Suaeda japonica Makino, a succulent euhalophyte from the Chenopodiaceae family, grows naturally in Japan and is presumed to exhibit high salt tolerance. However, the molecular mechanisms underlying its salinity tolerance remain poorly understood. This study aimed to examine the physiological responses of S. japonica to varying NaCl concentrations, perform transcriptome profiling of its leaves and roots under 600 mM NaCl exposu...
Stenotrophomonas sp. strain CK1 volatile organic compounds improved rice growth under saline conditionsNARA Subscribed
Plant-bacteria indirect interaction is a naturally occurring phenomenon however many aspects of this interaction remain unclear. In this study, the effects of bacterial inoculation were investigated by tissue culture experiments as indirect application to compare rice growth in saline conditions. Four isolates applied indirectly had 1.5-times greater shoot dry mass of rice under 100 mM NaCl treatment. The isolates were identif...
The behavioural homing response of adult chum salmon Oncorhynchus keta to amino‐acid profilesNARA Subscribed
Adult chum salmon Oncorhynchus keta homing behaviour in a two‐choice test tank (Y‐maze) was monitored using a passive integrated transponder (PIT)‐tag system in response to river‐specific dissolved free amino‐acid ( DFAA ) profiles and revealed that the majority of O. keta showed a preference for artificial natal‐stream water and tended to stay in this maze arm for a longer period; natal‐stream water was chosen over a nearby t...
The effects of external and surgically implanted radio transmitters on juvenile masu salmon Oncorhynchus masou were examined. External attachment of transmitters significantly decreased the survival of fish and caused a decreased critical swimming speed compared with surgical implantation. Although plasma cortisol, plasma glucose and haematocrit values did not differ significantly among groups, it appeared that the most suitab...
Migratory behaviour of adult chum salmon, Oncorhynchus keta , in a reconstructed reach of the Shibetsu River, JapanNARA Subscribed
During 2004–2006, 30 adult chum salmon, Oncorhynchus keta (Walbaum), were tagged with electromyogram (EMG) transmitters and depth/temperature loggers and tracked along both the channelised and reconstructed segments of the Shibetsu River, Japan to assess the effects of the river re‐meandering construction on upstream migration. Holding time of chum salmon in the reconstructed segment was longer than in the channelised segment....
