Abstract:
Mounting of efficient plant defence responses depends on the ability to trigger a rapid defence reaction after recognition of the invading microbe. Activation of plant resistance is achieved by modulation of the activity of multiple transcriptional regulators, both DNA-binding transcription factors and their regulatory proteins, that are able to reprogram transcription in the plant cell towards the activation of defence signalling. Here we provide an overview of recent developments on the transcriptional control of plant defence responses and discuss defence-related hormone signalling, the role of WRKY transcription factors during the regulation of plant responses to pathogens, nuclear functions of plant immune receptor proteins, as well as varied ways by which microbial effectors subvert plant transcriptional reprogramming to promote disease.

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.
