WRKY transcription factors belong to one of the largest transcription factor families. These factors possess functions in plant growth and development, signal transduction, and stress response. Here, we identified 95 DcWRKY genes in carrot based on the carrot genomic and transcriptomic data, and divided them into three groups. Phylogenetic analysis of WRKY proteins from carrot and Arabidopsis d...

Snapdragon (Antirrhinum majus) is one of the most widely cultivated grass flowers in world. WRKY transcription factors, VQ proteins and their interactions play crucial roles plant response to abiotic stresses. However, little known about gene families snapdragon. In present study, genes were comprehensively analyzed snapdragon using bioinformatics approaches, expression drought cold stresses wa...

WRKY proteins comprise a large family of transcription factors that play important roles in plant defence regulatory networks, including responses to various biotic and abiotic stresses. To date, no large-scale study of WRKY genes has been undertaken in grape (Vitis vinifera L.). In this study, a total of 59 putative grape WRKY genes (VvWRKY) were identified and renamed on the basis of their re...

The WRKY gene family plays an important role in the development and stress responses in plants. As information is not available on the WRKY gene family in Musa species, genome-wide analysis has been carried out in this study using available genomic information from two species, Musa acuminata and Musa balbisiana. Analysis identified 147 and 132 members of the WRKY gene family in M. acuminata an...

The WRKY gene family is among the largest families of transcription factors (TFs) in higher plants. By regulating the plant hormone signal transduction pathway, these TFs play critical roles in some plant processes in response to biotic and abiotic stress. Various bodies of research have demonstrated the important biological functions of WRKY TFs in plant response to different kinds of biotic a...

As a superfamily of transcription factors, the tryptophan-arginine-lysine-tyrosine (WRKY) transcription factors have been found to be essential for abiotic and biotic stress responses in plants. Currently, only 76 WRKY transcription factors in wheat could be identified in the NCBI database, among which only a few have been functionally analyzed. Herein, a total of 188 WRKY transcription factors...

WRKY transcription factor is involved in multiple life activities including plant growth and development as well as biotic and abiotic responses. We identified 28 WRKY genes from transcriptome data of Ginkgo biloba according to conserved WRKY domains and zinc finger structure and selected three WRKY genes, which are GbWRKY2, GbWRKY16, and GbWRKY21, for expression pattern analysis. GbWRKY2 was p...

WRKY transcription factors constitute a large protein family in plants that is involved in the regulation of developmental processes and responses to biotic or abiotic stimuli. The question arises how stimulus-specific responses are mediated given that the highly conserved WRKY DNA-binding domain (DBD) exclusively recognizes the 'TTGACY' W-box consensus. We speculated that the W-box consensus m...

One of the fundamental behaviors of plants, being sessile allows them to develop an intricate molecular machinery to adapt themselves to biotic and abiotic challenges experienced in the environment. In response to adapt against a particular stress, a massive transcriptional activity of several genes triggered the defense responses in the plant cell. Extensive research on stress related studies ...

Many biological processes are controlled by intricate networks of transcriptional regulators. With the development of microarray technology, transcriptional changes can be examined at the whole-genome level. However, such analysis often lacks information on the hierarchical relationship between components of a given system. Systemic acquired resistance (SAR) is an inducible plant defense respon...
