Cysteine homeostasis plays an essential role in plant immunity.

The New phytologist - 1 Jan 2012

Álvarez Consolación, Ángeles Bermúdez M, Romero Luis C, Gotor Cecilia, García Irene

Abstract excerpt

• Cysteine is the metabolic precursor of essential biomolecules such as vitamins, cofactors, antioxidants and many defense compounds. The last step of cysteine metabolism is catalysed by O-acetylserine(thiol)lyase (OASTL), which incorporates reduced sulfur into O-acetylserine to produce cysteine. In Arabidopsis thaliana, the main OASTL isoform OAS-A1 and the cytosolic desulfhydrase DES1, which degrades cysteine,...
