Amount gradually rises.Beta carotene treatment group is compared with blank control group, and the aragonite content of control group is less than beta carotene processing
Group (Fig. 3).
The SEM observation of 3.3 Margaritas layer is (as shown in figures 4-9):
From Fig. 4-Fig. 9, when beta carotene handles 30d, the chip of Margarita layer is in subcircular, size
It is more uniform, arrange more neat, surface is more smooth, whole chip is in sheet arrangement (Fig. 4).When beta carotene handles 60d,
Chip is changed into hexagon, corner angle gradually clearly demarcated and thickness increase (Fig. 5) from subcircular.It is when the processing time of beta carotene
During 90d, Margarita layer crystallization is best, and chip is in regular hexagon, and shape is clear, clear-cut, edge is straight, thick and heavy full
It is full;From exposed secondary top layer, secondary top layer is still constituted for regular hexagon chip, the very even uniform of arrangement, extexine
Hexagon chip nucleation is on the hexagon chip on secondary top layer, and chip is arranged layer by layer, close structure, and lamination substantially (is schemed
6).When beta carotene handles 150d, 180d, with the extension of time, the chip of Margarita layer is gradually by positive six side
Deformation it is irregular, there is round bar shape, subcircular, graininess, crystallization corpusculum not of uniform size, the no longer smooth light of pearl layer surface
Sliding, lamination is not obvious, and CaCO3The organic substrate of wafer periphery gradually increases (Fig. 8, Fig. 9).
For blank control group, the chip of Margarita layer occur in that first the crystallization of similar calcite rhombus and
Irregular particle (Fig. 4).With the extension of time, chip gradually becomes the hexagon of rule, the chip architecture formed during 90d
Preferably, obvious surface smoother (Fig. 6) is layered, coarse irregular (Fig. 8, Fig. 9) that then chip lamella becomes again.With β-Hu Luo
Bu Su treatment groups are compared, and the wafer quality of whole period Triangle ID sail freshwater mussel nacre is below beta carotene treatment group.
4th, conclusion:
The influence immune to the Pearl-sac Cells of Freshwater Pearl Mussel Hyriopsis Cumingiilea formation phase of 4.1 beta carotenes:
Hydriopsis cumingii is low aquatic invertebrate, lacks specific immune system, and its nospecific immunity is present
A certain degree of inducibility.Catalase (CAT) and peroxidase (POD) are widely distributed in nature, and it can be with
Reflect the state of body Radical Metabolism, and it is closely related with the disease resistance of animals and plants, it is enzymatic protective system in animal and plant cells
In member.Animals and plants can produce substantial amounts of H during metabolism2O2、O2 -, these materials on the one hand can kill bacterium,
Make body from the H of the infringement of bacterium, on the other hand excess2O2、O2 -Body cell can be made to occur Peroxidative damage.CAT enzymes
Main function is exactly to be catalyzed H2O2It is decomposed into H2O and O2, prevent that active oxygen radical from starting Lipid peroxidation metabolism or film fat takes off ester and made
With;POD enzymes are exactly to utilize intracellular harmful metabolite H2O2、O2 -Deng by be equally produce in metabolic process phenol, amine,
The material oxidation Decomposition such as alcohol, aldehyde, to mitigate intracellular toxicity.
In this research, research object is 1 age hydriopsis cumingii, and now hydriopsis cumingii just plants piece, is the weight of pearl sac formation
Want period.The mantle tissue of external source is implanted in acceptor hydriopsis cumingii mantle tissue, at this by way of manually performing the operation
Plant under stimulating, the outer embrane epithelial cell near stimulation point, drastically breeding gradually to surround stimulates former, eventually forms complete pearl
Capsule.Due to planting the stimulation of piece, hydriopsis cumingii occurs inflammatory reaction, peroxide can be largely produced in vivo, removes these peroxides
Compound is to protect freshwater mussel body from oxidative damage, as the necessary ways for promoting pearl sac and pearl to be formed.The study find that β-
Carrotene treatment group is compared with control group, and the vigor of beta carotene treatment group CAT enzymes is always above control group, illustrates β-Hu Luo
Bu Su can induce CAT enzymes, improve freshwater mussel body and remove H2O2Ability, promotes the formation of pearl sac.And with the extension of processing time,
There is the time effect of " first promoting to press down afterwards ", i.e. beta carotene and handle 30-120d in CAT enzyme activities in hydriopsis cumingii body, with when
Between extension CAT enzyme activity gradually rise, the vigor of CAT enzymes is most when handling 120d, in outer embrane, the gill, internal organ Youth League organization
Height, the significant difference (P compared with control group<0.05).Hereafter with the increase of beta carotene processing time, vigor is gradually reduced.
This explanation beta carotene has positive facilitation to the CAT enzyme activities of hydriopsis cumingii, but this effect be not it is endless,
Long between when treated, tolerance just occurs in hydriopsis cumingii, and the vigor of CAT enzymes will decline, occur " first promoting to press down afterwards " when
Between effect.
In addition, in this research, either beta carotene treatment group or blank control group, CAT enzymes in hydriopsis cumingii tissue
Vigor highest always in internal organ Youth League organization, minimum (being shown in Table 1) in mantle tissue, what this explanation hydriopsis cumingii was respectively organized
Metabolic capability is different, and internal organ Youth League organization highest, hydriopsis cumingii belongs to Filter feeding bivalves, by filtering the life of swimming in water body
Thing and organic debris obtain nutriment and calcium, and these materials enter after freshwater mussel body, it is necessary to could quilt by the metabolism of visceral mass
Utilize, substantial amounts of H can be produced during metabolism2O2、O2 -, and the high vigor of CAT enzymes is conducive to quickly removing H2O2、O2 -, have
Beneficial to the health for ensureing freshwater mussel body;The other gill is as the main Filtering apparatus of hydriopsis cumingii, and metabolic activity is also relatively more active, therefore group
CAT enzyme activities in knitting are higher, and mantle tissue is mainly used in nacreous deposition and forms pearl, thus CAT enzyme activities are most
It is low.
It is minimum in mantle tissue for the vigor of POD enzymes, secondly it is the POD enzyme activities in gill tissue, visceral mass group
Highest (being shown in Table 2) in knitting, distribution of this explanation POD enzyme in hydriopsis cumingii is organized is also uneven, and visceral mass is used as generation
The main place thanked, in order to avoid POD enzyme activities in the bad infringement such as peroxidating, internal organ Youth League organization occur for freshwater mussel body cell most
By force.Other beta carotene treatment group is always less than blank control group, and this explanation beta carotene has good to hydriopsis cumingii
Anti-oxidant facilitation, and CAT enzymes are higher than POD enzymes, under the induction of beta carotene, triangle to the sensitiveness of beta carotene
Substantial amounts of CAT enzymes are produced in sail freshwater mussel body, CAT enzymes will be metabolized the H produced2O2、O2 -Remove, in vivo excessive H2O2、O2 -Quantity is very
It is few, lack H2O2、O2 -Substrate, body avoids the need for substantial amounts of POD enzymes and continues the materials such as oxidation Decomposition phenol, amine, alcohol, aldehyde, thus
Beta carotene treatment group POD enzyme activities are always less than blank control group.With the extension of time, the work of the POD enzymes in each tissue
Power also occurs in that the time effect of " first promoting to press down afterwards ", this effect to POD enzymes of explanation beta carotene be also it is two-way, i.e., in short-term
Between in the range of 30-120d, play facilitation, be used for a long time more than 120d, an inhibitory action.
CAT and POD enzymes are the protective enzyme members in hydriopsis cumingii body, and the change of their activity imply that in beta carotene
In the presence of other enzymatic activitys related to metabolism are also in change in hydriopsis cumingii body, the change of internal metabolic enzyme certainly will influence three
The metabolism of angle sail freshwater mussel, and then influence CaCO3Crystallization and organic substrate secretion.In our current research, when beta carotene processing
During 90d, the CaCO of Margarita layer3The regular deposition of transistor die, organic substrate secretion is appropriate, CaCO3Crystal point
Layer phenomenon is obvious, and now the activity of CAT and POD enzymes is also higher in hydriopsis cumingii body, is metabolized vigorous, this explanation beta carotene
CAT and POD enzymatic activitys can be induced, promote CaCO3The crystallization of crystal in order, enhancing nacre to the reflection of light, reflect and spread out
Penetrate, lift the iridescence of pearl.
In addition for blank control group, CAT enzymes and POD enzymes in hydriopsis cumingii body can also occur after first raising over time
The effect of reduction, this is mainly influenceed by environment such as temperature, and this research is since May, and November terminates, and water temperature also undergoes
One be gradually increased to reduction process, water temperature can influence the enzyme system in hydriopsis cumingii body, and then influence CaCO3Crystal knot
Structure, thus improve Margarita layer CaCO applying beta carotene3During crystal structure, it should be noted that time of application, preferably select
The enzyme activity selected in hydriopsis cumingii body is stronger, water temperature higher period.
The influence that 4.2 beta carotenes are crystallized to Margarita:
Calcite, aragonite, ball aragonite are CaCO3Three kinds of anhydrous polymorphs, its thermodynamic stability is reduced successively.
Research finds the CaCO in nature3Mainly exist with calcite, ball aragonite and aragonite are actually rare in its natural state, and
With the difference of crystallization condition, any of which or several crystal formations can be formed.Pearl is the biomineralization production of hydriopsis cumingii
CaCO in thing, pearl3Which kind of exist with crystal formation affected by many factors.Research shows CaCO3In crystal aragonite composition it is higher,
CaCO3Crystal shape is more regular, and the iridescence of pearl is better.The study find that calcite, aragonite, ball aragonite coexist in pearl
In, and the mass fraction of three kinds of compositions can change.
For blank control group, the crystal structure of nacre is occurred in that from irregular rhombohedra particle (Fig. 4) to gradually becoming
The process (Fig. 6) of regular hexagonal, coarse irregular (Fig. 8, the Fig. 9) then become again, X-ray diffraction shows calcite in pearl
Mass fraction 30d be up to 10% (Fig. 3), be then gradually reduced.Illustrate under nature, the growth of pearl and CaCO3
Crystal microstructure can also change, the general higher convenient hydriopsis cumingii of breeding water body temperature with the change of cultivation season water body
Nacreous secretion and the growth of pearl.
For beta carotene treatment group, the mass fraction of calcite and ball aragonite and always less than blank control group (figure
3), illustrate that beta carotene can promote the formation of aragonite, reduce the content of calcite and ball aragonite.When the processing of beta carotene
When time is 90d, Margarita layer crystallization is best, and chip is in regular hexagon, and shape is clear, clear-cut;From exposed
Secondary top layer is visible, and secondary top layer is still constituted for regular hexagon chip, and the organic substrate of secretion promotes chip to arrange layer by layer, and structure is tight
Close, lamination is substantially (Fig. 6).Illustrate that beta carotene can promote the appropriate secretion of organic substrate, and the organic group secreted
CaCO can be promoted by containing in matter3With the material of the regular deposition of aragonite crystals, strengthen the iridescence of pearl.
Then with the extension of processing time, the content of aragonite will be reduced gradually, and the content of ball aragonite and calcite is then
Gradually rise.
4.3 summarize
Beta carotene can induce CAT enzymes, POD enzyme activities in hydriopsis cumingii outer embrane, the gill, internal organ Youth League organization, improve
The content of the mass fraction of aragonite in pearl, reduction ball aragonite and calcite, promotes the appropriate secretion of organic substrate, promotes
CaCO3The regular arrangement of aragonite chip, improves nacreous crystal structure, strengthens the iridescence and quality of pearl.
