Swimming is detected in 3 transgenic lines the result shows that (Fig. 2)HvERF2.11The expression of gene.
4 turns of embodimentHvERF2.11The identification of Arabidopsis plant moisture-proof
In order to further analyze barley moisture-proof geneHvERF2.11Biological function, which is realized in arabidopsis
Overexpression, and the quasi- phenotypic characteristic from transgenic plant moisture-proof verifies geneHvERF2.11In wet injury stress regulatory
On biological function.Steps are as follows for specific experiment: what in early period, screening was obtainedHvERF2.11What genetic transformation arabidopsis obtained
T3 is for the seed in positive transgenic strain, selecting each 3 strains at random, and arabidopsis wild type seeds (WT) is used in control, 1/
Culture is middle in the controlled environment chamber to cultivate 35 days by seedling replanting into the basin alms bowl equipped with Nutrition Soil to 4 leaf phases on 2MS culture medium.
Transgenic line and wild type are put into water tank, submerging treatment is carried out, after waterflooding 2 weeks, observes transgenic line and wild type
The difference of material moisture-proof, and take the expression analysis of the material progress moisture-proof related gene of different Submergence time sections and correlation raw
The measurement for managing index, after waterflooding, measures the characters such as height of seedling, plant fresh weight, dry weight, the root length of different materials.As a result
Show that the plant height of wild type has dropped 49.09%, and 3 transgenic lines have dropped 30.54%, 27.41%, 32.48% respectively;
Wild type chlorophyll content has dropped 61.56%, and 3 transgenic lines have dropped 29.52%, 35.26%, 31.37% respectively;It is wild
Raw type cauline leaf fresh weight has dropped 65.8%, and 3 transgenic lines have dropped 50%, 19.67%, 17.86% respectively;Wild type cauline leaf is dry
51.01% is had dropped again, and 3 transgenic lines have dropped 46.25%, 40.5%, 16.1% respectively;Wild type root long has dropped
74.87%, 3 transgenic lines have dropped 59.69%, 41.47%, 41.88% respectively;After wet injury processing, wildtype Arabidopsis thaliana
Survival rate is only 27.61%, and the survival rate of transgenic arabidopsis is up to 78% or more (Fig. 3), shows to be overexpressedHvERF2.11Base
Because clearly enhancing the moisture-proof of arabidopsis.
Control and wild type under wet injury treatment conditions and transgenic arabidopsis activities of antioxidant enzymes (SOD, CAT, POD), second
The variation of alcohol dehydrogenase (ADH) activity and proline content as shown in figure 4, under normal growing conditions, transgenic line with it is wild
Type is in terms of physiological-biochemical level without notable difference;Wet injury is handled 3 days, and antioxidase and alcohol dehydrogenase in wild type and turn
Obviously increased in gene strain, wet injury is handled 6 days, increase up to maximum value, transgenic line increasing degree be substantially higher in
Non-transgenic system;After wet injury is handled 9 days, antioxidase and alcohol dehydrogenase activity begin to decline (Fig. 4 A, B, C, D).It is wet
Evil causes the proline content of wild type and transgenic line to obviously increase, but the increasing degree of wild type will be significantly greater than and turn
Gene strain (Fig. 4 E).Show that wet injury stress is lower to be overexpressedHvERF2.11Antioxidant Enzyme Systems are clear in genes amplification arabidopsis
Except the efficiency of harmful substance, the resistance that arabidopsis coerces wet injury is improved.
For identificationHvERF2.11The regulating effect of gene pairs wet injury stress response related gene, using qRT-PCR to turning base
Because gene relevant to activities of antioxidant enzymes, glycolysis and ethylene synthase in arabidopsis and wild type (AtSOD1,AtCAT1,AtPOD1,AtADH1,AtPDC11,AtACO1) carry out gene expression analysis.As shown in figure 5, under normal growing conditions,AtPOD1WithAtACO1Differential expression of the gene between wild type and transgenic arabidopsis reaches the level of signifiance, remaining gene does not have
Apparent differential expression;After wet injury stress, the expression of 6 genes is aobvious in wildtype Arabidopsis thaliana and transgenic arabidopsis
Up-regulated expression is write, and the ascensional range in transgenic arabidopsis is bigger;Wet injury is handled 3 days,AtSOD1、AtPOD1WithAtACO1
Gene expression dose reaches maximum value, and processing starts to gradually decrease (Fig. 5 A, C, F) after 6 days and 9 days;Wet injury is handled 3 days,AtCAT1、AtADH1WithAtPDC1The gene expression dose rate of climb is slower, and after wet injury is handled 6 days, gene expression dose reaches
Highest, wet injury are handled 9 days, and expression starts to reduce (Fig. 5 B, D, E).ShowHvERF2.11The controllable antioxygen of gene
Change enzyme, fermentation, gene relevant to wet injury stress in ethylene synthase approach, enhances the resistance that arabidopsis coerces wet injury.
