Abstract
Following a zinc iodine-osmium tetroxide fixation, nuclear pore distribution was studied in 0.3-μm sections from cotyledons of developing Vicia faba L. Localised absence of nuclear pores was found to be associated with proximity of organelles to the nucleus. Golgi cisternae and mitochondria are associated with areas of pore absence while cisternal endoplasmic reticulum and tubular endoplasmic reticulum are linked with areas showing reduction in pore density. Pores were seen in the nuclear membrane adjacent to vacuoles. Pattern analysis of pore distribution indicated possible clustering within an overall regularity.Keywords
