Dhaka the 8th Feb. ’14. In an article titled, “The Role of Target of Rapamycin Signaling Networks in Plant Growth and Metabolism.” published in the February, ’14 issue of Plant Physiology, Yan Xiong and Jen Sheen describe the target of rapamycin (TOR) kinase. It is a master regulator conserved among yeasts (Saccharomyces cerevisiae),plants, animals, and humans, signaling the nutrient and energy to promote cell proliferation and growth. Recently, there have been breakthroughs in which chemical, genetic, and genomic analyses have been integrated. Such comprehensive study encompassing a number of related areas has greatly increased our understanding of the molecular functions and dynamic regulation of the TOR kinase in photosynthetic plants. Furthermore, TOR signaling plays fundamental roles in a number of growth and developmental processes such as embryogenesis, meristem activation, root and leaf growth, flowering, senescence, and establishment of life span. An intensive study on TOR has revealed that it coordinates unique transcriptional networks involving central metabolism and biosynthesis for energy and biomass production.
