Transcriptional changes regulating secondary metabolism
Severe P-deprivation led to decreases in transcript levels of genes related to secondary metabolism, including isoprenoid, phenylpropanoid, and flavonoids, including anthocyanins metabolism (Table S3 ). In contrast, DEGs encoding for enzymes involved in the biosynthesis of diterpenes, such as phytoalexins, were highly induced in shoot under severe P-stress (Table S3 ).
