The Queen of the Night arrives in Tucson! This is a photograph of the night-blooming Cereus (Peniocereus greggii) that I captured on June 20th, 2007. What is so special about this cactus? Well, this plant blooms only once every year and it does so only in the night!! For the remaining 364 days, this Cereus…Continue Reading Image of the month (July 2007)
This image took the honors from Nature Cell Biology when they featured Arabidopsis trichome as the cell of the month in 2004 ( Nature Cell Biology 6, 707 (2004) ). In the issue that honored this image, the following was the text that accompanied the image: “The image shows a plant hair cell (trichome) on a…Continue Reading Image of the month (January 2007)
This is a Scanning Electron Micrograph of a germinating Arum or Voodo Lily (Sauromatum guttatum). This image shows the size of the pollen after it was magnified 435 times. This image is one of the many elegant images from the Dennis Kunkel Microscopy collection. The elegance, breathtaking beauty, and less-intrusive false coloring aspects helped make this our…Continue Reading Image of the month (May 2007)
This image is from a figure in a research article by Reddy & Meyerowitz 2005. (A related article is our featured paper of the month in October). This image is a reconstructed view of the L1 layer of the shoot apical meristems (SAM)s. To study the immediate effect of loss of CLV3 function, the authors utilized dex-inducible clv3 RNAi…Continue Reading Image of the month (October 2006)
This image is from a figure in a research article by Nowack et al 2006. (This article is also our featured paper of the month in August). This is a DAPI-stained image of an Arabidopsis thaliana pollen. DAPI staining of a pollen grain reveals a diffused body (vegetative nucleus) and a highly condensed body (generative nucleus) within a pollen grain. This figure…Continue Reading Image of the month (August 2006)
This is a confocal image of an Arabidopsis thaliana cell. This image is from the cover of the Plant Journal June 1999 issue, showcasing a representative figure from a paper that appeared in that issue: Kandasamy et al (1999) Plant Journal 18: 681-691. The text that accompanied the cover succinctly provides both background and explanation for this image….Continue Reading Image of the month (June 2006)
This is a confocal image of an Arabidopsis thaliana ovule. This image is from Fig. 3, Kasahara et al (2005) Plant Cell 17: 2981-2992. In this paper, the authors report the functions of an A. thaliana gene, MYB98. To determine which cells within the female gametophyte expressed MYB98, they generated and analyzed transgenic A. thaliana plants containing ProMYB98:green fluorescent protein (GFP) constructs….Continue Reading Image of the Month (May 2006)
