Abstract
Summary:With the completion of the rice genome sequencing project, the next major challenge is the systematic determination of gene function, then difficulties arise in the identification of a phenotype quantitatively that can be associated with the mutation. Here we overview the trend in image technology and its application for the phenotypic analysis process. We introduce our attempts to measure various parameters based on a series of growth images collected by newly developed automatic imaging system. First, the detailed measurement of leaf length in rice seedlings was carried out and presented. Second, the rice lamina inclination process was continuously analyzed and the effects of plant hormone and light on this response were discussed. Third, the leaf area of Arabidopsis thaliana was continuously measured, and a circadian rhythm of leaf movements was identified. We would like to discuss future aspects of image analysis and related technology for a complete understanding of a gene's function that will be realized only when genomic information can be associated with a phenotype at the organismal level.
