Abstract: A set of primers and probes for simultaneous detection of Cymbidium mosaic virus (CymMV), Odontoglossum ringspot virus (ORSV), and Cymbidium ringspot virus (CymRSV) and a method for detecting CymMV, ORSV, and CymRSV, along with a method for their detection, are disclosed. The method involves designing multiplex real-time quantitative PCR detection primers and probes for CymMV, ORSV, and CymRSV and applying these primers and probes to the real-time quantitative PCR simultaneous detection of CymMV, ORSV, and CymRSV. It allows for faster detection of CymMV, ORSV, and CymRSV, taking only one-third of the time compared to uniplex real-time quantitative PCR technology, thereby reducing testing costs by approximately ? to ½ for each sample. The primers and probes are highly specific and sensitive, with a sensitivity as low as 1 to 10 copies. It provides an efficient and feasible detection method for early detection and prevention of CymMV, ORSV, and CymRSV.

The method includes the following steps: conducting virus detection on a Dianthus caryophyllus explant, and inoculating the explant into an induction medium for induction culture; after the explant germinates, cutting buds, and determining whether a virus-free treatment is required according to a virus detection result, and continuing cultivating the buds; after cultivating to obtain cluster buds, inoculating the cluster buds into an expanding propagation medium for expanding propagation, and conducting the virus detection to eliminate a virus-carrying material; conducting expanding propagation on a virus-free material to a certain base, and transferring the virus-free material to a rooting medium for rooting culture.

Abstract: Disclosed are a M-cell targeting and pH-responsive starch-based carrier material, and a preparation method and application thereof. The starch-based carrier material has a molecular structure as follows, a molecular weight of 7.04×104 to 2.11×106 g/mol, a degree of substitution of carboxymethyl groups of 0.04 to 0.28, and a grafting amount of targeting peptide GRGDS of 0.01% to 1.12% (calculated based on the content of N). The material is not dissolved in water when protonated at pH (pH=1.2) of the stomach, and is slowly dissolved in water when deprotonated at pH (pH=6.8) of the small intestine, therefore it has good responsiveness to pH of the gastrointestinal tract. The material can efficiently encapsulate a positively charged active substance by means of electrostatic interaction, therefore it can protect the active substances from being destroyed and inactivated in the gastrointestinal tract.
