  • Recently, a Cucumber mosaic virus (CMV) strain, named as CMV-209, was isolated from Glycine soja. In this study, symptom expression of CMV-209 was analyzed in detail in Nicotiana benthamiana by comparing with that of CMV-Fny, which is a representative strain of CMV. Using infectious cDNA clones of CMV strains 209 and Fny, symptom expression of various pseudorecombinants between these two strains were examined in the early and late infection stages. In the early infection stage, the pseudorecombinants containing Fny-RNA2 induced stunting and leaf distortion on the newly emerged leaves whereas the pseudorecombinants containing 209-RNA2 caused no obvious symptoms. In the late infection stage, the pseudorecombinants containing 209-RNA1 and Fny-RNA2 induced severe leaf distortion and stunting, while CMV-209 induced mild symptom and CMV-Fny caused typical mosaic, general stunting, and leaf distortion symptoms, indicating that RNA 2 encodes a symptom determinant(s) of CMV, which is capable of enhancing symptoms. Furthermore, our results support the possibility that natural recombination between compatible viruses can result in emergence of novel viruses causing severe damages in crop fields.

  • Cucumber mosaic cucumovirus (CMV) is an isometric plant virus with functionally divided genomic RNAs and a broad host range. RNA 1 and RNA 2 each encode one protein, both of which are essential for replication. RNA 3 encodes the viral coat protein and an additional protein thought to be involved in potentiating the cell-to-cell movement of the virus. Functions of the RNAs have been confirmed using a pseudorecombinant virus constructed with infectious cDNA-derived transcripts of the RNAs. Generally, CMV produces different symptoms in various host plants depending on the virus strains. In this mini-review, we describe the potential role of the genes associated with symptom expression of CMV RNAs.

  • Beet curly top virus is the DNA virus that is providing useful for basic studies of the infection of Arabidopsis thaliana with viral host and provides a system for studying both resistance and the molecular basis of symptom development. An importnat aspect of symptom development observed in BCTV-infected A. thaliana (ecotype Sei-O) was the induction of cell division on phloem and surrounding cortex cells. Analysis of the expression of GUS reporter gene activity in transgenic plants containing constructs with promoter of the auxin-inducible saur gene showed that saur promoter activity was induced concomitantly in symptomatic tissues at the inflorescence shoot tips of the transgenic lines. The auxin sensitivity tests showed that hypersusceptible ecotype, Sei-O produced more amounts of callus than susceptible ecotype, Col-O. These studies indicated that changes in auxin concentration were involved in the induction of cell division in BCTV-infected plants and clearly demonstrated that there was a strong correlation between auxin-induced gene expression and the activation of cell division.

  • Objective : Osim((惡心) stands for nausea which usually precede vomiting(嘔吐). Although it is very common symptom, we can't find the word Osim in some ancient classics. So we tried to find when it had appeared, and what had been its substitute in former medical classics. Material and Methods : The digitalized text in Zhonghuayidian(中華醫典) was used for text search. The text search was performed chronologically. Results : We found that there had been yokto(欲吐), yokgu(欲嘔), geongu(乾嘔), beon(煩), beonsim (煩心), simbeon(心煩), min(悶), ongi(溫氣) as the precedent expression of osim(惡心), which had appeared in Jebyungwonhuron(諸病源候論, 610) for the first time. Conclusion : Until Tang dynasty, there had been kinds of alternative expressions correspond to osim(nausea).

  • Objective : The present study aims to investigate differences in anger-related features in patients with somatic symptom disorder (SSD) compared to healthy controls, and to examine whether anger trait and anger regulation strategy are associated with clinical characteristics in patients with SSD. In addition, we examined the relationship between childhood adversity and SSD. Methods : 26 patients with SSD and 28 healthy controls were included. Anger-related features were assessed with State-Trait Anger Expression Inventory (STAXI). Clinical somatic symptoms were assessed using the somatization subscale of the Symptom Checklist-90-Revised and the Somatosensory Amplification Scale. Childhood adversity was assessed by the Childhood Traumatic Events Scale. Multivariate analysis of covariance was performed. Results : Disease status of SSD had a significant overall effect on anger-related features (Wilks λ=0.725, F(5, 44)=3.332, p=0.012). Patients with SSD showed a significantly high Trait-Anger (p=0.017) and they had a high score in both Anger-Out (p=0.013) and Anger-In (p=0.001) of anger expression styles. In particular, a directed inward style of anger expression was significantly associated with somatization symptom severity (p=0.003). Regarding childhood adversity, more childhood extreme illness was experienced by the SSD group than the control group (p=0.012). Within the SSD group, childhood extreme illness was associated with higher Trait-Anger (p=0.027) and Anger-Out (p=0.001). Conclusion : The present findings suggest that trait anger, anger expression styles, and childhood adversity of extreme illness may be involved in SSD. Further studies are needed to explore the role of anger-related features and its relationship with childhood adversity in the pathophysiology of SSD.

  • Purpose: The purpose of this study was to identify type of anger expression and mental health in middle aged women. Methods: From August to October 2005, survey data were collected by using the State Trait Anger Expression Inventory and Symptom Check List-90-Revision (SCL). Participants (1,442) were classified into four types of anger expression by K-mean cluster analysis. For collecting interview data for content analysis, 18 participants (4-5 participants from each type of anger expression) were recruited. The interview data were collected between March and September 2006. Results: The average score of the state anger of middle-aged women was 11.95, and that of the trait anger was 18.75. The average anger expression scores were 12.72 for Anger-In, 13.45 for Anger-Out, and 18.51 for Anger-Control. The average SCL scores were 45.03 for somatization, 42.23 for obsessive-compulsiveness, 42.44 for interpersonal sensitivity, 42.45 for depression, 42.40 for anxiety, 42.62 for hostility, 44.44 for phobic anxiety, 43.65 for paranoid ideation, and 43.08 for psychoticism. The anger expression types identified in this study were 1) anger-out in secret, 2) anger-control with a patience, 3) anger-out with suppression, and 4) low anger expression type. The psychosomatic symptom scores were the highest in type III (anger-out with suppression), and the lowest in type IV (low anger expression type). Conclusion: This study can be helpful in assisting middle aged women to control their anger effectively and may contribute to the improvement of their mental health.

  • Arabidopsis infected with beet curly top virus (BCTV) has the systemic symptoms like stunting of Plant growth, curling of leaves and shoot tips, and callus induction. The regulation of sucrose metabolism by BCTV infection is essential for obtaining the energy source in the process of virus replication and symptom development. Sucrose metabolism-associated gene expression and biochemical enzyme activity were analyzed with the rossette leaves and inflorescencestems of BCTV infected Arabidopsis by the time course of 1, 7, 14, 21 day postinoculation. The expression of invertase and sucrose synthase genes ( encoding sucrose-cleaving enzymes )was increased and reversely the level of Atkin10a ( sucrose non-fermenting gene ) was decreased, resulting by semi-quantitative reverse transcription polymerase chain reaction. The biochemical analysis of invertase and sucrose synthase activity was performed. The activity of neutral invertase in the inflorescence stems was elevated remarkably. The photosynthetic response in the source of sucrose metabolism was consistent with the down-regulation of ribulose 1,5 bisphosphate carboxylase gene, and lower activity than mock-inoculated plants. The levels of genes pertaining to the cell cycle, hormone, and biotic stress-related pathway showed an increase or a decrease dependent on viral symptoms. Therefore, sucrose sensing by BCTV infection can regulate the expression of sucrose metabolism-related key enzymes such as invertase and Atkin10a, and these gene products might influence to symptom development.

  • The factors for symptom development caused by Beat curly top virus(BCTV) have been analyzed by using a molecular genetic approach based on expressing BCTV encoded proteins in transgenic plants. BCTV open reading frame (ORF) L4 expression in transgenic Arabidopsis resulted in abnormal plant development and the production of callus inflorescence stems and bumpy trichomes, confiming that this gene alone is a primary symptom determinant. The L4 gene expression by northern hybridization in transgenic plants and a range of phenotypes were analyzed.
