Abstract:
Phenols are toxic, environmentally persistent products of the chemical industry that are capable of bioaccumulation and biomagnifications in the food chain. Little is known of how plants respond to this compound. To understand the transcriptional changes under phenol, microarray experiments on Arabidopsis thaliana were performed. Microarray results revealed numerous perturbations in signaling and metabolic pathways. The results indicated that the phenol response was related to reactive oxygen species (ROS) accumulation and oxidative conditions, including ROS generated for pathogen defense.

Transcription
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
Transcription Can Produce Different Kinds...
Responses to Heat and Cold Stress
Other Stress Responses in Bacteria
Responses to Salt Stress
Responses to Drought and Flooding
