Aberrant expression of Aurora A kinase has been frequently implicated in many cancers and contributes to chromosome instability and phosphorylation-mediated ubiquitylation and degradation of p53 for tumorigenesis. Previous studies showed that p53 is degraded by Kaposi's sarcoma herpesvirus (KSHV) encoded latency-associated nuclear antigen (LANA) through its(More)
Apoptosis of virus infected cells can restrict or dampen full blown virus propagation and this can serve as a protective mechanism against virus infection. Consequently, viruses can also delay programmed cell death by enhancing the expression of anti-apoptotic proteins. Human Bcl-2 is expressed on the surface of the mitochondrial membrane and functions as(More)
A study on marker-assisted selection (MAS) for the rf1 gene, which controls pollen sterility in the sorghum A1 cytoplasm, was conducted on the offspring population of two crosses between a maintainer line, BTx-622, and two sweet sorghum lines, BJ-299 and Lunen-2, to test the effectiveness of the MAS method and develop maintainer lines with sweet and juicy(More)
It is difficult to separate object from background using conventional method when the processed image is nonuniform. A new method is proposed in the paper for nonuniform image segmentation: Firstly, grid sample method is performed on initial image to reduce data space and prepare for background estimation. Secondly, Gaussian Low Pass Filter (GLPF) is used(More)
Multi-terminal dc (MTDC) systems based on line-commutated converters have been studied and discussed for more than fifty years. However, no series MTDC system has actually been implemented due to the difficulties in the dc circuit breaker design and the coordination between dc terminals. Recently, the topology with two series converters located in the same(More)
Polygalacturonase-inhibiting proteins (PGIPs) are leucine-rich repeat proteins involved in plant defence. The aim of the current study was to isolate the genomic fragment of PGIP genes in alfalfa (Medicago sativa) and to analyse their sequence variation. Four PGIP genes, namely MsPGIP1, MsPGIP2, MsPGIP3 and MsPGIP4, were discovered using the homology(More)
Common leaf spot (CLS), which is caused by Pseudopeziza medicaginis (Lib.) Sacc., is one of the most serious fungal diseases occurring in autotetraploid alfalfa (Medicago sativa) worldwide. Polygalacturonase-inhibiting proteins (PGIPs) are important candidate genes for disease resistance studies in plants. The association between an alfalfa PGIP gene,(More)
Alligator weed, Alternanthera philoxeroides (Mart.) Grisb, is an amphibious plant with long thick fleshy roots that develop from adventitious roots under drought conditions. To clone differentially-expressed genes from the roots of A. philoxeroides we applied both mRNA differential display and rapid amplification of cDNA ends techniques. A cryptogein-like(More)
Zebra disease, which is caused by Phytophthora nicotianae, is a serious global threat to the main cultivar Agave hybrid No. 11648 (H.11648). This disease requires a long period to obtain anti-P. nicotianae variants by crossbreeding, given that 10 years are needed for this plant to bloom. Therefore, transgenic technology could be useful for the production of(More)
