It was determined that lycopene could be cyclized directly by Rhodotorula glutinis . It was also shown the the temperature effect (i.e., increased β-carotene synthesis in response to lower incubation temperatures) in R. glutinis was controlled by changes in enzyme concentration.

The treatment of young guayule plants with 2-(3,4-dichlorophenoxy)-triethylamine stimulated the accumulation of polyisoprenoid rubber in the stem and root tissues. This finding suggests that rubber productivity can be improved by the use of chemical agents on guayule and other rubber-forming plants.
