“…96,97 Transcription regulators, including transcription factors and their regulatory proteins, have been proven to fine-tune the plant defense transcriptome. 96,97 Well-known examples include WRKY and TGA transcription factors, which participate in the regulation of basal resistance and ETI. [98][99][100][101][102][103][104][105] Several recent studies have demonstrated that TCP transcription factors also function as a cellular hub in plant defense signaling.…”

“…Effective plant immunity requires the efficient perception of potentially pathogenic microbial-associated molecular patterns (MAMPs) by a range of host-encoded extracellular pattern recognition receptors (PRRs) (Belkhadir et al, 2014;Böhm et al, 2014;Macho and Zipfel, 2014;Zipfel, 2014). These stimuli are translated into the rapid transcriptional activation of a network of MAMP-triggered immunity (MTI) responses (Buscaill and Rivas, 2014). This germ-lineencoded MTI provides robust defense against a diverse variety of pathogens and offers biotechnological potential to improve resistance in elite crop varieties.…”

Transcriptional Dynamics Driving MAMP-Triggered Immunity and Pathogen Effector-Mediated Immunosuppression in Arabidopsis Leaves Following Infection with Pseudomonas syringae pv tomato DC3000

Transcriptional reprogramming is integral to effective plant defense. Pathogen effectors act transcriptionally and posttranscriptionally to suppress defense responses. A major challenge to understanding disease and defense responses is discriminating between transcriptional reprogramming associated with microbial-associated molecular pattern (MAMP)-triggered immunity (MTI) and that orchestrated by effectors. A high-resolution time course of genome-wide expression changes following challenge with Pseudomonas syringae pv tomato DC3000 and the nonpathogenic mutant strain DC3000hrpA-allowed us to establish causal links between the activities of pathogen effectors and suppression of MTI and infer with high confidence a range of processes specifically targeted by effectors. Analysis of this information-rich data set with a range of computational tools provided insights into the earliest transcriptional events triggered by effector delivery, regulatory mechanisms recruited, and biological processes targeted. We show that the majority of genes contributing to disease or defense are induced within 6 h postinfection, significantly before pathogen multiplication. Suppression of chloroplast-associated genes is a rapid MAMP-triggered defense response, and suppression of genes involved in chromatin assembly and induction of ubiquitin-related genes coincide with pathogen-induced abscisic acid accumulation. Specific combinations of promoter motifs are engaged in fine-tuning the MTI response and active transcriptional suppression at specific promoter configurations by P. syringae.

“…As sessile organisms, plants have evolved many specific families of transcription factors that bind to the promoter regions of downstream genes and initiate their transcription (Shiu et al, 2005;Qu and Zhu, 2006;Yamasaki et al, 2013). Transcription regulators that do not bind DNA often work in concert with transcription factors via protein-protein interactions to fine-tune the regulatory machinery in response to surrounding environments, such as biotic stress and light stimuli (Wray et al, 2003;Yamaguchi-Shinozaki and Shinozaki, 2006;Jiao et al, 2007;Buscaill and Rivas 2014). A group of proteins designated as VQ motif-containing proteins (referred to here as VQ proteins) was recently identified (Xie et al, 2010;Cheng et al, 2012).…”

The VQ Motif-Containing Protein Family of Plant-Specific Transcriptional Regulators

ORCID IDs: 0000-0002-4772-7923 (Y.J.); 0000-0001-8346-3390 (R.L.).The VQ motif-containing proteins (designated as VQ proteins) are a class of plant-specific proteins with a conserved and single short FxxhVQxhTG amino acid sequence motif. VQ proteins regulate diverse developmental processes, including responses to biotic and abiotic stresses, seed development, and photomorphogenesis. In this Update, we summarize and discuss recent advances in our understanding of the regulation and function of VQ proteins and the role of the VQ motif in mediating transcriptional regulation and protein-protein interactions in signaling pathways. Based on the accumulated evidence, we propose a general mechanism of action for the VQ protein family, which likely defines a novel class of transcriptional regulators specific to plants.
