Tartalmi leírás:
Cytomixis has been described in many plant species, but not in
Thinopyrum
. The present study reports spontaneous cytomixis during microsporogenesis in
Thinopyrum intermedium
(2n = 42),
Thinopyrum ponticum
(2n = 70), and their F
<sub>1</sub>
hybrids with wheat. Cytomixis frequently occurred in early prophase I but very rarely in meiosis II. The type of cytomixis that occurred most often was where chromatins migrate from one nucleus into an adjacent cel1. Migration from one nucleus into two or more cells or from two or more nuclei into one cel1 was also observed. After a donor cell transferred chromatin to a recipient cell, the recipient cell would sometimes pass the chromatin on to another cell. Migration did not necessarily occur between cells in the same stage. Cytomixis in
Th. ponticum
and its hybrids with wheat was more complex than that in
Th. intermedium
. The possible causes, cytological consequences and genetic significance of cytomixis are discussed.
