Genetic control of Drosophila virilis tyrosine decarboxylase activity

Tyrosine decarboxylase (TDC) activity was studied in flies of two Drosophila virilis lines having contrasting response to stress. Lines 101 and 147 exhibited different TDC activity. Genetic analysis of these differences was performed. TDC activity was shown to be controlled by one gene or a block of...

Description
Summary:	Tyrosine decarboxylase (TDC) activity was studied in flies of two Drosophila virilis lines having contrasting response to stress. Lines 101 and 147 exhibited different TDC activity. Genetic analysis of these differences was performed. TDC activity was shown to be controlled by one gene or a block of tightly linked genes. The gene controlling TDC activity was mapped to one autosome but not to chromosome 2. In line 101, short-term heat stress (38 degrees C, 60 min) resulted in reduction in TDC activity, whereas, in line 147, this activity remained unchanged.
