摘要和关键词

摘要: 番茄(Solanum lycopersicum)具有较高的营养价值，深受消费者的喜爱，目前番茄已经成为广泛种植的经济作物之一。BLISTER(BLI)蛋白是许多应激反应的调节因子，可以促进植物对环境的适应性，在调控植物成熟方面发挥了重要作用。文章以番茄的SlBLI2(Solyc12g097070.3)基因为研究对象，对BLI家族的基因序列特征进行分析。通过SlBLI2基因的特异性区域沉默序列，利用同源重组技术成功构建了番茄StBLI2病毒诱导的基因沉默(virus-induced gene silencing, VIGS)载体。文章利用基因沉默实验对番茄果实注射不同杆菌，发现SlBLI2具有抑制果实成熟功能，为进一步探究番茄SlBLI2基因在果实成熟中的作用提供参考。

Abstract and Keywords

Abstract: Tomato(Solanum lycopersicum) has high nutritional value and is popular among consumers. Currently, tomato has become one of the widely grown cash crops. The BLISTER(BLI) protein is a regulator of many stress responses, which promotes plant adaptation to the environment and plays an important role in regulating plant maturation. In this paper, the SlBLI2(Solyc12g097070.3) gene of tomato was used to analyze the sequence characteristics of the BLI family genes. By finding the specific region silencing sequence of the SlBLI2 gene, a tomato SlBLI2 virus-induced gene silencing(VIGS) vector was successfully constructed using homologous recombination technology. The tomato fruits were injected with different bacteria using gene silencing assay, and SlBLI2 was found to have a function in inhibiting fruit ripening, providing a reference for further investigation into the role of the tomato SlBLI2 gene in fruit ripening.

Keywords: tomato (Solanum lycopersicum); virus-induced gene silencing (VIGS) vector; SlBLI2 gene; homologous recombination; ripening and senescence
