Description |
Lines carrying recessive alleles exhibit early leaf senescence both in air and upon ethylene exposure. The etiolated old1 seedlings exhibited a hypersensitive triple response. |

Organism |
Arabidopsis thaliana |
Description |
A genetic locus involved in leaf senescence in response to ethylene. Lines carrying recessive alleles exhibit early leaf senescence both in air and upon ethylene exposure. The etiolated old1 seedlings exhibited a hypersensitive triple response. Regulator of expression of pathogenesis-related (PR) genes. Participates in signal transduction pathways involved in plant defense (systemic acquired resistance -SAR). |
