Background Thermo-sensitive genetic male sterile (TGMS) lines have been widely used in two-line hybrid rice breeding. The two-line hybrids have increased rice yields substantially. However, the effect of environmental temperatures on the fertility conversion is still not fully clear. In this study, we performed a tandem mass tag (TMT)-based proteomic analysis on the anthers of the TGMS line AnnongS-1...
Here we first reported an ultrasensitive fluorescence resonance energy transfer (FRET) biosensor of dichlorvos based on carbon dots and the traditionally colorimetric Ellman’s test. In Ellman’s test, the absorption intensity of 5-thio-2-nitrobenzoic acid anion (TNB−) at 412nm can be used for the determination of acetylcholinesterase (AChE) and its inhibitor. We chose TNB− as energy acceptors to construct...
In electron microscope tomography, the alignment of tilt series images is a major determining factor of resolution in the 3D reconstruction. One method of tilt alignment uses gold beads deposited on or in the specimen as the fiducial markers. This paper describes an "auto pick" software system which can pick markers automatically. It uses a cross correlation function to find out the shift...
From the viewpoints of information theory and system theory, an Information Optimizing Model is proposed based on following rules of language: efficiency, cooperation, distinction, evolution, and reliability. It proposes that language is an optimal encoding system to communicate in the most efficient way. Using this model, a hypothesis is made that when expressing the same meaning using a sentence,...
