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)
Cellular images obtained by light microscopy have been analyzed qualitatively, but there is still a lack of quantitative information about the variations in cellular metabolism of selective substances. A new approach using the multispectral imaging microscope (MIM) to observe rice (Oryza sativa L.) pollen grains is reported. A liquid crystal tunable filter(More)
Multispectral analysis combined with the Periodic Acid-Schiff method was used to investigate cytological features of insoluble polysaccharides and changes in total insoluble polysaccharide content (TPC) during pollen development in rice, including four cytoplasmic male sterility lines (MSLs) and their corresponding fertility-maintaining lines (FMLs). The(More)
