Autoradiographic studies on RNA synthesis and transport in the salivary gland of Lygaeus sp. (Hemiptera-Lygaeidae).
Autoradiographic studies using 3H-uridine in the salivary gland of adult Lygaeus sp. were carried out. The gland cell nuclei, particularly the multiple nucleoli, are the sites of incorporation of the label exhibiting RNA synthesis. The labelled molecules (RNA) are transported to the cell cytoplasm and then into the gland lumen in which no turnover of the radioactivity is observed.
