Analysis of the distribution of assimilation products and the characteristics of transcriptomes in rice by submergence during the ripening stage.

Background: Research on the submergence stress of rice has concentrated on the quiescence strategy to survive in long-term flooding conditions based on Submergence-1A (SUB1A). In the case of the ripening period, it is important that submergence stress can affect the quality as well as the survival of rice. Therefore, it is essential to understand the changes in the distribution of assimilation products in grain and ripening characteristics in submergence stress conditions.

Upregulation of Connexin 43 Expression Via C-Jun N-Terminal Kinase Signaling in Prion Disease.

Prion infection leads to neuronal cell death, glial cell activation, and the accumulation of misfolded prion proteins. However, the altered cellular environments in animals with prion diseases are poorly understood. In the central nervous system, cells connect the cytoplasm of adjacent cells via connexin (Cx)-assembled gap junction channels to allow the direct exchange of small molecules, including ions, neurotransmitters, and signaling molecules, which regulate the activities of the connected cells.

Sooty Mould Disease Caused by Leptoxyphium kurandae on Kenaf.

In September 2013, we discovered sooty mould growing on kenaf with the extrafloral nectaries in Iksan, Korea and identified the causative fungus as Leptoxyphium kurandae based on morphological characteristics and phylogenetic analyses. This is the first report of sooty mould caused by L. kurandae on kenaf in Korea and globally.

Decomposition reaction of the veterinary antibiotic ciprofloxacin using electron ionizing energy.

The application of electron ionizing energy for degrading veterinary antibiotic ciprofloxacin (CFX) in aqueous solution was elucidated. The degradation efficiency of CFX after irradiation with electron ionizing energy was 38% at 1 kGy, 80% at 5kGy, and 97% at 10 kGy. Total organic carbon of CFX in aqueous solution after irradiation with electron ionizing energy decreased 2% at 1 kGy, 18% at 5 kGy, and 53% at 10 kGy.

Female sex pheromone of the Gelechiid moth Scrobipalpa salinella (Zeller).

The sex pheromone system of Scrobipalpa salinella (Zeller), an important pest of the halophyte Salicornia europaea in the tidal salt marshes, was studied. Z3-12:OAc and Z5-12:OAc were identified from both female pheromone glands and female emissions, but in quite different ratios. Field trapping tests demonstrated that Z3-12:OAc and Z5-12:OAc are essential for optimal attraction of male moths, and a 100:5 blend found in gland extracts is significantly more attractive to males than a 100:50 ratio similar to that found in SPME samples.
