藜麦NAC转录因子CqNAC66响应干旱和盐胁迫的功能研究
Functional analysis of quinoa NAC transcription factor CqNAC66 in response to drought and salt stress
为探究藜麦NAC家族成员CqNAC66基因的抗旱耐盐功能,本研究对CqNAC66进行亚细胞定位,并将CqNAC66基因导入本氏烟草中进行过表达,比较野生型和转基因株系在干旱(20%PEG-6000)和盐(200 mmol·L-1 NaCl)胁迫下的形态及生理响应。结果表明,CqNAC66转录因子定位在细胞核中;过表达CqNAC66能够显著降低烟草植株的离体叶片失水率;在干旱和盐胁迫下,过表达CqNAC66能够显著降低烟草的萎蔫指数,并显著提高烟草叶片的表面积和地上部鲜重;过表达CqNAC66能够显著提高烟草叶片的叶绿素相对含量(SPAD值)和过氧化物酶活性,显著降低丙二醛含量。综上所述,CqNAC66在烟草中的异源表达能够显著提高烟草植株的抗旱性和耐盐性,CqNAC66可能通过保持植株的叶绿素稳定,调节植物的抗氧化酶系统,缓解胁迫造成的细胞氧化损伤来提高转基因烟草抵抗干旱和盐胁迫的能力。
This research explored the function of quinoa (Chenopodium quinoa) NAC family member, CqNAC66 involved in drought resistance and salt tolerance. CqNAC66 was subcellularly localized in this study, and transgenic lines of Nicotiana benthamiana overexpressing CqNAC66 were obtained to compare the morphological and physiological responses of wild-type (WT) and transgenic plants after exposure to drought (20% PEG-6000) and salt (200 mmol·L-1 NaCl) stress. The results showed that CqNAC66 protein was subcellularly localized in the nucleus. Overexpression of CqNAC66 significantly decreased the water loss rates of excised leaves of tobacco plants. Under drought and salt stress treatment, overexpression of CqNAC66 in tobacco plants significantly decreased the leaf wilting index, and significantly increased the leaf surface area and aboveground fresh weight. In addition, overexpression of CqNAC66 significantly increased the relative content of chlorophyll (SPAD) and the activities of peroxidase, and significantly decreased the content of malondialdehyde in leaves of the studied tobacco plants. In conclusion, the heterologous expression of CqNAC66 in N. benthamiana improved the drought and salt tolerance of plants and CqNAC66 appeared to improve the resistance of transgenic tobacco by maintaining the stability of chlorophyll, regulating the plant antioxidant enzyme system and alleviating the cellular oxidative damage caused by stress.
