrhiza-induced apocarotenoid formation in tomato.

TL;DR: In this article, the authors reported the cloning of SlCCD7 from tomato and demonstrated the diverse roles of these genes in strigolactone production, shoot branching, source-sink interactions and production of arbuscular mycorrhiza-induced apocarotenoids.
