Description
Technical field
The invention belongs to the domestic animal gene engineering technology field, be specifically related to molecule marker CSRP3 clone and application a kind of and the pig muscle correlation of attributes.
Background technology
Pork is the main source of China people animal proteinum.Many decades is in the time in the past, and along with the introduction of external high lean ratio and fast speed of growth boar, the demand in market has quantitatively been satisfied in China's pork production gradually.But, to lean ratio and the speed of growth excessively select and the boar cultivated aspect the meat quality not as good as the place of china pig.Along with the change of growth in the living standard and consumption idea, the lean meat of all good and safety of color, nutrition more and more is subjected to human consumer's favor.Therefore, the improvement of meat quality has become the important goal of current high-quality pig breeding work, and the searching of related molecular marker is the important means of realizing this goal.
Meat quality is a comprehensive proterties, usually by muscle pH value, intramuscular fat content, marble grain, be that indexs such as waterpower, shearing force, drip loss, yellowish pink, tender degree, diameter of muscle fiber are measured.Be not independently between these indexs, but contact each other determine final meat quality jointly.Molecular marker screening for complex characters such as pig muscle qualities adopts the strategy of QTL scanning in conjunction with the candidate gene clone usually, promptly at first make up a resource colony, measure the relevant various indexs of meat quality, and carry out complete genomic QTL scanning, in the QTL zone, adopt function candidate gene method or position clone's the corresponding mark of Policy Filtering again.According to PigQTLdb (
Http:// www.animalgenome.org/QTLdb/pig.html) statistic data, the QTL relevant with meat quality is above 1000, almost be distributed on all karyomit(e) of pig, wherein No. 2, No. 4, No. 5, No. 6, No. 7, No. 11, No. 14, No. 15 with No. 17 karyomit(e) on the QTL relevant with meat quality the most intensive.
Although a large amount of QTLs relevant with meat quality are positioned, the gene and the molecule marking research that influence meat quality but lag far behind this.At present, the major gene of having identified that influences meat quality comprises both at home and abroad: (1) RYR1 gene (Fujii, J etc., Identification of amutation in porcine ryanodine raceptor associated with malignant hyperthermia.Science, 1991,253:448-451), the C1843T missense mutation that studies show that this gene be cause pig to produce stress syndromes and the meat quality main reasons for decrease takes place.(2) PRKAG3 gene (Milan, D etc., A mutation in PRKAG3 associated with excess glycogen content inpig skeletal muscle.Science, 2000,288:1248-1251), a sudden change that studies show that this gene is to cause hampshire to produce the major cause of " sour meat ".The reason of these two genes is suddenlyd change and is all identified, and has obtained good molecular biology explanation, therefore has been used as the breeding practice that molecule marker is used for eliminating " fluothane " sensitive gene and " sour meat " gene.
Although and some other gene relevant with meat quality is much to seek the reason sudden change now, but find that but there are significant correlation in its polymorphic and meat quality proterties, these genes comprise: (1) CAST gene (Ciobanu, D C etc., New alleles in calpastatin gene areassociated with meat quality traits in pigs.Joumal of Animal Science, 2004,82:2829-2839), studies show that there is significant correlation in a plurality of meat proterties such as a plurality of SNP of this gene and the tender degree of muscle.(2) H-FABP gene (Gerbens, F etc., The effectof adipocyte and heart fatty acid-binding protein genes on intramuscular fat and backfat content inMeishan crossbred pigs.Joumal of Animal Science, 2000,78:552-559), studies show that there are significant correlation in the sudden change of this gene and intramuscular fat content.(3) CA3 gene (Wang, H L etc., Molecular characterization and association analysisof porcine CA3.Cytogenetic and Genome Research, 2006,115:129-133), studies show that there are utmost point significant correlation in the sudden change of this gene and intramuscular fat content and leg stern ratio.Compare with localized QTL, identified the reason sudden change or found to exist relevant number gene to be nowhere near, illustrate that a large amount of genes relevant with meat quality remains further evaluation.
There are a large amount of QTLs relevant with meat quality in pig 2p14-17 chromosome segment, and the CSRP3 gene is an important function candidate gene that is positioned at this zone.(cysteine and glycine-rich protein 3, CSRP3) gene are called Muscle LIM protein (MLP) or cardiac LIM protein (CLP) again to CSRP3, are one of coding LIM domain protein CSRP gene family members.Studies show that mouse CSRP3 gene only expresses in voluntary muscle, and its expression is consistent with the flesh atomization, be a myogenetic positive regulating factor (Arber, S. etc., MuscleLIM protein, a novel essential regulator of myogenesis, promotes myogenic differentiation, Cell, 1994,79:221-31).The CSRP3 knock out mice shows the form and the Clinical symptoms (Arber of hyperplasia myocarditis and heart function disorder, S. etc., MLP-deficient mice exhibit a disruption of cardiac cytoarchitectural organization, dilated cardiomyopathy, andheart failure, Cell, 1997,88:393-403; Geier, C etc., Mutations in the human muscle LIM protein gene in familieswith hypertrophic cardiomyopathy, Circulation, 2003,107:1390-1395).Immunohistochemical analysis shows the expression of MLP albumen composition in the rat slow muscle, and low expression in fast muscle, and MLP is converted to up-regulated expression (Willmann in the slow type skeletal muscle protein process at fast type skeletal muscle albumen, R etc., Muscle LIM protein is upregulated in fast skeletal muscle during transition towardslower phenotypes, Am J Physiol Cell Physiol, 2001,280:C273-9); Other there are some researches show, CSRP3 gene encoding production MLP can be by a kind of physics mode and basic helix-loop-helix (bHLH) transcription factor of muscle tissue have an effect, this effect has the specificity of height, be that MLP is not with non-muscle-derived bHLH albumen (as E12 and E47) or become flesh enhancement factor-2 (the MEF2) (Kong that has an effect, Y etc., Muscle LIM protein promotes myogenesis by enhancing the activity of MyoD, Mol Cell Biol, 1997,17:4750-60).MLP may be with the form promotion muscle-derived bHLH albumen of the co-activation factor and the (Kong that combines of specific DNA controlling element, Y etc., Muscle LIM protein promotes myogenesis by enhancing the activity of MyoD, Mol Cell Biol, 1997,17:4750-60).This shows that the CSRP3 gene has important positive control in voluntary muscle is grown, and may participate in the adjusting of muscle fiber types and distribution.
