The result of SsSAMS2 expression and polyamines (PAs) content analysis of three lines (ST8-9, ST14-2, ST3-5) showed that SsSAMS2 expressed in transgenic tobacco, and transgenic tobacco accumulated more soluble total PAs content than wild-type plants.
共筛选到8个转基因纯合品系,分析其中3个品系(ST8-9、ST14-2、ST3-5)基因表达和多聚胺含量的结果表明,SsSAMS2可在转基因烟草中表达,转基因烟草中的多聚胺含量明显高于野生型烟草。
