Book chapters:
Endogenous RNA constituents of the phloem and their possible roles in long-distance signaling
Research Areas
  • Molecular, cellular and genetic biology
This chapter provides an overview of experimental strategies that have been successfully employed to identify RNAs in sieve-tube sap and a summary of the different types of RNAs that have been identified. In addition, the methods to examine RNA mobility and potential physiological roles RNAs might play in the complex long-distance communication network of higher plants are discussed. Systemic RNA transport has been demonstrated through grafting experiments, transient gene expression movement assays, and parasitic plant interactions. The chapter focuses on the possible functions of RNAs for which phloem mobility has been demonstrated unequivocally. Assignment of functions for individual phloem-mobile RNAs will be essential to substantiate the hypothesis that specific RNAs indeed play essential roles in controlling and integrating diverse important physiological, developmental, and pathogenesis-related processes at the whole plant level.
