Genetic imprinting refers to the unequal expression of paternal and maternal alleles of a gene in sexually reproducing organisms, including mammals and flowering plants. Although many imprinted genes have been identified in plants, the functions of these imprinted genes have remained largely uninvestigated. We report genome-wide analysis of gene expression,(More)
Hordeum californicum (2n = 2x = 14, HH) is resistant to several wheat diseases and tolerant to lower nitrogen. In this study, a molecular karyotype of H. californicum chromosomes in the Triticum aestivum L. cv. Chinese Spring (CS)-H. californicum amphidiploid (2n = 6x = 56, AABBDDHH) was established. By genomic in situ hybridization (GISH) and multicolor(More)

Seed development in angiosperms requires a 2:1 maternal-to-paternal genome ratio (2m:1p) in the endosperm. When the ratio is disrupted, the seed development is impaired. Rice interploidy crosses result in endosperm failures. Here we report that the defective endosperm was associated with nonadditive expression of small RNAs and protein-coding genes.(More)

Polyploidy occurs in some animals and all flowering plants including important crops such as wheat. The consequences of polyploidy on crops remain elusive partly because their progenitors are unknown. Using two resynthesized wheat allotetraploids Sl Sl AA and AADD with known diploid progenitors, we analyzed mRNA and small RNA transcriptomes in the(More)
Andrias davidianus ranavirus (ADRV) is an emerging viral pathogen that causes severe disease in Chinese giant salamanders, the largest extant amphibian in the world. A fish cell line, Epithelioma papulosum cyprinid (EPC), and a new amphibian cell line, Chinese giant salamander spleen cell (GSSC), were infected with ADRV and observed by light and electron(More)
