Metabolomic and Transcriptomic Analyses of Lycium barbarum L. under Heat Stress

Heat stress has a strong and detrimental effect on plant growth yield. Goji berry or wolfberry (Lycium barbarum L.) is dual-purpose medicinal food but an increase in high temperatures caused serious decline yield quality. In this study, we first explored the heat responses of berry, found that adaptation mechanisms fluctuated over 48 h. Moreover, L.barbarum 1402 was more resistant while Ningqi No. 7 (N7) sensitive to temperatures, which amino acids alkaloids played key roles; expression accumulation timing also crucial. That is, responded rapidly starting at 1 h under temperature, activated related genes, accumulated metabolites earlier acid metabolic pathway compared N7, 3 temperature. Thus, resisted much better N7. Furthermore, joint transcriptome metabolome analysis results showed L-phenylalanine, L-tyrosine, N-benzylformamide, N-benzylmethylene isomethylamine, lysoPC 19:1, N-acetyl-D-glucosamine-1-phosthate, as well their were higher content, expression, N7 treatment. This study initially elucidates tolerance than for when temperatures.
