Abstract Potato (Solanum tuberosum) is relatively vulnerable to abiotic stress conditions such as drought, but the tolerance mechanisms for stresses in potato are largely unknown. To identify stress-related factors potato, we previously carried out a genetic screen of plants exposed environmental using reverse northern-blot analysis. A cDNA encoding putative R1-type MYB-like transcription factor (StMYB1R-1) was identified stress-response gene. Here, transcript levels StMYB1R-1 were enhanced...
Summary WRKY proteins are transcription factors ( TF s) that regulate the expression of defense‐related genes. The salicylic acid SA )‐inducible Oryza sativa WRKY6 (OsWRKY6) was identified as a positive regulator pathogenesis‐related 10a OsPR10a ) by transient assays. A physical interaction between Os 6 and W‐box‐like element 1 WLE 1), which positively regulates PR 10a/ probenazole induced protein expression, verified in vitro . Several genes were constitutively activated, including ,...
Plants are frequently subjected to abiotic and biotic stresses, WRKY proteins play a pivotal role in the response such stress. OsWRKY11 is induced by pathogens, drought, heat, suggesting function stress responses.This study identified OsWRKY11, member of group IIc. It transcriptional activator that localized nucleus. Ectopic expression resulted enhanced resistance bacterial pathogen, Xanthomonas oryzae pv. oryzae; was compromised transgenic lines under-expressing OsWRKY11. constitutive...
Mutating transcription factor genes involved in growth, development, and stress response rice enhances disease resistance to microbial pathogens without suffering a yield penalty.
WRKY proteins play essential roles as negative or positive regulators of pathogen defense. This study explored the different OsWRKY in basal defense and Xa1-mediated resistance to Xanthomonas oryzae pv. (Xoo) infection rice. Assays disease OsWRKY10KD OsWRKY88KD lines following with an incompatible Xoo race, which induced wild-type plants, showed that OsWRKY10 OsWRKY88 were resistance. also acted a regulator by directly indirectly activating transcription defense-related genes. activated...
The WRKY family of transcription factors plays a pivotal role in plant responses to biotic and abiotic stress. Group III factor OsWRKY114 is positive regulator innate immunity against Xanthomonas oryzae pv. oryzae; however, its stress largely unknown. In this study, we showed that the abundant transcripts present transgenic rice plants are reduced under drought conditions. overexpression significantly increased sensitivity rice, which resulted lower survival rate after Moreover, stomatal...
Results from clinical studies have demonstrated that inhibitors of histone deacetylase (HDAC) enzymes possess promise for the treatment several types cancer. Zolinza® (widely known as SAHA) has been approved by FDA T-cell lymphoma. As a continuity our ongoing research to find novel small molecules target these important enzymes, we synthesized series benzothiazole-containing analogues SAHA and found compounds with very potent anticancer cytotoxicity. In this study, three more type, including...
Diverse bacterial and fungal pathogens attack plants, causing biotic stress severe yield losses globally. These are expected to become more serious as climate change improves conditions for many pathogens. Therefore, identifying genes conferring broad-spectrum disease resistance elucidating their underlying mechanisms provides important resources plant breeding. WRKY transcription factors affect growth responses. However, the functions of proteins remain be elucidated. Here, we demonstrated...
WRKY transcription factors (TFs) are involved in regulating a range of biological processes such as growth, development, and the responses to biotic abiotic stresses. Genome-wide expression profiling OsWRKY TF superfamily genes rice after infection with Xanthomonas oryzae pv. (Xoo) was performed elucidate function TFs interaction between Xoo. Of 111 tested, 94 changed Xoo infection. The were classified into eight types according their profiles. Eighty-two Groups I, II, III, IV, VII...
Bacterial blight in rice caused by Xanthomonas oryzae pv. (Xoo) greatly reduces the growth and productivity of this important food crop. Therefore, we sought to increase resistance bacterial using a NAC (NAM, ATAF, CUC) transcription factor, one plant-specific factors that is known be involved biotic/abiotic stress resistance. By isolating OsNAC58 gene from analyzing its biological functions related Xoo resistance, phylogenetic analysis showed belongs group III. To investigate relationship...
