Formation of secondary wall requires coordinated transcrip- tional regulation of the genes involved in the biosynthesis of major secondary wall components （e.g. cellulose, hemicellu- lose, and lignin）. Even though many aspects of plant biology have been extensively elucidated using various model spe- cies, our current understanding of secondary wall formation is limited.

We report a case of duodenal varix bleeding as a long term complication of balloon occluded retrograde transvenous obliteration (BRTO), which was successfully treated with a transjugular intrahepatic portosystemic shunt (TIPS). A 57-year-old man was admitted to the emergency room suffering from melena. He had under-gone BRTO to treat gastric varix bleeding 5 mo before admission. Endoscopy and a computed tomography (CT) scan showed complete obliteration of the gastric varix, but the nodular varices in the second portion of the duodenum expanded after BRTO, and spurting blood was seen. TIPS was performed for treatment of duodenal variceal bleeding, because attempts at endoscopic varix ligation were unsuccessful. The post-operative course was uneventful and the patient was discharged without complications. A follow up CT scan obtained 21 mo after TIPS revealed a patent TIPS tract and complete obliteration of duodenal varices, but multinodular hepatocellular carcinoma had developed. He died of hepatic failure 28 mo after TIPS.

Color variation is a well-known feature of sea cucumbers （Apostichopus japonicus）, which are classified into three groups based on their colors of red, green and black. It is also one of the most important traits related to how they taste, and it thereby affects their market price. Attempts were made to identify single-nucleotide polymorphisms （SNPs） and to analyze differences associated with SNP genotypes between green and red color variants using HSP70 as the target gene. The HSP70 gene, which is found universally in organisms from bacteria to humans, is one of the most evolutionarily conserved genes and the most widely studied biomarker of stress response. DNA fragments of 1074 bp covering a partial sequence of the sea cucumber HSP70 gene, were amplified from both red and green variants, and subsequently analyzed for the presence of SNPs. Twenty-seven polymorphic sites in total, including heterozygous sites, were observed. Of these, six sites were found to be significantly different SNP genotypes between green and red variants. Furthermore, PCR with an internal primer designed to include an allelespecific SNP at the 3＇ end （site 443） showed differentiation between the two variants, 100% and 4.2% amplification in green and red variants, respectively. The validated SNPs may serve as informative genetic markers that can be used to distinguish variants at the early developmental stage, prior to color differentiation.

Soil salinity is one of the most serious agricultural problems that significantly reduce crop yields in the aridand semi-arid regions. It influences various phases of plant growth and developmental processes, such as seed germina-tion, leaf and stem growth, and reproductive propagation. Salt stress delays the onset of flowering in many plant spe-cies. We have previously reported that the Arabidopsis BROTHER OF FT AND TFL1 （BFT） acts as a floral repressor undersalt stress. However, the molecular mechanisms underlying the BFT function in the salt regulation of flowering inductionis unknown. In this work, we found that BFT delays flowering under high salinity by competing with FLOWERING LOCUST （FT） for binding to the FD transcription factor. The flowering time of FD-deficient fd-2 mutant was insensitive to highsalinity. BFT interacts with FD in the nucleus via the C-terminal domain of FD, which is also required for the interactionof FD with FT, and interferes with the FT-FD interaction. These observations indicate that BFT constitutes a distinct saltstress signaling pathway that modulates the function of the FT-FD module and possibly provides an adaptation strategythat fine-tunes photoperiodic flowering under high salinity.

Eu3＋-doped （Y,Gd）NbO4 phosphor was synthesized by solid-state reaction for possible application in cold cathode fluorescent lamps. A broad absorption band with peak maximum at 272 nm was observed which was due to the charge transfer between Eu3＋ ions and neighboring oxygen anions. A deep red emission at the peak wavelength of 612 nm was observed which could be attributed to the 5D0→7F2 transition in Eu3＋ ions. The highest luminance for Y1-x-yGdyNbO4：Eux3＋ under 254 nm excitation was achieved at Eu3＋ concentration of 18 mol.% （x=0.18） and Gd3＋ concentration of 8.2 mol.% （y=0.082）. The luminance of Y0.738Gd0.082NbO4：Eu3＋0.18 was higher than that of a typical commercial phosphor Y2O3：Eu3＋ and the CIE chromaticity coordinate was （0.6490, 0.3506）, which was deeper than that of Y2O3：Eu3＋. The particle size of the synthesized phosphors was controlled by the NaCl flux and particle size as high as 8 μm with uniform size distribution of particles was obtained.
