Biosynthesis, Extraction, Purification, and Analysis of Trisporoid Sexual Communication Compounds from Mated Cultures of Blakeslea trispora
Time of Update: 2021-02-22
The zygomyceteBlakeslea trispora produces high amounts of the general zygomycete β-carotene-derived sexual signal compounds, the trisporoids.
The effect of the extraction and activity of the isolated compounds is best tested physiologically, exploiting the ability of trisporoids to induce the formation of sexually committed hyphae, the zygophores, in other zygomycete species.
