摘要: 类病变突变体(lesion mimic mutant)是一类研究细胞死亡与抗病机制的有效工具。试验以水稻类病变突变体spl5为材料,构建了spl5突变体的胚性悬浮细胞系。结果表明诱导spl5突变体愈伤组织的最佳2,4-D浓度为2 mg·L-1,疏松的Ⅱ型胚性愈伤组织经悬浮继代培养3~4个月后可获得理想的胚性悬浮细胞系,FDA-PI染色结果表明该细胞悬浮体系活力高。水稻类病变突变体spl5胚性悬浮细胞系的建立可为进一步研究spl5突变体细胞死亡及其与病原菌互作的机制奠定基础。

Abstract: Lesion mimic mutant is a powerful tool to study the mechanisms of cell death and disease resistance. This study established a suspension-cell line of spl5, a rice lesion mimic mutant. For spl5 mutant, the optimum concentration of 2,4-D was 2 mg·L-1 in callus induction and the ideal embryogenic suspension-cell line, from osteoporosis type Ⅱ embryogenic callus, was achieved after cultured 3-4 months in suspension medium. After FDA-PI staining, the suspension-cell line of spl5 mutant showed high viability, and could be used in the further study on the mechanism of cell death and interaction with pathogen in spl5 mutant.

Key words: rice, lesion mimic mutant, spl5, suspension-cell line
