Abstract excerpt

Branched-chain amino acid (BCAA) accumulation has been linked to the induction of salicylic acid (SA)-related defense responses in wheat (Triticum aestivum). Here, we explored whether the underlying mechanism might involve a wheat ortholog of SAP AND MIZ1 DOMAIN-CONTAINING LIGASE1 (SIZ1), a critical SA regulator in other systems. We found that TaSIZ1 was significantly repressed in mutant plants disrupted in the...
