Synaptonemal complex (SC) formation in microsporocytes of Allium ursinum is severely affected by exposure of plants to 35° C for 30 h or longer. In spread preparations made from fresh and freeze-conserved material it was found that a high proportion of meiocytes is arrested at leptotene and shows no synapsis at all. In another group of nuclei synaptonemal polycomplex-like structures do occur between converging axial elements at presumed rudimentary SC initiation sites. Axial elements are… CONTINUE READING
