“…On the other hand, the expression of the barley HvWRKY38 in Paspalum notatum Flugge increased the drought tolerance of the transgenic plants (Xiong et al 2010). Similar results were obtained when the Glycine Soja GsWRKY20 was expressed in Arabidopsis (Luo et al 2013) and the maize ZmWRKY58 was overexpressed in transgenic rice (Cai et al 2014). In rice, the overexpression of OsWRKY7 (Ramamoorthy et al 2008), OsWRKY05, OsWRKY43, OsWRKY1, OsWRKT2 (Berri et al 2009) and OsWRKY11 ) was shown to improved drought tolerance.…”

“…Our previous study revealed that the possible involvement of the transcription factor OsERF1 in the JA/ET induction of RSOsPR10 (Takeuchi et al 2011). Recently overexpression of a maize WRKY58 transcription factor was reported to be involved in enhancement of drought and salt tolerance in transgenic rice (Cai et al 2014). Further studies should attempt to clarify the mechanisms of stress and root specific RSOsPR10 expression in transcriptional levels.…”

RSOsPR10 was originally identified as a rice root-specific pathogenesis-related protein whose production was induced by drought and salinity stresses, but not by low temperature or abscisic acid. Our previous studies revealed that RSOsPR10 expression is up-regulated by jasmonic acid, and strongly inhibited by salicylic acid. Immunohistochemical experiments indicated RSOsPR10 is expressed in the root cortical cells. In the present study, we generated RSOsPR10-overexpressing lines of rice and bentgrass to examine the physiological roles of RSOsPR10 in plants. RSOsPR10-overexpressing rice plants were highly tolerant against drought stress, but not against salinity. In contrast, RSOsPR10-overexpressing bentgrass plants were tolerant against drought and salinity stresses. There was little difference between transgenic and wildtype plants regarding phenotype or above-ground growth rates. However, the root mass of the transgenic rice and bentgrass plants was significantly greater than that of the wild-type plants. Therefore, RSOsPR10 is likely involved in mediating environmental stress tolerance through an increase in root growth and development.

“…AtWRKY57 conferring drought tolerance by elevated ABA levels was reported [35]. A group II WRKY TF named WRKY58 was characterized from maize enhancing the tolerance towards drought and salt stress [36]. There are reports that few WRKY genes can be induced by both biotic and abiotic stress conditions.…”

Drought and salt stress are two major environmental constraints that limit the productivity of agriculture crops worldwide. WRKY transcription factors are the plantspecific transcription factors that regulate several developmental events and stress responses in plants. The WRKY domain is defined by a 60-amino acid conserved sequence named WRKYGQK at N-terminal and a Zinc Finger-like motif at the Cterminal. WRKY genes are known to respond several stresses which may act as negative or positive regulators. The function of most of the WRKY transcription factors from non-model plants remains poorly understood. This investigation shows the expression levels of eight WRKY transcription factor genes from horsegram plant under drought and salt stress conditions. The increase in mRNA transcript levels of WRKY transcription factor genes was found to be high in drought stressed plants compared to salt-stressed plants. The levels of MDA which indicates the lipid peroxidation were less in drought stress. More ROS is produced in salt stress conditions compared to drought. The results show that the expression of WRKY transcription factors in drought stress conditions is reducing the adverse effect of stress on plants. These results also suggest that, during abiotic stress conditions such as drought and salt stress, WRKY transcription factors are regulated at the transcription level.
