| heterologous expression of a plant rela-spot homologue results in increased stress tolerance in saccharomyces cerevisiae by accumulation of the bacterial alarmone ppgpp. | the bacterial alarmone ppgpp is present only in bacteria and the chloroplasts of plants, but not in mammalian cells or eukaryotic micro-organisms such as yeasts and fungi. the importance of the ppgpp signalling system in eukaryotes has therefore been largely overlooked. here, we demonstrated that heterologous expression of a rela-spot homologue (sj-rsh) isolated from the halophilic plant suaeda japonica in the yeast saccharomyces cerevisiae results in accumulation of ppgpp, accompanied by enhanc ... | 2012 | 22679107 |
| marinobacterium rhizophilum sp. nov., isolated from the rhizosphere of the coastal tidal-flat plant suaeda japonica. | a gram-negative, strictly aerobic, marine bacterium, designated strain cl-yj9(t), was isolated from sediment closely associated with the roots of a plant (suaeda japonica) inhabiting a coastal tidal flat. cells of the novel strain were straight and rod-shaped and were motile by means of monopolar flagella. a phylogenetic analysis based on 16s rrna gene sequences revealed that strain cl-yj9(t) belongs to the genus marinobacterium and was most closely related to marinobacterium halophilum mano11(t ... | 2008 | 18175703 |
| plant rela/spot homolog confers salt tolerance in escherichia coli and saccharomyces cerevisiae. | to analyze the mechanisms of salt tolerance in the halophyte suaeda japonica, escherichia coli was used as a host organism to undertake functional screening of cdnas encoding proteins that may play an important role for the salt-tolerance mechanisms. a transformant expressing rela/spot homolog (sj-rsh) was found to have enhanced salt tolerance. in e. coli, rela/spot controlled the amount of guanosine tetraphosphate (ppgpp) and guanosine pentaphosphate (pppgpp), which are the effectors of the bac ... | 2003 | 12552141 |
| rhodochlanis suaedicola sp. nov. (hemiptera: sternorrhyncha: psylloidea: aphalaridae) associated with suaeda japonica (amaranthaceae) from korea. | a new psyllid species, rhodochlanis suaedicola sp. nov., is described and illustrated from korea based on adults and fifth instar immatures. rhodochlanis is reported for the first time from korea. the new species is associated with suaeda japonica (amaranthaceae) growing in saline habitats. salt marshes in korea are threatened by sea side developments. it is suggested that these habitats should be protected to ensure the survival of r. suaedicola. | 2015 | 26624316 |
| fungal diversity and plant growth promotion of endophytic fungi from six halophytes in suncheon bay. | endophytic fungi were isolated from roots of six halophytes in suncheon bay. the endophytic fungi of 35 species isolated from halophytes were identified by internal transcribed spacer (its) containing the its1, 5.8s, and its2 regions. all fungal strains were analyzed to diversity at the genus level. fungal culture filtrates (fcf) of endophytic fungi were treated to waito-c rice (wr) seedling for plant growth-promoting verification. it was confirmed that fungal strain sj-2-2 provided plant growth ... | 2012 | 23124347 |
