Integrated transcriptomic and metabolomic analysis reveals key genes and core metabolic pathways involved in phosphorus stress response in quinoa flower spikes.

ABSTRACT:

Background

Quinoa is native to the Andes Mountains, where the ecological environment is relatively harsh, making it highly resilient in adapting to its environment. In the flower spike stage, phosphorus (P) is vital for plant metabolism and signaling. Here, we analyzed the flower spike response to low and high P stress.

Results

A total of 1891 metabolites were identified among the three subgroups: control (CB, CY), high P (HB, HY), and low P (LB, LY), where Y represents Dianyuli 1, and B represents Dianyuli 3. There were 290 and 164 differentially expressed metabolites (DAMs) in LB vs. CB and LY vs. CY, respectively, and 144 and 248 DAMs in HB vs. CB and HY vs. CY, respectively. A total of 53,202 genes were annotated using transcriptome analysis, with 2,818 and 3,628 differe
