Plants Defense System Resist against the Pathogen Attack: Transcription Factors in Focus
Transcription factors play important roles to drive different pathways by regulating gene expression. Apart from gene expression regulation, these TFs also have vital importance in plant immune system. Both PTI and ETI mode if immunity is important for plants but ETI has a central role in the defense system of a plant. ETI activates the hypersensitive response in which programmed/localized cell death is involved which ranked ETI quantitatively stronger than PTI which is effective in host resistance defense mechanism. Phytohormone such as salicylic acid, jasmonate, abscisic acid and ethylene and their components interact each other either positively or negatively. Their role in plant defense response has been documented.
