Abstract
Plant hormones auxin and cytokinin exert pleiotropic effects on growth and development, both individually and in a combinatorial manner. In recent years, our understanding of mechanisms of auxin and cytokinin action has improved considerably. This has largely been due to the molecular genetic analysis of hormone perception and signal transduction mutants of Arabidopsis, the model dicot plant, and also the availability of a high quality sequence of its 125 Mb genome. However, little work has been carried out in other plant species. Advances in genomics, particularly on rice, maize, sorghum and tomato, provide new opportunities for investigating these components in crop plants. A comparative analysis of Arabidopsis and rice genome sequences is already paying rich dividends and evolutionary relationship among various classes of gene families has been established, including those representing components of auxin and cytokinin signaling. Some of these auxin and cytokinin signaling components are proving to be invaluable genetic tools for manipulation of agronomic traits in crop plants, and it has been illustrated in this article with the help of a few suitable examples.
