Interstitial telomeric repeats (ITRs) were reported in a number of animal and plant species. Most ITRs are organized as short tandem arrays and are likely evolutionary relics derived from chromosomal rearrangements and DNA repairs. However, megabase-sized ITR arrays were reported in Solanum species. Here, we report a fluorescence in situ hybridization(More)
China is the world's leading producer of potatoes, growing 22% of all potatoes. Production continues to rise, owing to increases in both land devoted to potato production and yield per hectare. Most potato production occurs in the northern and southwest regions of the country. The processing of coarse starch is the most important component of the potato(More)
A large number of quantitative trait loci (QTL) for resistance to late blight of potato have been reported with a “conventional” method in which each phenotypic trait reflects the cumulative genetic effects for the duration of the disease process. However, as genes controlling response to disease may have unique contributions with specific temporal(More)
To solve the problem of over-reliance on a priori assumptions of the parametric methods for finite mixture models and the problem that monic Chebyshev orthogonal polynomials can only process the gray images, a segmentation method of mixture models of multivariate Chebyshev orthogonal polynomials for color image was proposed in this paper. First, the(More)
e13086 Background: Gene therapy is a promising therapeutic approach for cancer. Targeted expression of desired therapeutic proteins within the tumor is the best approach to reduce toxicity and improve survival. This study was to establish a more effective and less toxic gene therapy of cancer. METHODS Combined gene therapy strategy with recombinant(More)
The somatic hybrids were derived previously from protoplast fusion between Solanum tuberosum and S. chacoense to gain the bacterial wilt resistance from the wild species. The genome components analysis in the present research was to clarify the nuclear and cytoplasmic composition of the hybrids, to explore the molecular markers associated with the(More)
BACKGROUND To evaluate the contribution of chemotherapy for patients with locoregionally advanced nasopharyngeal carcinoma (NPC) treated by intensity modulated radiotherapy (IMRT) and to identify the optimal combination treatment strategy. PATIENTS AND METHODS Between 2006 and 2010, 276 patients with stage II-IVb NPC were treated by IMRT alone or IMRT(More)
Wild potato contains about 100 species that are native to the Americas from the southwestern United States to central Chile and adjacent Argentina, Uruguay, Paraguay, and southern Brazil. We report the occurrence of naturalized populations of the wild potato Solanum chacoense in seven sites in southern Australia, eastern China, England, New Zealand, the(More)
Cold-induced sweetening (CIS) is a crucial factor influencing the processing quality of potato tubers. To better understand the molecular events of potato CIS and different CIS-sensitivity among various potato species, a suppression subtractive hybridization library and cDNA microarray gene filters were developed. A total of 188 genes were found to be(More)
The known functions of telomerase in tumor cells include replenishing telomeric DNA and maintaining cell immortality. We have previously shown the existence of a negative correlation between human telomerase reverse transcriptase (hTERT) and radiosensitivity in tumor cells. Here we set out to elucidate the molecular mechanisms underlying regulation by(More)
