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.

Web2 days ago · In TOC1, three QTLs (qOC-1-1, qOC-1-2 and qOC-1-3) distributed on chromosome 3, 5 and 9.The QTL, qOC-1-3, with the largest effect (30.84% of the phenotypic variation) was located on chromosome 9.The parental KB717001 allele at this locus had an additive effect of 0.24% for increased oil content. The second QTL qOC-1-2 … 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. WebThe germinal cells are diploid and act as meiocytes, which undergo meiosis to produce haploid gametes. Thus, meiocytes have diploid ( 2 n ) number of chromosomes, same as the somatic cells.
