The AP2/ERF domain transcription factor ORA59 integrates jasmonic acid and ethylene signals in plant defense.

abstract：:Induction of secreted acid phosphatase (APase) is a universal response of higher plants to phosphate (Pi) limitation. These enzymes are thought to scavenge Pi from organophosphate compounds in the rhizosphere and thus to increase Pi availability to plants when Pi is deficient. The tight association of secreted APase w...
