Abstract: The use of an SNP site combination of Litopenaeus vannamei in trait evaluation of mixed-family culture, a probe and a kit. The SNP site combination of Litopenaeus vannamei comprises 1125 SNP sites, wherein the physical positions are determined on the basis of alignment with a reference genome sequence of Litopenaeus vannamei. Also disclosed are a molecular probe for capturing the SNP site combination and a kit comprising the molecular probe. By means of using the SNP site combination for paternity identification, the present invention can achieve the mixed culture of individuals of different families in the early stage, so that the common environmental effect caused by separate family culture in the early stage is effectively reduced, and the accuracy of a trait evaluation result of mixed culture is improved; moreover, the genetic relationship between individuals can be accurately calculated.

Abstract: Methods and compositions to produce insect resistance in plants deploy an engineered glutamate receptor-like protein (GLR3.3) that functions in transmitting wound-induced signals from local to systemic plant organs to trigger synthesis of jasmonic acid, a defense hormone.

Abstract: The present invention discloses primers, probes, a kit and a method for detecting Enterocytozoon hepatopenaei (EHP) pathogens of Litopenaeus vannamei. A PCR reaction system adopted in the method includes: a forward primer having a nucleotide sequence as shown in SEQ ID NO: 1, a reverse primer having a nucleotide sequence as shown in SEQ ID NO: 2, a forward primer having a nucleotide sequence as shown in SEQ ID NO: 4, a reverse primer having a nucleotide sequence as shown in SEQ ID NO: 5, a probe having a nucleotide sequence as shown in SEQ ID NO: 3, and a probe having a nucleotide sequence as shown in SEQ ID NO: 6. The method can perform duplex quantitative fluorescence PCR, an internal reference and a sample to be detected are put in the same reaction, thereby eliminating unstable factors of two reactions and improving the reliability of the result.

Abstract: The invention disclosed here has several key elements: direct probe-on-sensor detection, mesh probe, and mesh reporter. Furthermore, the mesh probe and reporter shall have some physical cross-linking between the polymer backbone(s), either covalently or non-covalently. In combination, this invention enables one to build an ultra-sensitive, low-cost, and highly portable system for molecular detection. Among its many potential applications is a direct detection of nucleic acids in crude lysate in a multiplex format, without the requirements for nucleic acids extraction and amplification. Such an improvement is likely to change the practice of genotyping and gene expression profiling done in a clinic setting. Another application is an ultrasensitive ELIZA assay in a multiplex format.
