TL;DR: It is shown that the MAX3 gene of Arabidopsis is required for the production of a graft-transmissible, highly active branch inhibitor that is distinct from any of the previously characterized branch-inhibiting hormones.

TL;DR: Unexpected properties associated with the CCD catalytic products emphasize their role in many aspects of plant growth and development and for instance, CCD7 and CCD8 produce a novel, graft-transmissible hormone that controls axillary shoot growth in plants.

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: CCD1 distinguishes itself from other reported CCDs as being the only member not targeted to the plastid, and may have a role in synthesis of apocarotenoid flavor and aroma volatiles, especially in maturing seeds where loss of function leads to significantly higher carotenoids levels.

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.
