植物花粉管中类整联蛋白的免疫荧光定位研究 总被引:2,自引:0,他引:2
The Strong fluorescence signals were obtained in pollen tube of Lilium davidii Duch with labeled anti-VnR integrin serum, and anti-beta 3, alpha v integrin subunit cytoplasmic domain serum separately. The highest density of immunolabel was in the tip of pollen tube. There was little or no immunolabel in control experiment using non-immune serum, second antibody alone and anti-FnR, LnR integrin serum separately. In pollen of Prunus persica f. rubro-piena Schneid, fluoresence signals were also obtained in tube using labeled anti-beta 1, beta 3 integrin subunit cytoplasmic domain serum separately and in apertures using anti-beta 1 serum. Preliminary results show that during the germination of pollen and the growth of pollen tube, there may be integrin-like proteins in pollen tube, consisting of alpha v and beta s integria subunits in the pollen tube of Lilium davidii Duch, which is the receptor of vitronectin-like protein. 相似文献
