CHLORTETRACYCLINE‐INDUCED FORMATION OF WALL APPOSITIONS (CALLOSE PLUGS) IN INTERNODAL CELLS OF NITELLA FLEXILIS (CHARACEAE) 1
ABSTRACT The formation of chlortetracycline (CTC)‐induced wall appositions or plugs in internodal cells of Nitella flexilis (L.) Ag. was studied with light, fluorescence and electron microscopy. These plugs contain callose and pectin. A few minutes after CTC addition plug formation starts by fusion...
