JF - Grasas y Aceites JA - Grasas aceites VL - 67 IS - 4 SE - Research DO - 10.3989/gya.0322161 UR - https://grasasyaceites.revistas.csic.es/index.php/grasasyaceites/article/view/1630 SP - e164 AB - Although phosphoenolpyruvate carboxylases (PEPCs) are reported to be involved in fatty acid accumulation, nitrogen assimilation, and salt and drought stresses, knowledge regarding PEPC gene functions is still limited, particularly in peanuts (<em>Arachis hypogaea</em> L.). In this study, the antisense expression of the peanut PEPC isoform 1 (<em>AhPEPC1</em>) gene increased the lipid content by 5.7%–10.3%. This indicated that <em>AhPEPC1</em> might be related to plant lipid accumulation. The transgenic plants underwent more root elongation than the wild-type under salinity stress. Additionally, the specific down regulation of the <em>AhPEPC1</em> gene improved the salt tolerance in peanuts. This is the first report on the role of PEPC in lipid accumulation and salt tolerance in peanuts. ER -
