Effects of Membrane ATPase Inhibitors on Light-Induced Phase Shifting of the Circadian Clock in Neurospora crassa.

abstract：:Polyacetylenic lipids accumulate in various Apiaceae species after pathogen attack, suggesting that these compounds are naturally occurring pesticides and potentially valuable resources for crop improvement. These compounds also promote human health and slow tumor growth. Even though polyacetylenic lipids were discove...
