The paper develops ACE and ACE2 reporters to study hormone interactions in Arabidopsis roots, revealing spatial and temporal auxin-cytokinin-ethylene crosstalk mechanisms.

The paper investigates the relationship between ascorbate levels and auxin biosynthesis in Arabidopsis by analyzing mutant lines with altered ascorbate concentrations.

This study shows that gene families involved in the IAOx pathway are not essential for auxin biosynthesis in Arabidopsis, challenging the proposed linear pathway and suggesting an uncharacterized route.

The paper develops and tests EBSn, a synthetic ethylene-inducible promoter that outperforms existing reporters in sensitivity and tissue coverage in Arabidopsis and tomato.

The paper identifies GDP-O_SCPLOWLC_SCPLOW-galactose phosphorylase as the main control point in ascorbate biosynthesis through metabolic engineering, genetic analysis, and functional mutant complementation.
