The role of SYN1 in early Arabidopsis meiosis
… Cytological analysis of syn1\(^{-/-}\) has shown chromosome fragmentation at metaphase I. To determine the basis of chromosome fragmentation in the syn1\(^{-/-}\), three double mutants were constructed. I have demonstrated that chromosome fragmentation in syn1 is AtSPO11-1-dependent. Moreover, I …

Identification and Characterization of Factors Involved in Sodium Selenite Toxicity
… as a molecular read out, I took advantage of a chromosome fragmentation assay to detect SeL-mediated DNA damage. A new factor involved in SeL resistance is the high mobility group (HMG) protein Hmo1. As Hmo1 has been shown to interact with Topoisomerase 2 (Top2) to organize chromatin …

Study of mechanism of genetic death in Escherichia coli in response to A) dTTP starvation and B) combination of temperature sensitive defects in replication initiation and double strand break repair
… a possible mechanism of replication-independent chromosome fragmentation observed in hyper-TLD mutants. The fourth chapter is a compilation of TEM images of E. coli cells undergoing TLD. As a comparison, we have also imaged E. coli cells treated with nalidixic acid, which kills the cells by …
