Gene | Function | PAMP | Reference |
---|---|---|---|
Ethylene Response Factor 1 [ERF1] |
Transcriptional activator which acts downstream of the ethylene signaling pathway. It mediates development and regulates pathogen defense genes [16]. | harpin and flg22 | [2,17] |
Ethylene Insensitive Protein 5 [EIN5] |
Required for plant growth enhancement [2]. Acts downstream of CTR1, a negative regulator of the pathway. If ethylene is present, CTR1 does not act, and the pathway can be activated [3]. | harpin | [3] |
Ethylene Insensitive Protein 2 [EIN2] |
Required for insect resistance in plants [2]. Protein located downstream of CTR1 in the ethylene pathway. If CTR1 is inhibited, then EIN2 may be activated. It is a Nramp-like protein, meaning it is a natural resistance-associated macrophage protein [18]. | harpin | [2,18] |
Flg22-Induced Receptor Like Kinase 1 [FRK1] |
Associated with early defense signaling as well as mediating senescence. Following flg22 exposure in an organism, FRK1 regulation likely increases accordingly [19]. | flg22 | [19] |
Pathogenesis Related Protein 1 [PR1] |
Gene expression increases following pathogen detection [20]. It is an indicator of systemic acquired resistance. | flg22 | [21] |
