WRKY transcription factors play important roles in the regulation of biotic and abiotic stresses. Here, we report a group I WRKY gene from Polygonum cuspidatum, PcWRKY33, that encodes a nucleoprotein, which specifically binds to the W-box in the promoter of target genes to regulate their expression.

Plants are affected by many environmental factors during their various stages of growth, among which salt stress is a key factor. WRKY transcription factors play important roles in the response to

In this study, one novel group IIc WRKY transcription factor named HbWRKY82 was identified and characterized as a stress-associated WRKY in rubber tree. Transient expression and transcriptional activation analyses indicated that HbWRKY82 encoded a nuclear protein and functioned as a transcription activator.

Being one of the largest families of transcriptional regulators in plants, WRKY transcription factors (TFs) have been suggested to play significant roles in regulation of various abiotic and biotic stress responses and several developmental and physiological processes. Modification and analyses of its expression patterns contribute to the elaboration of the WRKY proteins comprise a large family of transcription factors. Despite their dramatic diversification in plants, WRKY genes seem to have originated in early eukaryotes. The cognate DNA-binding site of WRKY factors is well defined, but determining the roles of individual family members in regulating specific transcriptional programs during development or in Abstract The WRKY transcription factor family has 109 members in the rice genome, and has been reported to be involved in the regulation of biotic and abiotic stress in plants. Here, we demonstrated that a rice OsWRKY74 belonging to group III of the WRKY transcription factor family was involved in tolerance to phosphate (Pi) starvation.

Plants are subject to attack by diverse pests and pathogens. Few genes conferring broad-spectrum resistance to both insects and pathogens have been identified. Because of the growth-defense tradeoff, it is often challenging to balance biotic stress resistance and yield for crops.

WRKY transcription factors are one of the largest families of transcriptional regulators in plants and form integral parts of signalling webs that modulate many plant processes. Here, we review recent significant progress in WRKY transcription factor research. New findings illustrate that WRKY proteins often act as repressors as well as activators, and Key message WRKY transcription factors are among the largest families of transcriptional regulators. In this review, their pivotal role in modulating various signal transduction pathways during biotic and abiotic stresses is discussed.

Objective In silico identification and characterization of WRKY transcription factor-encoding genes in chickpea genome. Methods For this purpose, a systematic genome-wide analysis was carried out to identify the non-redundant WRKY transcription factors in the chickpea genome. Results WRKY transcription factors can regulate plant hormone signal transduction pathways during the stress response, and can also activate or inhibit the expression of downstream genes through binding to the W-box motif [11]. Overexpression of some WRKY genes altered the protective effect of the SA and JA pathways. WRKY transcription factors are one of the important families in plants, and have important roles in plant growth, abiotic stress responses, and defense regulation.
