	Abstract:In this study, an antioxidant gene was isolated and cloned from the widespread plant Capsella bursa-pastoris. The antioxidant gene was homologous highly to the Arabidopsis ATPER1 gene, and was named as CbPER1. We deduced the amino acid sequence of CbPER1 protein, and used it to conduct a phylogenetic tree combining with 1-Cys Prxs (1-cysteine peroxiredoxins) from other plants for estimating the relationships. Using RT-PCR, we analyzed the expression of CbPER1 in different organs and embryonic stages. CbPER1 was extensively expressed in seeds, especially middle and later seeds. Besides, CbPER1 rarely responded to heat stress, cold stress, and ABA treatment in young leaves. Similarly, CbPER1 was not induced to express in young flowers when C. bursa-pastoris plants were treated with ABA. CbPER1 showed down-regulation in dormant embryos after GA treatment. Furthermore, the transcriptional level of CbPER1 in C. bursa-pastoris was compared to that of the Arabidopsis AtPER1, and both shared similar gene expression profiles. Our findings suggest that the CbPER1 genes play significant roles in seed maturation, dormancy, and germination, not in the response to abiotic stresses in C. bursa-pastoris.

	Abstract:Polyploidization is known to accompany altered DNA methylation in higher plants, which plays an important role in gene expression regulation and maintaining genome stability. While the characteristics of DNA methylation in different polyploid plants are still to be elucidated. Here, status of genomic DNA methylation in a series of diploid, triploid, tetraploid annual herbaceous plants (watermelon and Salvia) and woody perennials (pear, poplar and loquat) were explored by methylation specific amplified polymorphism (MSAP) analysis. The results indicated that levels of DNA methylation in triploid watermelon and Salvia were lower than their diploid parents. In triploid poplar and pear, higher levels of DNA methylation were detected, and no significant difference was observed between triploid and tetraploid in all tested materials. Further data analysis suggested that about half of the total detected sites underwent changes of DNA methylation patterns in triploid watermelons and Salvia, as well as an obvious trend towards demethylation. However, the changes of DNA methylation patterns in three triploid woody perennials were only 17.54%~33.40%. This implied that the characteristics of DNA methylation are significantly different during the polyploidization of different plant species. Furthermore, the results suggested that the level of DNA methylation was non-linearly related to the ploidy level, and triploid plants displayed more interesting DNA methylation status. The characteristics and possible functions of DNA methylation in different ploidy series are further discussed.
