“…Given that FA is an intermediate in the biosynthesis of various aromatic compounds in the phenylpropanoid pathway ( 41 ), therefore we further analyzed whether and how FA treatment influences the aroma quality of fresh-cut taros following long-term cold storage. Rare volatile compounds were identified in taros by using a GC-MS assay ( Figure 7 ).…”

“…The most significantly enriched pathway in leaves was plant hormone signal transduction (ko04075), while phenylpropanoid biosynthesis (ko00940) was enriched in the root, and there were as many as 26 DEGs in this pathway. Upregulation of phenylpropanoid biosynthesis was reported in cucumbers when pre-storage cold acclimation was applied to enhance plant cold tolerance [ 45 ]. In maize, 14 genes of the phenylpropanoid biosynthesis pathway were significantly upregulated in tolerant lines [ 46 ].…”

“…These DEGs were mostly enriched in secondary metabolic processes dominated by phenylpropanoid metabolism. The phenylpropanoid metabolic pathway is a main metabolic pathway in crops [ 26 ], which produces a wide range of secondary metabolites such as phenols, lignans, flavonoids, and alkaloids under the action of various enzymes and plays a critical role in resistance to stress from adversity, phytochrome formation, and cellular lignification processes [ 17 , 27 , 28 ]. In our work, 16 genes involved in the metabolic process of phenylpropanoid were significantly expressed after the addition of silicon, indicating that silicon addition could enhance the secondary metabolic capacity of cucumber, which in turn enhanced its cold tolerance.…”

“…Lipid metabolism, including membrane lipid and fatty acid metabolism, highly influences the response to cold stress [ 15 , 16 ]. Phenylpropanoid metabolism [ 17 ], phytohormone signaling [ 18 ], and transcription factors [ 19 ] have also been reported to regulate cold tolerance in crops. Transcriptome analysis has also been used to understand cold tolerance in horticultural crops such as tomato [ 20 ], watermelon [ 21 ], and eggplant [ 22 ].…”
