摘要:

【目的】 研究新疆海岛棉不同材料愈伤组织培养体系,筛选再生能力强的海岛棉材料,为新疆海岛棉基因工程育种提供参考。【方法】 以105份新疆海岛棉为材料,利用改良后的MS培养基对下胚轴共培养,在2,4-D诱导培养基中诱导分化产生愈伤组织,浸染农杆菌介导的红色荧光蛋白,验证转化效果。【结果】 海岛棉材料愈伤组织的增殖速率与其基因型有关,改良后的MS共培养基、2,4-D诱导培养基可有效用于新疆海岛棉共培养和胚性愈伤组织增殖;愈伤组织增殖的适宜培养时间为4个月,时间过长不利于其增殖;愈伤增殖速度与转化率呈正相关,增殖快的材料其红色荧光蛋白的转化率较高;筛选出2份增殖快且转化率好的海岛棉材料。【结论】 建立了新疆海岛棉胚性愈伤组织培养体系与鉴定方法,筛选出9份愈伤增殖好、且能够有效转化的海岛棉材料。

Abstract:

【Objective】 To explore the callus culture system of different materials of Xinjiang island cotton and to select variety with strong regeneration ability.【Method】 With 105 accessions taken as research materials, hypodermal axis was cocultured with modified MS media, callus differentiation was induced in the 2,4-d-induced medium. After that, the conversion effect was verified by immersion-mediated red fluorescent protein.【Result】 The proliferation rate of the callus in island cotton was related to different genotype. The improved MS co-medium and 2,4-D induction medium could be effective for the co-culture and embryogenic callus proliferation of Xinjiang island cotton. The appropriate culture time was 4 months for callus proliferation, and long time was not benefit for proliferation. Callus proliferation speed was positively correlated with the conversion rate, showing the material had a higher conversion rate of red fluorescent protein with the fast proliferation. Altogether, two island cotton accessions with fast multiplication and good conversion rate were selected. 【Conclusion】 In this study, the embryogenic callus culture system and identification method of Xinjiang island cotton are initially established, island cotton materials that have 9 good callus proliferation are screened out and that can be effectively transformed.
