“…Tan and Wu (2012) performed an in silico genome-wide assessment of NBS RGAs in brachypodium, identifying 239 NBS-encoding genes. Similarly, Tripathi et al (2012) performed in silico analysis of brachypodium WRKY transcription factors, known to possess critical roles in the modulation of numerous plant functions, including the response to biotic and abiotic stresses; the authors have developed a publicly accessible database for comparative analysis of these transcription factors. Such resources provide a useful platform for the selection of brachypodium genes to assess for roles in resistance to cereal diseases.…”

Background Cereal diseases cause tens of billions of dollars of losses annually and have devastating humanitarian consequences in the developing world. Increased understanding of the molecular basis of cereal host-pathogen interactions should facilitate development of novel resistance strategies. However, achieving this in most cereals can be challenging due to large and complex genomes, long generation times and large plant size, as well as quarantine and intellectual property issues that may constrain the development and use of community resources. Brachypodium distachyon (brachypodium) with its small, diploid and sequenced genome, short generation time, high transformability and rapidly expanding community resources is emerging as a tractable cereal model.Scope Recent research reviewed here has demonstrated that brachypodium is either susceptible or partially susceptible to many of the major cereal pathogens. Thus, the study of brachypodium-pathogen interactions appears to hold great potential to improve understanding of cereal disease resistance, and to guide approaches to enhance this resistance. This paper reviews brachypodium experimental pathosystems for the study of fungal, bacterial and viral cereal pathogens; the current status of the use of brachypodium for functional analysis of cereal disease resistance; and comparative genomic approaches undertaken using brachypodium to assist characterization of cereal resistance genes. Additionally, it explores future prospects for brachypodium as a model to study cereal-pathogen interactions.Conclusions The study of brachypodium-pathogen interactions appears to be a productive strategy for understanding mechanisms of disease resistance in cereal species. Knowledge obtained from this model interaction has strong potential to be exploited for crop improvement.

“…The first identified WRKY gene, SPF1, was cloned from sweet potato (Ipomoea batatas) 20 years ago [16]. Since then, a large number of WRKY genes have been identified, including 74 from Arabidopsis thaliana [17], 103 from Oryza sativa [18], 45 from Hordeum vulgare [19], 119 from Zea mays [20], and many more from other plant species [21][22][23].…”

Background: Sesame (Sesamum indicum L.) is one of the world's most important oil crops. However, it is susceptible to abiotic stresses in general, and to waterlogging and drought stresses in particular. The molecular mechanisms of abiotic stress tolerance in sesame have not yet been elucidated. The WRKY domain transcription factors play significant roles in plant growth, development, and responses to stresses. However, little is known about the number, location, structure, molecular phylogenetics, and expression of the WRKY genes in sesame.

“…However, compared to the knowledge on the role of WRKY TFs in plant responses to biotic stress, the information available on its role in plant responses to abiotic stress is still limited (Chen et al, 2012b;Rushton et al, 2010). An increasing number of reports show the potential of WRKY TFs as tools for engineering abiotic stress tolerance such as drought in plants (Chen et al, 2012b;Jiang et al, 2012;Rabara et al, 2013;Rushton et al, 2010;Tripathi et al, 2013). For example, constitutive expression of AtWRKY57 conferred drought tolerance in Arabidopsis ( Jiang et al, 2012).…”

Drought is one of the major constraints in crop production and has an effect on a global scale. In order to improve crop production, it is necessary to understand how plants respond to stress. A good understanding of regulatory mechanisms involved in plant responses during drought will enable researchers to explore and manipulate key regulatory points in order to enhance stress tolerance in crops. Transcription factors (TFs) have played an important role in crop improvement from the dawn of agriculture. TFs are therefore good candidates for genetic engineering to improve crop tolerance to drought because of their role as master regulators of clusters of genes. Many families of TFs, such as CCAAT, homeodomain, bHLH, NAC, AP2/ERF, bZIP, and WRKY have members that may have the potential to be tools for improving crop tolerance to drought. In this review, the roles of TFs as tools to improve drought tolerance in crops are discussed. The review also focuses on current strategies in the use of TFs, with emphasis on several major TF families in improving drought tolerance of major crops. Finally, many promising transgenic lines that may have improved drought responses have been poorly characterized and consequently their usefulness in the field is uncertain. New advances in high-throughput phenotyping, both greenhouse and field based, should facilitate improved phenomics of transgenic lines. Systems biology approaches should then define the underlying changes that result in higher yields under water stress conditions. These new technologies should help show whether manipulating TFs can have effects on yield under field conditions.
