The invention is directed to methods for highly-multiplexed simultaneous detection of nucleic acids encoding paired adaptive immune heterodimers from a large number of biological samples containing lymphocytes of interest. Methods of the invention comprise performing a single pairing assay on a pool of source samples to determine nucleic acids encoding paired cognate receptor heterodimer chains in the combined pool. Separately, single-locus, high-throughput sequencing is performed on each individual sample to determine the plurality of sequences encoding one of the two receptor polypeptide chains. Pairs of cognate sequences determined in the pooled sample may then be mapped back to a single source sample by comparing the expression patterns of the single-locus sequences.

Transgenic plants are provided comprising a plurality of transgenes comprised in a single locus. In certain aspects, 7 or more transgenes may be expressed from a first locus. Methods are provided for transformation of plant cells with a plurality of transgenes. Also provided are methods for expressing and enhancing the expression of one or more transgenes in a plant.

The cauliflower (Brassica oleracea L. var. botrytis) Or gene is a semi-dominant, single-locus mutation. It induces the accumulation of high levels of beta-carotene in various tissues that are normally devoid of carotenoids, turning them orange. Using a map-based cloning strategy, we identified a single gene representing Or and successfully verified its identity by functional complementation in the wild type cauliflower. The Or gene encodes a plastid membrane protein containing the DnaJ zinc figure domain. A likely gain-of-function mutation from a 4.3-kb retrotransposon insertion in the Or allele confers the orange phenotype in the mutant. Southern blot analysis revealed that Or is a single-copy sequence in the cauliflower genome. High level of expression of the Or gene and the protein was found in very young leaves, curds, and flowers at comparable abundance between wild type and the Or mutant. Or likely functions in regulating the differentiation of some non-photosynthetic plastids into chromoplasts, which provide the deposition “sink” for carotenoid accumulation. Successful demonstration of Or in conferring carotenoid accumulation in potato tubers indicates its potential use to improve the nutritional value in staple crops.

The invention discloses a transgenic vector of salivary gland tissue specific expression foreign protein and a construction method thereof; the expression vector is constructed by inserting a recombinant fusion gene constructed by glucanase gene, xylanase gene, and phytase gene into a parotid gland-specific transgenic vector; the vector is introduced into pig genome, and transgenic pigs is produced by a somatic cell nucleus transplant technique. The transgenic vector of the invention has hydrolytic action on glucanase in barley raw materials, xylanase in wheat and corn, and phytase in vegetable feed; the pig salivary gland is used as a reactor to realize secretion for the whole life; the addition of the enzyme preparations into feed is replaced permanently, which gives better play to the enzymes; the expression vector of the invention has a piggyback transposon, which greatly increases the transgenosis efficiency, changes the transgenic integration model of common plasmid serial recombination into single locus single copy integration, and thus better simulates the internal environment of biological genes.

The present invention is a novel protocol for the massively parallel production of improved MIPs. The molecular improvements to the MIP cover the manufacturing of the probes, the workflow, the addition of unique sequence elements which connote sample specificity, and a sequence tag which uniquely identifies a specific molecule present in the initial sample population. Lastly, this invention also is combined with an empirical optimization strategy that overcomes issues of both locus representation and allelic bias. This improved technique is scalable and can be utilized to amplify targets comprised of a single locus' amplicon up to targeting more than 1 million loci.
