Summary of sugarcane metabolites and their role in plant growth and stress responses.
| Metabolites | Function | Reference |
|---|---|---|
| Sucrose, glucose, fructose, inositol and raffinose | Helpful in screening genotypes with high sucrose content | [110] |
| Apigenin 7-O-(6″-O-acetylglucoside) | Increased susceptibility to Sporisorium scitamineum SSC39 teliospores | [117] |
| Proline | Enhanced resistance against salt stress | [120] |
| Sodium (Na+) | High production of Na+ content in sugarcane leaves increase susceptibility to salinity stress | [121] |
| Proline, soluble phenolic, anthocyanins, and flavones | Increased production of these metabolites enhance resistance against drought and salinity stress | [121,122] |
| K+ and Ca2+, soluble sugars and proline content | Improved heat stress tolerance | [123] |
| Sucrose | Helps in sugar metabolism, pentose phosphate cycle, phenylpropanoid and α-ketoglutarate metabolism | [124] |
| Sucrose, putrescine, glutamate, serine, and myo-inositol | Enhances axillary bud outgrowth | [125] |
| Ethylene (ET) | Induced sucrose accumulation | [126] |
| Ascorbic acid (ABA) | Induce proline contents, mitigating salinity stress | [127] |
