Abstract: | The patterns of puffing activity in polytene nuclei of salivary gland (SG) and midgut (MG) tissues of Melanagromyza obtusa have been studied after heat shock (HS), 2-4-dinitrophenol (DNP) or benzamide treatment. This study has revealed that HS and DNP treatments induced the same set of puffs but in a tissue-specific pattern. Benzamide treatment was found ineffective in inducing puffing activity. Some HS genes were also found to be more or less active during normal development, indicating some function in the normal metabolism of the cells. |
