A Systemic Small RNA Signaling System in Plants

From: Plant Cell | Date: August 1, 2004| Author: Et al; Haywood, Valerie; Kragler, Friedrich; Varkonyi-Gasic, Erika; Yoo, Byung-Chun | Copyright information

Systemic translocation of RNA exerts non-cell-autonomous control over plant development and defense. Long-distance delivery of mRNA has been proven, but transport of small interfering RNA and microRNA remains to be demonstrated. Analyses performed on phloem sap collected from a range of plants identified populations of small RNA species. The dynamic nature of this population was reflected in its response to growth conditions and viral infection. The authenticity of these phloem small RNA mole...

Water relations link carbon and oxygen isotope discrimination to phloem sap sugar concentration in Eucalyptus globulus
Plant Physiology ; A strong correlation was previously observed between carbon isotope discrimination ([Delta]^sup 13^C) of phloem sap sugars and phloem sap sugar concentration in the phloem-bleeding tree Eucalyptus globulus Labill. (J. Pate, E. Shedley, D. Arthur, M. Adams [1998] Oecologia 117: 312-322). We
A Diurnal Component to the Variation in Sieve Tube Amino Acid Content in Wheat1[OA]
Plant Physiology ; We have used high-sensitivity capillary electrophoresis coupled to a laser-induced fluorescence detection method to quantify 16 amino acids in wheat (Triticum aestivum) sieve tube (ST) samples as small as 2 nL collected by severing the stylets of feeding aphids. The sensitivity of the method was
The dual function of sugar carriers: Transport and sugar sensing
Plant Cell ; INTRODUCTION Sucrose and its derivatives represent the major transport forms of photosynthetically assimilated carbon in plants. Sucrose synthesized in green leaves is exported via the phloem, the long-distance distribution network for assimilates, to supply nonphotosynthetic organs with energy and
siRNA and miRNA isolation.(Focus)
Bioscience Technology ; Traditional mRNA isolation procedures were developed to efficiently recover mRNA, and can result in the loss of substantial amounts of small RNAs. The proprietary mirVana[TM] miRNA Isolation Kit purifies all RNA species, including small RNAs, both single- and double-stranded. Through an enrichment
Host-plant flowering status and the concentration of sugar in phloem sap: Effects on an ant-treehopper interaction
European Journal of Entomology ; Keywords. Ant-treehopper association, honeydew, host-plant mediation, host-plant quality, Membracidae, mutualism, phloem sugar, tritrophic interaction, cerrado savanna Abstract. Host-plant mediation in ant-hemipteran mutualisms requires three conditions. First, hemipteran attractiveness to ants
Salicylic Acid, an Ambimobile Molecule Exhibiting a High Ability to Accumulate in the Phloem1
Plant Physiology ; The ability of exogenous salicylic acid (SA) to accumulate in castor bean (Ricinus communis) phloem was evaluated by HPLC and liquid scintillation spectrometry analyses of phloem sap collected from the severed apical part of seedlings. Time-course experiments indicated that SA was transported to
Herbivore-Induced Callose Deposition on the Sieve Plates of Rice: An Important Mechanism for Host Resistance1[W][OA]
Plant Physiology ; The brown planthopper (Nilaparvata lugens Stal; BPH) is a specialist herbivore on rice (Oryza sativa) that ingests phloem sap from the plant through its stylet mouthparts. Electronic penetration graphs revealed that BPH insects spent more time wandering over plants carrying the resistance genes
Destination-Selective Long-Distance Movement of Phloem Proteins(W)
Plant Cell ; The phloem macromolecular transport system plays a pivotal role in plant growth and development. However, little information is available regarding whether the long-distance trafficking of macromolecules is a controlled process or passive movement. Here, we demonstrate the destination-selective
Differential Regulation of Sorbitol and Sucrose Loading into the Phloem of Plantago major in Response to Salt Stress1[OA]
Plant Physiology ; Several plant families generate polyols, the reduced form of monosaccharides, as one of their primary photosynthetic products. Together with sucrose (Suc) or raffinose, these polyols are used for long-distance allocation of photosynthetically fixed carbon in the phloem. Many species from these
FLOWERING LOCUS T Protein May Act as the Long-Distance Florigenic Signal in the Cucurbits(W)
Plant Cell ; Cucurbits moschata, a cucurbit species responsive to inductive short-day (SD) photoperiods, and Zucchini yellow mosaic virus (ZYMV) were used to test whether long-distance movement of FLOWERING LOCUS T (FT) mRNA or FT is required for floral induction. Ectopic expression of FT by ZYMV was highly
