Ureides are similarly accumulated in response to UV-C irradiation and wound but differently remobilized during recovery in Arabidopsis leaves.

This study shows that UV-C and wounding trigger purine degradation in Arabidopsis, leading to ureide accumulation, which is remobilized differently during recovery to support growth or healing.

Impairment in O-acetylserine-(thiol) lyase A and B, but not C, confers higher selenate sensitivity and uncovers role for A, B and C as L-Cys and L-SeCys desulfhydrases in Arabidopsis

This paper shows that OASTL A and B, but not C, are involved in degrading L-cysteine and L-selenocysteine in Arabidopsis, leading to increased selenate sensitivity.
