Abstract excerpt
The phragmoplast dysfunction in wheat x rye hybrid F1 male meiosis has been described. The pollen mother cells (PMCs) show the phenotype where transition from central spindle fibers (forming a solid bundle) to a phragmoplast (hollow cylinder) is blocked. The blockade suppresses centrifugal movement of the phragmoplast and cell plate formation. The resulting cells occur to be binucleate. Sometimes, the two nuclei...
