ABSTRACT
The involvement of zinc (Zn) in terms aroma formation has been rarely investigated. This study shows that the regulation 2-acetyl-1-pyrroline (2AP) biosynthesis was evaluated two different rice cultivars under foliar Zn application. results showed 2AP and contents leaves grains were improved substantially content positively related to expression P5CS2 gene, proline, 1-pyrroline, Δ1-pyrroline-5-carboxylate (P5C), activity pyrroline-5-carboxylate synthase (P5CS) application fragrant rice. Multiple transcription factors (TFs) differently expressed, such as bZIPs, NACs, MYBs, play a role treatments rice, suggesting crucial 46 expressed TFs improvements Furthermore, this optimal at concentration 30 mg L–1 could increase aromatic keep yield stable or yield. involved regulating promote However, relationship between pathway genes remains be further studied.
