Integrated transcriptomic and metabolomic analyses reveal key metabolic pathways in response to potassium deficiency in coconut (Cocos nucifera L.) seedlings.

ABSTRACT: Potassium ions (K⁺) are important for plant growth and crop yield. However, the effects of K⁺ deficiency on the biomass of coconut seedlings and the mechanism by which K⁺ deficiency regulates plant growth remain largely unknown. Therefore, in this study, we compared the physiological, transcriptome, and metabolite profiles of coconut seedling leaves under K⁺-deficient and K⁺-sufficient conditions using pot hydroponic experiments, RNA-sequencing, and metabolomics technologies. K⁺ deficiency stress significantly reduced the plant height, biomass, and soil and plant analyzer development value, as well as K content, soluble protein, crude fat, and soluble sugar contents of coconut seedlings. Under K⁺ deficiency, the l
