P element transposition in Drosophila melanogaster: an analysis of sister-chromatid pairs and the formation of intragenic secondary insertions during meiosis
Article Abstract:
A meiotic mutant that induces high frequency equational nondisjunction, mei-S332, was used to study the alterations in transposition of Drosophila melanogaster P elements at meiosis. Results showed that P element transposition and excision occcur at relatively high frequencies during meiosis. Moreover, secondary insertions of an X-linked ry+ transposon during the meiotic cycle of males in or near the parental copy are generated in a large number of exceptional chromosomes.

SWITCH1(SWI1): a novel protein required for the establishment of sister chromatid cohesion and for bivalent formation at meiosis
Article Abstract:
A new gene, SWI1, has been characterized in study of Arabidopsis thaliana. It is involved in sister chromatid cohesion in both male and female meiosis in the plant. A novel protein, SWITCH1 (SWI1), necessary for the establishment of sister chromatid cohesion and for bivalent formation in meiosis has been found.

Meiotic crossover number and distribution are regulated by a dosage compensation protein that resembles a condensin subunit
Article Abstract:
The regulation of meiotic crossover number and distribution processes by a dosage compensation protein resembling a condensin subunit is discussed. Caenorhabditis elegans protein DPY-28 is responsible for controlling both the processes.
