The complete nucleotide sequences of three sugarcane streak mosaic virus (SCSMV) isolates found in sugarcane plants imported from Japan (JP1, JP2) and Indonesia (ID) into China were determined. Sequence analysis showed that, based on the whole genome sequence and the nucleotide sequences encoding the ten mature proteins, the three SCSMV isolates shared(More)
Sequences of the protein 1 (P1) and coat protein (CP) coding regions of 22 sugarcane streak mosaic virus (SCSMV) isolates were determined. Phylogenetic analysis showed that SCSMV had at least three major lineages, and the lineages seemed to reflect geographical origin. The sudden expansions of the Chinese and Indian subpopulations were supported by(More)
The complete nucleotide sequence of the ssRNA genome of a Chinese GPV isolate of barley yellow dwarf virus (BYDV) was determined. It comprised 5673 nucleotides, and the deduced genome organization resembled that of members of the genus Polerovirus. It was most closely related to cereal yellow dwarf virus-RPV (77% nt identity over the entire genome; coat(More)
Replicating circular RNAs are independent plant pathogens known as viroids, or act to modulate the pathogenesis of plant and animal viruses as their satellite RNAs. The rate of discovery of these subviral pathogens was low over the past 40 years because the classical approaches are technical demanding and time-consuming. We previously described an approach(More)
A simple and fast sap-direct RT-PCR (reverse transcription-polymerase chain reaction) for the rapid detection of 3 viroids of the genus Coleviroid is presented. The templates for cDNA synthesis were obtained directly from the sap of coleus using a pipettor, a common tool in molecular biology laboratories, and 3 coleus blumei viroids (CbVds) were detected(More)
A novel circular DNA virus sequence has been identified through next-generation sequencing and in silico assembly of small RNAs of 21-24 nt from an apple tree grown in China. The virus genome was cloned using two independent approaches and sequenced. With a size of 2932 nt, it showed the same genomic structure and conserved origin of replication reported(More)
The complete nucleotide sequences of two isolates of apple chlorotic leaf spot virus (Z1 and Z3) collected from peach in Henan Province, China, were determined. The genomes of both Z1 and Z3 were found to contain three open reading frames (ORFs). Sequence analysis showed that genomic sequences of Z1 and Z3 isolates shared 67.4%-82.9% and 67.2%-82.6%(More)
Sugarcane streak mosaic virus (SCSMV) causes mosaic and streak symptoms on sugarcane and sorghum crops, and has a broad host range. SCSMV is a member of the genus Poacevirus in the family Potyviridae.Ten SCSMV isolates were collected from sugarcane plants showing mosaic and streaking in Southern China from 2009-2011. Sequence-based phylogenetic and(More)
Glioblastoma multiforme (GBM), the most common brain tumor in adults, is neurologically destructive and has a dismal response to virtually all therapeutic modalities. One phenomenon that can contribute to this complexity is the presence of a relatively small subset of glioma stem cells (GSCs) within the tumor and the activation of pathways that control(More)
This paper presents a new method for the design of distributed controllers that achieve component swapping modularity (CSM) in control systems. Our approach, referred to as the Direct Method, is based on solving a bi-level optimization problem to obtain the distributed controller gains directly. In the previously proposed 3-Step Method, the distributed(More)
