WRKY transcription factors are crucial regulatory components of plant responses to pathogen infection. In the present study, we report isolation and functional characterization of the pathogen-responsive rice WRKY30 gene, whose transcripts accumulate rapidly in response to salicylic acid (SA) and jasmonic acid (JA) treatment. Overexpression of WRKY30 in(More)
WRKY transcription factors have been implicated in the regulation of transcriptional reprogramming associated with various plant processes but most notably with plant defense responses to pathogens. Here we demonstrate that expression of rice WRKY4 gene (OsWRKY4) was rapidly and strongly induced upon infection of Rhizoctonia solani, the causing agent of(More)
Plant WRKY transcription factors play pivotal roles in diverse biological processes but most notably in plant defense response to pathogens. Sheath blight represents one of the predominant diseases in rice. However, our knowledge about the functions of WRKY proteins in rice defense against sheath blight is rather limited. Here we demonstrate that the(More)
Lightness illusions, such as the seemingly opposing effects of brightness contrast and assimilation, are characterized by visually perceived intensity images that differ from physical reality. Traditional hypotheses from signal processing community primarily use filtering to explain these phenomena. However, these methods may fail due to the change in(More)
