Description

The biochip of rice leaf expression sequence label and formation thereof

Technical field

The present invention relates to biological technical field, relate in particular to the biochip of rice leaf expression sequence label and formation thereof.

Background technology

But the sequence of transcriptional expression in the biological gene group (being gene) only accounts for the 3-5% of total sequence, and this part sequence is measured, and will directly cause the discovery of new gene, and obtains information the closest with the industrialization relation in the genome.The eighties in 20th century; the appearance of high-throughout automatic sequencing; make from plasmid complementary DNA (cDNA) (Complementary DNA is called for short cDNA) the many cDNA of library picked at random and clone and determine to become possibility from the dna sequence dna of a hundreds of base at non-carrier two ends.These short dna sequence dnas are called " expressed sequence tag " (Expressed Sequence Tags is called for short ESTs).The notion of expressed sequence tag the earliest by Adams etc. put forward in 1992 (Nature, 355,642-644).Sikela in 1992 and Matsubara (Sikela, et al.Nucleic Acids Res.19,1837-1843; Matsubara, et al.Nature Genetics, 2,173-179), the research strategy of extensive complementary DNA (cDNA) (cDNA) order-checking is proposed at obtaining pressing for of a large amount of messenger RNA(mRNA) (mRNA) sequence.Venter has founded extensive expressed sequence tagging method subsequently.Its essential characteristic is exactly from being carrier with the plasmid, the purpose that structure is finished is organized complementary DNA (cDNA) (Complementary DNA, abbreviation cDNA) in the library, select many cDNA clones at random, utilize the universal primer that carries on the plasmid that DNA sequence is carried out taking turns in the cDNA two ends and measure, the non-carrier from the hundreds of base of 3 ' end or 5 ' end that is obtained is lacked thymus nucleic acid (DNA) sequence.In brief, expressed sequence tag is the short DNA sequence from expressing gene fragment 3 ' end or 5 ' end, represents the part of an expressing gene to transcribe fragment.

Along with the needs and the expressed sequence tag inherent characteristics of development of biology and life science development, in recent years, people had invented biochip.The essence of biochip (Biochips) be exactly on the little substrate of area in an orderly manner dot matrix arranged a series of addressable biological identification molecule in certain position ground (R.J.Lipshutz et al. that are fixed in, Bio Techniques 19 (1995), 442-447; S.P.Fodor et al., Nature364 (1993), 555-556; S.P.Fodor et al., Science 251 (1991), 767-773; A.C.Pease et al., Proc.Natl.Acad.Sci.USA 91 (1994), 5022-5026).Because initial biochip mainly is to be used for determined dna sequence, gene expression profile identify (D.J.Lockhart et al., Nature Biotechnol.14 (1996), 1675-1680) and the detection and analysis (the Feriotto G of gene mutation body, et al., Hum Mutat1999; 13:390-400; Hacia J.G.et al., Nat Genet 1999; 21 (suppl1): 42-7; Hacia JG, etal., Nat Genet 1999; 22:164-7; Nilsson P, et al., Biotechniques 1999; 26:308-16), so be called DNA chip or gene chip again.At present, this technology is extending to non-nucleic acid fields such as immune response, receptors bind, so biochip has exceeded original scope.Nowadays biochip mainly comprises cDNA microarray, oligonucleotide microarray, moving electric microarray and protein chip etc.October nineteen ninety-five Patrick Brown and he the colleague (Bio Techniques, 19 (1995), 442-447) the cDNA microarray technology has been proposed, (Science 1995 for M.Schena; 270 (5235), 467-470) and D.Shalon (Genome Research 1996; 6 (7), 639-645) grade has been made the cDNA array first, and this technology has obtained development at full speed subsequently.The utilization biochip technology carries out the chip utilization hybridization technique and the scanning technique that obtain chip processing, valid data extraction, analyzes and report biochip, can obtain corresponding gene expression profile (Gene expression profiling).At present the DNA chip is employed in a lot of fields with relative characteristics such as simple because of having strong property, handiness, susceptibility, as: determined dna sequence, gene pleiomorphism detect, discovery, vaccine and drug research (M.J.Cunningham et al., the J.Pharmacol.and Toxicol.Methods 2000 of new gene; 44,291-300), (PNAS 2000 for P.M.Schenk, et al. for the resistance research of plant; The fluctuation activity of gene etc. in 97:11655-11660), organic growth, the Harmony research of regulating the gene of cell function, the detection different development stage different tissues.The gene expression data of analyzing gene group mass-producing; observe finally causing the globality of pair cell differentiation; (the Charlie C.Xiang such as genome molecular linkage map that relate to cell proliferation, necrocytosis, energy metabolism, intercellular and intracellular signal transduction, immunoreactive generation, cell migration; et al.; Vaccine; 2001,22 (2002), 22-30).

Carry out gene expression spectrum analysis by biochip to expressed sequence tag and formation thereof, help to find and the newcomer of clone gene family, assignment of genes gene mapping clone, make, cause the mutational site of inherited disease as the chromosomal assignment of genes gene mapping of sequence tagged site (Sequence-TaggedSites is called for short STSs) and gene mapping evaluation, analyzing gene in different tissues expression specificity and set up invention and the pair cell and the organic holistic approach etc. of DNA physical map, new drug.Just because of expressed sequence tag has so superiority, so expressed sequence tag order-checking has become the focus of many genome research mechanism.
