Plant responses to various stresses are complex, involving alterations in the physiological, cellular, and transcriptome levels. Polyamine accumulation in diseased tissues is difficult to identify as it is found in both pathogenic fungus and plants. Abiotic stressors, as a group, pose a serious challenge to the ecosystem and agriculture also responsible for significant agricultural production losses. Benzoxazinoids are plant secondary metabolites found in grasses that have a significant potential for chemical defense against biotic stresses seen across the animal world. EREBP (Ethylene Response Element Binding Protein) transcription factor gets highly expressed in association with the ROS scavenging system, with decreased expression of the dehydrogenases gene. Crop productivity is also affected by biotic stresses. Plants physiological characteristics are altered by drought, excessive heat, and with their combined effect. Heat and drought stress have been proven to affect photosynthetic activity. Hydroponic systems operate by allowing precise control of environmental factors such as pH-balance and temperature, as well as increased nutrient and water exposure.
