The manipulation of cytokinin contents via Agrobacterium-mediated transformation is an efficient tool for delaying leaf senescence and improving the resistance to environmental stresses. In the present study, cotton transformants harbouring the Agrobacterium tumefaciens isopentenyl transferase (IPT) gene under the control of the promoter of Gossypium(More)
Enterobacter amnigenus (EA76) and Klebsiella pneumoniae (KP76) isolates with multidrug-resistant (MDR) patterns were identified from the same patient in the neurosurgery department of our hospital. An outbreak of MDR K. pneumoniae had also occurred in this department. To characterize the resistance mechanism and molecular epidemiology of these isolates,(More)
The imminent prediction on a group of strong earthquakes that occurred in Xinjiang, China in April 1997 is introduced in detail. The prediction was made on the basis of comprehensive analyses on the results obtained by multiple innovative methods including measurements of crustal stress, observation of infrasonic wave in an ultra low frequency range, and(More)
The effects of short-term osmotic stress [a polyethylene glycol (PEG) treatment] on photosystem II (PS II) of upland and lowland rice seedlings were investigated using chlorophyll (Chl) fluorescence imaging. Spatial heterogeneity in the top fully expanded leaf for all Chl fluorescence parameters was found under stress conditions. After exposure to PEG, a(More)
Recurrent human cytomegalovirus (HCMV) infection during pregnancy could lead to congenital HCMV infection and permanent sequelae. However, knowledge regarding the risk factors associated with recurrent HCMV infection is limited. In the present study, 1,659 paired serum samples from the natural population were collected in Guangxi Province, China, from 2003(More)
