Interrelationship of mitochondria with cytoplasmic 10 nm filaments in tapetal cells of Hyacinthoides non-scripta (L.) Chouard.
An aggregation of 10 nm filamentous structures in a paracrystalline array associated with stacks of mitochondria in the tapetal cells of Hyacinthoides non-scripta (L.) Chouard is reported. The filaments are around 0.4 micrometer long and form two different types of association with mitochondria. They may be in the form of a single layer between adjacent mitochondria or packed into groups surrounded by mitochondria. The former arrangement is reminiscent of that reported for the intercisternal elements of dictyosomes. Various explanations relating to the function of tapetal cells are discussed.
