Abstract
The invention discloses for detecting ginseng bundle trunk cell specific gene PgWOX4 and its detection method and application.Specific gene PgWOX4 disclosed by the invention for detecting ginseng bundle trunk cell can be used for marking ginseng bundle trunk cell.The invention also discloses a kind of detection ginseng bundle trunk cell area or the methods of position.The present invention has filled up the blank of non-mode plant stem cell detection field, provides a set of feasible detection scheme for the positioning of non-mode plant stem cell, has extraordinary research potential and application prospect.
Description
Technical field
The present invention relates to field of biotechnology, and in particular to for detecting the specific gene of ginseng bundle trunk cell
PgWOX4 and its detection method and application.
Background technique
Ginseng (Panax ginseng C.A.Mey.) is Araliaceae perennial herb plant, has 5000 in China
The medication history of many years has effects that reinforce vital energy, veins takes off admittedly, reinforce the spleen to benefit the lung, production of sperm blood-nourishing, tranquilize the mind and promote the intelligence, is listed in
" top grade " of Shennong's Herbal, enjoys the good reputation of " King of Herbs ".Under natural conditions, wild ginseng has extremely strong reparation energy
Power can resist the erosion of pathogen and herbivore.It is extremely strong extensive that ginseng " Ding change " phenomenon shows that ginseng stem cell has
Reactivation power and regeneration potential.Wherein, ginseng bundle trunk cell is to the development of ginseng leaf, the growth of stem, the overstriking of root and damage
It repairs significant, however how to detect ginseng bundle trunk cell there is not been reported.
RNA hybridization in situ technique is a kind of using the known RNA of specific markers as phase in probe, with cell or tissue slice
The genetic fragment answered combines (hybridization), and the hybrid (hybrids) of formation is through chromogenic reaction, to carry out essence to specific gene

Two, whole mount in situ hybridization
Fresh leaves of panax ginseng, the aerial stem of plant, root (taking the transverse section at the lower 1.0-1.2cm of reed head) are acquired as sample material
Material detects ginseng bundle trunk cell with the rna probe of the PgWOX4 genetic fragment of step 1 preparation.Specific steps
It is as follows:
1, specimen material is put into fixer (4%PFA solution) and is fixed, vacuum suction is extremely in fixer for material
Until bubble-free generates.After the completion of pumping, material is sunken to bottom, and the 4%PFA/PBST solution renewed is (containing 0.1%
Tween20), after vacuumizing, 4 DEG C overnight.
2, after completing step 1, using PBST solution and 4%PFA solution replacement, so that material is suspended in PBST solution.
Then (20% ethyl alcohol/PBST, 20min are replaced with ethyl alcohol and PBST solution gradient;40% ethyl alcohol/PBST, 20min;60% second
Alcohol/PBST, 20min;80% ethyl alcohol/PBST, 20min;100% ethyl alcohol, 20min, 2 times).It is set again with ethyl alcohol to dimethylbenzene gradient
Change (ethyl alcohol: dimethylbenzene=2:1,30min;Ethyl alcohol: dimethylbenzene=1:1,30min;Ethyl alcohol: dimethylbenzene=1:2,30min;Pure two
Toluene, 1h).Finally (dimethylbenzene: ethyl alcohol=2:1,30min is replaced with dimethylbenzene to ethanol gradient again;Dimethylbenzene: ethyl alcohol=1:
1,30min;Dimethylbenzene: ethyl alcohol=1:2,30min;Straight alcohol, 30min, 3 times).
3, complete step 2 after, material is put in prehybridization solution 1,55 DEG C incubations 5-10 hours, then use Proteinase K exist
30min is digested at 37 DEG C, then is reacted with 5% glycine/PBST processing 5min with terminating.Material is finally put in prehybridization solution
In 2,55 DEG C hybridization 2-4 hours.
4, after completing step 3, the tRNA that 1mg/mL is added into prehybridization solution 2 (is purchased from Roche, article No. is
1093274910) and the PgWOX4 denatured probe of 1 μ g (the positive probe and reversed probe that prepare in step 1), hybridization is for 24 hours.
5, after completing step 4, unbonded probe is washed off, is closed at room temperature using 5%BSA/PBST 1 hour.Then
In the ratio of 1:2000, DIG antibody (being purchased from Roche, article No. 1093274910) is added in confining liquid, room temperature reaction 16 is small
When.Chromogenic reaction is carried out with NBT/BCIP again, is protected from light 2-6 hours, is terminated and is reacted using 4%PFA.Finally use PBST solution
Ginseng bundle trunk cell is detected using body formula mirror and microscope after washing.
As a result as shown in Fig. 2, as can be seen from the figure: the position of blue markings is leaves of panax ginseng bundle trunk cell
(i.e. blade vascular bundle forming layer), cauline bundle stem cell (i.e. ground cauline bundle forming layer), root bundle trunk cell (i.e. root
Vascular bundle forming layer and phellogen), the reversed rna probe of PgWOX4 gene is tieed up in leaves of panax ginseng bundle trunk cell, stem
Hybridize in tube bank stem cell and root bundle trunk cell with the mRNA of PgWOX4 gene, illustrates PgWOX4 gene mainly in folium panacis japonici cum caule
It is expressed in piece bundle trunk cell, cauline bundle stem cell and root bundle trunk cell, and the positive rna probe of PgWOX4 gene
It cannot hybridize.The above results show: PgWOX4 gene can be used as the marker gene of ginseng bundle trunk cell, and based on this
The whole mount in situ hybridization method of the reversed rna probe of the PgWOX4 gene of invention can effectively detect ginseng bundle trunk cell
Position, and can intuitively, clearly observe ginseng bundle trunk cell.
