Dry rot is a serious potato disease and causes significant losses in China. Research efforts on potato dry rot have been very limited as well as the attempts to characterize the pathogen in the major potato production regions of China. A total of 260 Fusarium isolates were identified in 698 potato tubers collected in six important potato production regions(More)
Over 200 imprinted genes in rice endosperm are known, but the mechanisms modulating their parental allele-specific expression are poorly understood. Here we use three imprinted genes, OsYUCCA11, yellow2-like and ubiquitin hydrolase, to show that differential DNA methylation and tri-methylation of histone H3 lysine 27 (H3K27me3 ) in the promoter and/or gene(More)
