Fruit quality traits like heat, color and flavor are unique and important for pepper cuisines and industrial use. Pepper pigments include chlorophyll, carotenoids, anthocyanin and red pigments like capsanthin are unique carotenoids to capsicum spp. So developing carotenoids-rich peppers and use of red pigments extraction along with capsaicinoids are one of interest pepper breeding goals in the world. Horticultural traits of 113 germplasms introduced by international cooperative research with YASS of China were evaluated to select promissing materials for high quality peppers during the past 3 years. All of germplasms including 60 local peppers were belong to C. annuum and fruit characteristics were diverse. Especially fruit chemical compositions like ASTA color, capsaicinoids and sugars were evaluated compared with korean commercial peppers. Average contents of ASTA color was 98±37, 55±63mg in capsaicinoids and 12±6% in total sugars. ASTA color which generally means red pigments content was over 120 in 25 germplasms including over 200 in 2 germplasms. Higher ASTA colors were observed in different fruit types. Capsaicinoids content was over 90mg/100g in 24 germplasms including 5 germpalsms over 200mg. Especially higher capsaicinoids were higher in local peppers with round and wrinkled fruit shape. And total sugar content was over 20% in 10 germplasms. Germplasms of different fruit shapes and characteristics will be useful materials for diverse fruit quality breeding.

Zhong Yun Piao,Su Ryun Choi,Young Mi Lee,Hong Gi Kim,Yong Pyo Lim 한국원예학회 2007 Horticulture, Environment, and Biotechnology Vol.48 No.3
Chinese cabbage cultivated in most area of Korea is subjected to the most serious clubroot disease caused by Plasmodiophora brassicae Wor. A number of clubroot resistant (CR) cultivars were released or in development. We have previously tagged CR locus (CRb) within 3 cM flanked by two co-dominant markers (TCR01 and TCR05) and one dominant marker (TCR09). Thirty-seven CR cultivars and ten non-CR cultivars were collected to study the utility of these DNA markers. In addition, markers (BRMS096, BRMS088, and OPC11-2S) linked to Crr1, Crr2, and Crr3, respectively, were evaluated. Of the surveyed CR cultivars, 18 carried marker fragment TCR01₂?? and TCR05₂?? linked to CRb in coupling. Evaluation of these cultivars to race 4 of clubroot revealed that all of them conferred resistance. Other CR cultivars absent of TCR01₂?? and TCR05₂?? were either resistant or susceptible. Only OPC11-2S linked to Crr3 can explain the two CR cultivars showing susceptible, while others cannot. Analysis of European Clubroot Differential set 01 to 04 indicate that marker fragment TCR05₂?? with the CRb locus, possibly also TCR01₂??, was introgressed from CR turnip into partial CR cultivars of Chinese cabbage. The usefulness of these markers in marker-assisted selection was also discussed.

Herbaceous model species, especially Arabidopsis has provided a wealth of information about the genes involved in floral induction and development of inflorescences and flowers. While the genus Populus is an important model system for the molecular biology of woody plant. These two genuses differ in many ways. This study was designed to improve understanding of flower development in poplar at a system level, as its regulatory pathway to a large extent remains poorly known, owing to the presently limited mutant pool. To address this issue, a poplar GeneChip was employed to detect genes expressed during the whole floral developmental process. Using the expressed floral genes, a systematic gene network was constructed with the aid of functional association with Arabidopsis. The results suggested that autonomous, gibberellin, vernalization, photoperiod, ethylene, brassinosteroid, stress-induced and floral suppression pathways are involved in poplar flowering. Modularity analysis revealed several pathways in common with Arabidopsis, such as autonomous, gibberellin, vernalization and photoperiod pathways. In addition, brassinosteroid, stress-induced and floral suppression pathways were implicated as additional novel pathways. Notably, a difference in vernalization between Arabidopsis and poplar was revealed. Autonomous, gibberellin, vernalization, photoperiod, ethylene, brassinosteroid, stress-induced and floral suppression pathways integrated into a systematic gene network in floral development of poplar. Compared to Arabidopsis, brassinosteroid, stressinduced and floral suppression pathways are additional in poplar, and FLC is absent in vernalization pathway in poplar. Preliminary conclusions drawn here provide a basis for both identification of key genes and elucidation of molecular mechanisms involved in poplar floral development.

The purpose of this paper is to provide reference data related to the body weight, food & water consumptions, urinalysis, hematology and serum biochemistry parameters and absolute & relative organ weights obtained from control Sprague-Dawley rats, used in the 4-week and 13-week repeated-dose toxicity studies conducted in our laboratory between 2005 and 2008. The mean, standard deviation, minimum and maximum range values for hematology and serum biochemistry parameters, data of absolute & relative organ weights, and the difference between sexes and study duration of week 4 versus 13 week are presented. The studies were conducted according to “the standards of Toxicity Study for Medicinal Products” (2005) and The KFDA Notification No. 2000-63 ‘Good Laboratory Practice (GLP)’ (2000) issued by KFDA. These data could be used as reference material of Sprague-Dawley rats by conducting the studies to evaluate the toxicological profile of pre-clinical toxicity studies.

Background Postoperative cognitive dysfunction (POCD) is a neurodegenerative disorder with impairment of cognition. Sevoflurane anesthesia has been found to lead to CD and microRNAs (miRNAs) were reported to affect cognitive function. This study investigates the neuroprotective effect against sevoflurane anesthesia-induced CD. Methods HE staining was used to detect the pathological change of hippocampal neuron. Morris water maze test was used to analyze latency time, platform crossing and swimming speed. Quantitative real-time PCR (qRT-PCR) and western blotting were performed to examine the mRNA and protein expression of miR-410-3p, IL-6, TNF-α, IL-1β and C–X–C motif chemokine receptor 5 (CXCR5). Dual-luciferase reporter assay was used to detect the relationship between miR-410-3p and CXCR5. Results MiR-410-3p was downregulated in sevoflurane anesthesia-induced rats and cells and act as a suppressor in sevoflurane anesthesia-induced hippocampal neuron apoptosis and inflammation. Furthermore, miR-410-3p was identified to bind with CXCR5. Further analysis showed that CXCR5 expression was increased by sevoflurane treatment, whereas was repressed by miR-410-3p overexpression. Moreover, miR-410-3p could inhibit sevoflurane anesthesia-induced hippocampal neuron apoptosis by phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) pathway. Conclusion These data indicated that miR-410-3p exhibited its neuroprotective effect on sevoflurane anesthesia-induced CD by targeting CXCR5 via PI3K/Akt signaling pathway. Our study may potentially provide a new light on the pathogenesis and therapeutic method for sevoflurane anesthesia-induced CD.

<P><B>Abstract</B></P><P> A number of germ cell-specific transcription factors essential for ovarian formation and folliculogenesis have been identified and studied. However, the role of these factors during early embryonic development has been poorly explored. In the present study, we investigated the role of SEBOX, a maternal homeobox transcription factor, during early embryonic development in porcine parthenotes. mRNA for <I>SEBOX</I> is preferentially expressed in oocytes, and expression persists until embryonic genome activation (EGA). Knockdown of SEBOX by siRNA disrupted early embryonic development, but not oocyte maturation. Many maternal genes essential for early embryonic development were upregulated in SEBOX-depleted embryos. Moreover, some pluripotency-associated genes, including <I>SOX2</I> and <I>NANOG</I>, were upregulated when SEBOX was knocked down. Therefore, our data demonstrate that SEBOX is required for early embryonic development in pigs and appears to regulate the degradation of maternal transcripts and the expression of pluripotency genes.</P>
