| 英文摘要 | Background and aimsPhosphate (Pi) is an essential nutrient for plant growth and development. Accessible Pi is usually limited in soil and Pi starvation is a global stress for crops. Genetic approach is promising for sustainable agriculture to improve plant growth under Pi starvation. The aim of this study is to explore the role of transcription factor NUTCRACKER (NUC) in response to Pi starvation.MethodsThe seedlings growth, biomass, chlorophyll and anthocyanin contents, root morphology, phosphate starvation-induced (PSI) genes expression in NUC knockout, rescue and overexpression Arabidopsis lines were examined and compared under Pi sufficiency (CON) and Pi starvation conditions.ResultsArabidopsis lines overexpressing NUC significantly improved their growth under Pi starvation by attenuating Pi starvation-induced harmful effects. NUC expression was significantly upregulated in roots and positively affected root development under Pi starvation. Specifically, overexpression of NUC elongated primary roots under Pi starvation by increasing meristem size and elongation zone, promoted the growth of Pi-starvation-induced root hairs, and increased the expression of phosphate starvation-induced genes in roots.ConclusionOverexpression of NUC conferred plants by tolerate to Pi starvation, and the promotion to root hair could be the main reason. NUC has the potential to improve plant growth under Pi starvation. |
