The triphenyl tetrazolium chloride (TTC) reduction assay was evaluated and improved with maize seed (Zea mays cv. Zhengdan958). The reduced TTC in embryo was extracted with three kinds of organic solvents: trichloroacetic acid (TCA)/acetone, ethanol, and acetone. The absorbance spectra of the three extracts were similar, with a maximum at 485 nm. The(More)
The identification of proteins involved in pollen germination and tube growth is important for fundamental studies of fertility and reproduction in flowering plants. We used 2-DE and MALDI-TOF-MS to identify differentially expressed proteins in mature (P0) and 1-h germinated (P1) maize pollen. Among about 470 proteins separated in 2D gels, the abundances of(More)
Pinellia ternata is an important traditional Chinese medicinal plant. The growth of P. ternata is sensitive to high temperatures. To gain a better understanding of heat stress responses in P. ternata, we performed a comparative proteomic analysis. P. ternata seedlings were subjected to a temperature of 38 °C and samples were collected 24 h after treatment.(More)
Tulipa edulis (Miq.) Baker is an important medicinal plant with a variety of anti-cancer properties. The stolon is one of the main asexual reproductive organs of T. edulis and possesses a unique morphology. To explore the molecular mechanism of stolon formation, we performed an RNA-seq analysis of the transcriptomes of stolons at three developmental stages.(More)
How does a proponent’s internal and external social capital impact crowdfunding performance? Based on the theory of social capital, we developed a research model and conducted an econometric analysis using the objective data collected from a Chinese comprehensive crowdfunding platform, ZhongchouNet. Results of an econometric analysis of a sample of 862(More)
Although the importance of the incubator mangers for successful incubation has been widely discussed, there is little evidence on how the incubator mangers leverage various resources contributing to incubation success. The purpose of this paper is to fill this gap by employing the niche manger theory to investigate the extent to which the incubator managers(More)
MicroRNAs (miRNAs) are a class of endogenous, non-coding small RNAs that play an important role in transcriptional and post-transcriptional gene regulation. However, the sequence information and functions of miRNAs are still unexplored in Tulipa edulis. In this study, high-throughput sequencing was used to identify small RNAs in stolon formation stages(More)
