Technical field
The present invention relates to a kind of methods that the polar growth field of pollen tube more particularly to pollen tube load fluorescent dye.
Background technology
The normal growth of pollen tube is multi-signal molecular regulation as a result, and calcium ion plays important work wherein
With.The higher calcium gradient in pollen tube cytoplasm tip is had observed that in various plants, the disappearance of calcium concentration gradient can cause to spend
Tube cell growth stops.Pollen tube top high calcium gradient may have following functions:First, it may participate in the adjusting of vesica secretion,
Because the calcium of high concentration is conducive to merging for Secretory vesicles and plasma membrane, outer row is promoted to act on, extends pollen tube;Second, high concentration
Calcium makes depolymerization of microfilaments, and the movement of organelle slows down, so calcium gradient can influence organelle by controlling the assembling of microfilament
Transport;Third, the calcium of high concentration is related with pollen tube oriented growth, and the free calcium ions of pollen tube top high concentration can inhibit flesh
The movement of filamentous actin-myosin regulation and control precipitates vesica, if increasing cytosolic free calcium concentration in pollen tube side, can make flower
Tube cell changes the original direction of growth, is grown to high calcium concentration side.For the effect of calcium ion in further Study of Pollens pipe,
We can use fluorescent labelling techniques.Fluorescence indicator is indispensable mark substance in this course, in plant flowers
Increasingly important role is played in tube cell construction and growth characteristics research.Currently used fluorescence indicator, which has, not to be destroyed
Eucaryotic cell structure under the premise of maintaining tissue activity, passes through fluorescence microscope, laser confocal microscope and flow cytometer etc.
The measure of feature instrument can obtain the specific fine structure of pollen tube and histofluorescence image.The success of this method will be based on
Dyestuff is successfully loaded into pollen (pipe), at present, the type of calcium ion fluorescent has:Single wavelength fluorescence probe, including
Fluo-3, quin-2, Calcium Green, Calcium Orange etc.;With double wave length fluorescent probe, mainly have indo-1,
Fura-2, fura-red etc..The stowage of calcium ion fluorescence indicator has:Electroporation (this method is big to cellular damage, if
Standby expensive, do not have to typically now), (this method has cell a degree of damage, in addition complicated for operation, work for microinjection
Amount is big, success rate is low, be not suitable for the smaller cell of individual, is not suitable for the shortcomings of cell batch all limits this method
Extensive use, patch-clamp (speed is slow, equipment is expensive), low temperature process (time is long), high temperature method (influencing survival).More than overcoming
Deficiency, need explore fast and effeciently load fluorescent dye method.

40mM。
The coloring agent is acetoxymethyl ester derivative, can with penetration cell film, into cell after can be by intracellular esterase institute water
Solution, the Fluo-4 of generation then can with calcium binding and send out fluorescence.
Beneficial effects of the present invention are:
The coloring agent (Fluo-4 AM-ester) that the method that a kind of pollen tube of the present invention loads fluorescent dye uses is a kind of
It can be with the fluorescent dye of penetration cell film, mainly by the calcium binding that dissociates with intracellular and iuntercellular to Ca2+Signal point
Cloth carries out quantitative analysis, it sensitive can reflect the variation of free intracellular calcium concentration, and coloring agent enters after cell through non-spy
Different in nature esterase is sloughed AM and is stayed in into the cell as Fluo-4, its fluorescence intensity is itself after Fluo-4 is combined with intracellular free calcium
More than 40 times or more.When studying intracellular calcium using calcium ion fluorescent combination fluorescence analysis, fluorescent dye
