Gene transcription in the leaves of rice undergoing salt-induced morphological changes (Oryza sativa L.).
We describe the gene expression profile of third leaves of rice (cv. Nipponbare) seedlings subjected to salt stress (130 mM NaCl). Transcripts of Mn-SOD, Cu/Zn-SOD,cytosolic and stromal APX, GR andExpand

Effects of pH and Osmotic Stress on Cellular Polyamine Contents in the Soybean Rhizobia Rhizobium fredii P220 and Bradyrhizobium japonicum A1017.
Homospermidine is a polyamine present in its highest concentrations in root nodule bacteria. By using the soybean rhizobia Rhizobium fredii P220 and Bradyrhizobium japonicum A1017, the effects of theExpand

Root-nodule bacteria (rhizobia) are of great importance for nitrogen acquisition through symbiotic nitrogen fixation in a wide variety of leguminous plants. These bacteria differ from most other soilExpand

Shoot-applied polyamines suppress nodule formation in soybean (Glycine max).
In legumes, the number of root nodules is controlled by a mechanism called autoregulation. Recently, we found that the foliar brassinosteroid (BR), a plant growth-regulating hormone, systemicallyExpand

Possible contribution of Bradyrhizobium on nitrogen fixation in sweet potatoes
AimsSweet potato (Ipomoea batatas) is known for its ability to grow under nitrogen-limited conditions. To clarify the possible contribution of biological nitrogen fixation, we tried to isolate andExpand

Induction of class-1 non-symbiotic hemoglobin genes by nitrate, nitrite and nitric oxide in cultured rice cells.
Non-symbiotic hemoglobins (ns-Hbs) are found in all plants, although their physiological function remains to be determined. The present study was undertaken to explore the mode of induction of ns-HbExpand

Systemic Effect of a Brassinosteroid on Root Nodule Formation in Soybean as Revealed by the Application of Brassinolide and Brassinazole
Leguminous plants form nitrogen-fixing root nodules and the number of nodules is controlled by a self-regulating mechanism called autoregulation. However, signaling substances involved in noduleExpand

Free polyamine concentrations in coastal seawater during phytoplankton bloom
SUMMARY: Polyamines are widely distributed in nature and known to have many roles in living organisms. We investigated the concentrations of polyamines together with inorganic nutrients during aExpand
