Characterization of Microsatellite Markers and Their Application to Genetic Diversity Analysis of <i>Brachypodium sylvaticum</i>var. <i>breviglume</i>from Yunnan, China

American Journal of Plant Sciences 2013年第7期4卷 1427-1434页

Southwestern China is abundant in a large species diversity of grasses and Brachypodium sylvaticum var. breviglume is unquestionably appropriate to serve as an ideal model to investigate the adaptation, evolution and diversification of grasses in this region. In this study, a total of 37 microsatellite markers were screened and genetic variation was estimated for 100 individuals from the five natural populations of the species. Our results showed that seven of them were polymorphic for the five studied populations, while the other thirty were monomorphic. These seven SSR loci exhibited a high level of genetic diversity among populations, i.e. allele number varied from 5 to 24, with an average of 13.29;expected heterozygosity (He) ranged from 0.439 to 0.561, with an average of 0.488;percentage of polymorphic loci (PPL) ranged from 85.71% to 100%, with an average of 97. 14%. The FCA and UPGMA analyses revealed that the five populations were divided into three clusters. Our results indicate that these newly characterized SSR markers are useful for the exploration of genetic diversity and evolutionary history of the B. sylvaticum var. breviglume populations in Yunnan, China.

The reprogramming of parental epigenomes in human early embryos remains elusive. To what extent the characteristics of parental epigenomes are conserved between humans and mice is currently unknown. Here,we mapped parental haploid epigenomes using human parthenogenetic and androgenetic embryos. Human embryos have a larger portion of genome with parentally specific epigenetic states than mouse *** allelic patterns of epigenetic states for orthologous regions are not conserved between humans and mice. Nevertheless, it is conserved that maternal DNA methylation and paternal H3K27me3 are associated with the repression of two alleles in humans and mice. In addition, for DNA-methylation-dependent imprinting, we report 19 novel imprinted genes and their associated germline differentially methylated regions. Unlike in mice, H3K27me3-dependent imprinting is not observed in human early ***, allele-specific epigenomic reprogramming is different in humans and mice.
