图2 Vrn-B1 位点第1内含子等位变异图示 AY747604.1 vrn-B1 序列来源于NCBI数据库。皖麦33 Vrn-B1a 和豫麦34 Vrn-B1b 通过引物IntrBFP1和Intr1BR3 P2扩增后分别得到709 bp和673 bp条带。虚线表示通过比对缺失的碱基, 包含第一内含子的大片缺失A以及豫麦34和皖麦33之间36 bp小片段缺失B。细线表示未经测序的部分。
Fig. 2 Schematic diagram of variation comparison within the first intron at Vrn-B1 locus Sequence of vrn-B1 AY747604.1 is from the NCBI database. The 709 bp and 673 bp bands were amplified in wheat cultivars with alleles Vrn-B1a Wanmai 33 and Vrn-B1b Yumai 34 using specific primer pair Intr1BF P1 and Intr1BR3 P2, respectively. The large deletion within intron 1 A and 36 bp deletion in Vrn-B1b B are indicated by dashed lines. The parts without sequencing are indicated by thin lines.
