1) The wall of the generative cell contains callose.

2) Subsequently, after meiosis, the callose decayed centripetally and released four immature microspores and this phenomena suggested the types of cytokinesis the mixture of simultaneous and successes.

3) The formation of the callose wall occured at the PMC stage.

4) No callose fluorescence shows in the wall of mononuclear embryo sac after its formation, while thick callose deposits in the wall of the degenerative megaspore.

5) It was found that the callose component initially occurred at late sporogenous cells stage in the cells located in center of microsporangium, and late extended towards the cells lying at its two ends.

6) Ligni, spile and callose accumulated significantly in cells of cortex after treatment with BTH or Harpin.

7) In addition, correlations between the meiosis and callose deposition in the wall of megasporocyte have been discussed.

8) Callose stains are aniline blue, resorcin blue and rosolic acid.

9) As development goes on(sentencedict.com), callose fluorescence disappears in the chalazal wall of diplosporous functional megaspore.

10) During meiosis, callose deposit on the micropylar end wall of the megasporocyte, but the cell was not enclosed by callose.

11) The accumulation of callose was benefit to dispersion of pollen mother cells and microspores.

12) Abnormalities of the content and distribution of callose and phenolics are also mentioned.

13) Hypersensitive reaction and callose formation were two important resistance mechanisms.

14) Staining with the improved carbolfuchsin- aniline blue fluorescence method is a convenient and efficient way to observe the behavior of the callose wall of microspore mother cells during meiosis.

15) These phenomena may be related to the conveyance of implanted ions across cell wall,[http://sentencedict.com/callose.html] or be related to the accumulation of callose.

16) Sieve area pores of mature sieve elements are lined with the thicker callose and plugged with the electron-opaque P-protein, which may be the response to wounding on the phloem in preparing samples.

17) Incompatible pollen is blocked initially by pectins followed by callose deposition.

18) At the stage of meiosis prophase, microspore mother cell begin to accumulate callose wall.

19) Incompatible pollen tubes grow more slowly and, at least in some, the pollen tube bursts before it reaches the ovule and the polysaccharide callose is deposited around the tube.

20) In the grasses the pollen tube is blocked at the stigma surface with pectins and callose.

21) Secondly, if pollen tubes entered into stigma, growth was retarded with callose plug deposition, then they stopped to grow because of inhibition.
