| Sugar beet (.Beta Vulgaris L.) is the primary of sugar plant. Tap root is the position of store up sugar, so it is important that to research the charge of proteomics with sugar beet tap root growth which in order to understand the molecular mechanism of sugar beet tap root inflation. This paper is research the different express protein which the progress of different sugar beet variety tap root inflation and the indentification proteins was set detailed bioinformatics annotation. The results were as follows:1) This research found 1409 proteins could be relate ro sugar beet tap root growth, is mainly responsible for carbon metabolic, hormone synthetic, protein metabolic, lipid metabolic and so on.2) the energy metabolism in high yield variety was better than that of the rich sugar variety;3) KEGG pawthy analys show that the enzyme aldehyde dehydrogenase, amidase and tryptophan synthase beta chain which take part in the auxin synthesis; the enzyme cytokinin trans-hydroxylase which take part in the cytokinin synthesis; the enzyme gibberellin 2-oxidase which regulate gibberellin; the enzyme S-Adenosylmethionine which take part in the ethylene synthesis; the enzyme phospholipase Al, lipoxygenase, hydroperoxide dehydratase, acyl-CoA oxidase which take part in the jasmonic aid synthesis was different express, proved that sugar beet could regulation inflation via adjust auxin, cytokinin, gibberellin, and jasmonic aid metabolism and signal transduction.4) The enzyme of UDP-glucose 4-epimerase, alpha-1,4-galacturonosyltransferase, hexokinase and so on are different express show that the turgor was increase by accumulate cell wall material in inflation progress, promoting formed cell wall5) The enzyme of Phospholipase D1/2,Phospholipase,diacylglycerol kinase (ATP) are different express show that sugar beet was utilized plasmalemma degradation product as single molecular take part in inflation progress. |
