Immature embryos have been used frequently as target tissues in the genetical transformation of wheat. However, obtaining a large number of high quality immature embryos throughout the year is a laborious and delicate process, because of the need to cultivate the plants under controlled conditions. To circumvent this, we have employed mature embryos rather(More)
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)
Stylosanthes sp. is the most important forage legume in tropical areas worldwide. Stylosanthes anthracnose, which is mainly caused by Colletotrichum gloeosporioides, is a globally severe disease in stylo production. Little progress has been made in anthracnose molecular pathogenesis research. In this study, Agrobacterium tumefaciens-mediated transformation(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)
Alternanthera philoxeroides is one of the rather few amphibious plants that can normally grow in both water and upland conditions. Adventitious roots of Alternanthera philoxeroides seedlings will grow long, thick, fleshy during drought stress, which are assumed to improve performance of the plant by more efficient storage and extraction of water from deep(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)
