( 3 ) incubation of zona - free hamster eggs with spermatozoa pretreated with pmr a ntiserum was associated with a dose - dependent significant reduction in the number of spermatozoa binding to the oolemma, compared with a contraband with a dose - dependent reduction of the fertilization rate and the penetration index. the results indicate that mr of human sperm plays an important role in sperm - oocyte fusion and oocyte activation
結果顯示： （ 1 ）人精子mr能夠誘發去透明帶金黃地鼠卵母細胞中皮質顆粒的胞吐，並引起卵母細胞膜表面微絨毛形態和數量發生改變； （ 2 ）皮質顆粒胞吐后，其內容物可結合到卵膜表面； （ 3 ）抗mr抗血清預處理精子可抑制精子與卵子的結合與融合，使受精率、穿透指數和結合指數下降，並均有劑量依賴性。以上結果提示，人精子mr在受精過程中起重要作用，其主要作用可能是介導精-卵膜融合併促進卵母細胞的活化。It has been proved that hereditary basis can be improved to create new varieties by different ways or methods such as introducing overseas germplasm resources to transduce into wild species, mutagenic breeding, space breeding, biotechnology breeding, etc., it is possible to improve mightily sugar beet breeding
