Analysis of cell cycle surveillance mechanisms in meiosis
… progression. Through their action, aberrant meiocytes are delayed in their meiotic progression to facilitate repair of meiotic DSBs, or are culled through programmed cell death, thereby protecting the germline from aneuploidies that could lead to spontaneous abortions, birth defects and …

The role of SYN1 in early Arabidopsis meiosis
… by analysing Atdmc1\(^{-/-}\)/syn1\(^{-/-}\) meiocytes. To investigate this further, immunolocalization studies in wild-type and syn1\(^{-/-}\) were conducted. Distribution of ASY1 and AtZYP1 was affected in syn1\(^{-/-}\). Both proteins appeared as aggregates, developing into an abnormal …

Identifying natural modifiers of meiotic crossover frequency in Arabidopsis thaliana
… for genes that are predominantly expressed in meiocytes, and several gene ontology terms pertaining to protein modification and meiotic processes. These results further demonstrate the existence of genetic modifiers of crossover frequency in natural populations of A. thaliana, and the …

Reproductive and somatic functions of RAD51A and BRCA2 genes in maize
… also investigated in male zygotene and pachytene meiocytes. ZYP1, a protein involved in pairing homologous chromosomes, was localized in these cells. As predicted, rad51a1/rad51a2 and brca2 mutants had impaired ZYP1 axis formation compared to wild type; ZYP1 co-localized with DNA but with a more …

Multiploidia em calos provenientes de anteras de tomate
A cultura de anteras tem sido aplicada em tomate como tentativa à indução de calogênese seguida da regeneração de plantas haplóides e duplo-haplóides. Por meio desta técnica, linhas homozigóticas podem ser obtidas, o que tem sido considerado relevante para programas de melhoramento e técnicas …
