摘　　要：以番茄自交系1479为材料,利用基因编辑技术创制番茄组蛋白变体H2A.Z基因双突变体hta11hta9。测序结果表明番茄H2A.Z基因被敲除。发芽试验结果表明组蛋白基因H2A.Z双突变体hta11hta9种子萌发受到严重影响。在相对低温(17℃)下,H2A.Z基因双突变体生长明显比野生型迟缓。Using tomato inbred line 1479 as the material,a double mutant of H2A.Z gene of histone variant hta11hta9 was obtained by gene editing technique. Sequencing analysis showed that the tomato H2A.Z gene was knocked out. The results of germination experiment showed that H2A.Z double mutant hta11hta9 had a serious effect on seed germination. The growth of H2A.Z double mutant hta11hta9 was obviously slower than wild type under the relative low temperature of 17 ℃.
