WebNov 17, 1997 · In normal maize meiocytes the chromosomes tend to move at roughly the same speed during anaphase (Fig. 1). This contrasts with the rates of neocentromere movement, which are highly variable. Rates of neocentromere movement as fast as 1.4 μm/min and as slow as 0.91 μm/min were documented in a single Ab10 meiocyte. WebI have been working on plant biology research for 7+ years. During my Phd, I worked on meiotic gene clone and functional analysis in maize, I identified 3 maize meiotic genes (ZmRAD51C, ZmMTOPVIB and ACOZ1) and uncovered their function in meiotic DSB formation, DSB repair, crossover formation and chromosome structure regulation.
