Abstract: Unlike other phytohormones, ethylene is considered as an important plant gases hormone in regulating numerous plant developmental processes such as germination of seeds, elongation of cell organs, flower opening, ripening of fruit, organ senescence and as well as abscission. It holds a simple structure compared to the rest of the plant growth substances. Ethylene is normally generated by higher plants and is usually linked to fruit ripening and specific triple response. Generally, all kinds of biotic and abiotic stresses including temperature fluctuations, water imbalance, salt issues, pathogen or insect attacks holds certain specific kind of negative influence on the plants growth and development. Transcription factors are known for their crucial functions in signal transduction to trigger or repress expression of defense gene, along with in the modulation of connectivity among various signaling pathways. ERF genes are observed to be stimulated not only with disease-concerned and pathogen infection stimuli, but its expression levels can also be trigger due to abiotic stresses, thus in this way ERF genes can improve the multiple stress resistances in the transgenic plants. Furthermore, over-expression study analysis of ERF gene revealed that these transcription factors can bring a broad-spectrum resistance towards pathogens and other abiotic stresses and can also the tolerance in transgenic plants towards drought, salt, and freezing. Thus, ERF gene is focus under this specific research study in order to explore its role in relation to abiotic stress such as ethylene stimuli.
