ER took part in cell wall material deposition during endosperm cell construction. ER rounded up matrix forming endocytic vacuole. ER cisterna swelling and accumulating starch developed into amyloplast. ER took part in protein synthesis and deposition, played a core role in protein body formation. ER swelled at the end to form many vesicles. ER was associated with the plasmodesmata, helped transporting nutrients at the development and differentiation stage.

内质网参与胚乳细胞构建中细胞壁物质的积累；内质网包裹基质形成吞噬体，为胚乳的发育提供营养；内质网槽库膨大，积累淀粉转变成淀粉质体；内质网参与蛋白质的合成与积累，在蛋白体的形成中处于核心地位；内质网末端节状膨胀，形成潴泡；灌浆高峰期内质网常与胞间连丝相连，有助于物质的运输。

The correction technology is taken on to improve the antipersonnel probability and make the navigation more precise.

采用末端修正技术，使导弹不是飞向目标发动机尾焰中心，而是飞向目标的要害处，这样可以提高杀伤概率，使导引精度进一步提高，以此提高作战效能，有效的摧毁空中目标。

Only one complete corollinae chromosome was detected in Ml4, and was determined corollinae chromosome 9. We have used in situ hybridization of genomic DNA to discrimination the parental chromosomes in Beta Ml 4, suppression of cross-hybridization by blocking DNA was not necessary indicating that the investigated Beta genome contain sufficient species-species DNA enabling the unequivocal determination of genomic composition of the hybrids.In our study , the results of BAC -FISH combined with the analysis of GISH in Beta M14,indicating that present of the corollinae chromosome 9 alone was sufficient to confer apospory in Beta M14 upon celluar and molecular..
