Strigolactone inhibition of shoot branching
Evidence is presented that carotenoid cleavage dioxygenase 8 shoot branching mutants of pea are strigolactone deficient and that strigOLactone application restores the wild-type branching phenotype to ccd8 mutants, and that other branching mutants previously characterized as lacking a response to the branching inhibition signal also lack striglactone response.
The Path from β-Carotene to Carlactone, a Strigolactone-Like Plant Hormone
Knowledge of the structure of carlactone will be crucial for understanding the biology of strigolactones and may have applications in combating parasitic weeds.
Terpenoid Metabolism in Wild-Type and Transgenic Arabidopsis Plants Online version contains Web-only data. Article, publication date, and citation information can be found at…
The value of Arabidopsis for studies of the biosynthesis and ecological role of terpenoids is demonstrated and new insights into their metabolism in wild-type and transgenic plants are provided.

Transgenic Arabidopsis thaliana plants emitted two new isoprenoids that attracted carnivorous predatory mites that aid the plants' defense mechanisms, and metabolic engineering of terpenoids holds particular promise.
Physiological Effects of the Synthetic Strigolactone Analog GR24 on Root System Architecture in Arabidopsis: Another Belowground Role for Strigolactones?1[C][W][OA]
It is proposed that the tightly balanced auxin-strigolactone interaction is the basis for the mechanism of the regulation of the plants’ root-to-shoot ratio and that the net result of strigolACTone action is dependent on the auxin status of the plant.

For these three host and two parasitic plant species, the strigolactone germination stimulants are derived from the carotenoid pathway, and this finding is discussed as an explanation for some phenomena that have been observed for the host-parasitic plant interaction.
Gain and Loss of Fruit Flavor Compounds Produced by Wild and Cultivated Strawberry Species
Processes that may have been responsible for the evolution of diversity in strawberry (Fragaria spp) fruit flavor components are reported on.
Identification of the SAAT Gene Involved in Strawberry Flavor Biogenesis by Use of DNA Microarrays
The results suggest that the formation of volatile esters in fruit is subject to the availability of acyl-CoA molecules and alcohol substrates and is dictated by the temporal expression pattern of the SAAT gene(s) and substrate specificity of theSAAT enzyme(s).
Redefining seed dormancy: an attempt to integrate physiology and ecology
A concept of seed dormancy in which physiology and ecology are integrated is presented, partly based on a physiological model for the regulation of dormancy and the stimulation of germi nation.

The in planta activity of an alcohol acyltransferase and the potential for metabolic engineering of ester production were assessed, confirming that the availability of alcohol substrates is an important parameter to consider when engineering volatile ester formation in plants.
