Abstract
Observations on Tradescantia cells in the second meiotic division revealed distinct regions in meiotic chromosomes. These areas 1) consistently stain less dense than the chromosomes themselves, 2) have direct connections with the chromosomes at certain points, and 3) serve as focal points for spindle tubules during meiosis. These lighter staining regions are similar in character to kinetochores (centromeres) found in animal cells. Es wurde beobachtet, daß bestimmte Regionen der Chromosomen von Tradescantia zu der zweiten meiotischen Teilung 1. durchgängig sich weniger stark färben als die Chromosomen selbst, 2. daß sie an gewissen Punkten direkte Verbindungen mit den Chromosomen haben, und 3. daß sie während der Meiosis als Sammelpunkte für Spindeltubuli dienen. Diese schwächer gefärbten Stellen werden als Kinetochoren (Centromeren) interpretiert.Keywords
