Cytomixis in Pollen Mother Cells of Citrus Genotypes
A microsporogenesis analysis performed in several Citrus populations revealed the presence of cytomixis (i.e., chromatin migration between meiocytes) in pollen mother cells of diploid and tetraploid genotypes. Single and double chromatin bridges between adjacent meiocytes were mainly observed at prophase I, but also in the subsequent phases of first division and in the second meiotic division. ...

متن کاملAn Apparent Helical Arrangement of Ribosomes in Developing Pollen Mother Cells of Ipomoea Purpurea (l.) Roth
Behnke (1963) has recently described a helical arrangement of ribosomes in differentiating cells of the small intestine of the rat fetus, and Waddington and Perry (1963) have found the same structures in the muscle cells of Rana pipiens embryo. In the course of an investigation into the development of pollen in Ipomoea purpurea (L.) Roth, a similar arrangement of ribosomes has been seen in the ...
