Due to recent interest of the consumers on safe farm products and the government's political support for eco-friendly agriculture, organic fruit production has been growing continuously. This research was conducted in order to study the effect of cover plants on soil microbial community on cover plants and establish an organic fruit cultivation method through choosing optimal cover plant. As a result of investigating soil microbial population density, the bacterial density in soil showed an increasing trend in June compared to April, and there was a decreasing trend in bacterial density of the soil in August compared to June. The density of actinomycetes in soil increased around 1.6 times in June compared to April when the soil was covered with hairy vetch. The increase of filamentous fungus in crimson clover group was 6.1 times higher in June compared to April and in hairy vetch group, the increase was 4.9 times higher in June compared to April. As a result of analyzing DNA extracted from the soil categorized by different types of cover plants using DGGE method, soil collected from April had higher number of bands detected from different locations according to different types of cover plants. Diversity of the bands from the soil collected from August showed higher range of reduction. As a result of analyzing soil microbial community by different period and the types of cover plants using Pyrosequencing method, microbes were detected in the order of Proteobacteria, Acidobacteria, Actinobacteria, Bacteroidetes, Chloroflexi, and Firmicutes. Distribution rate of Firmicutes increased in the soil collected in August compared to June and this was shown in all types of cover plants by twice the amount.

Introduction: Mastalgia is the most common benign breast disorder during the fertility period of women. So far a wide range of natural or complementary medicines is used to cure mastalgia. Sanitary organizations need complete and suitable details to help women, for making the proper decision for alternative treatment based on the evidence. The aim of the present study is to introduce medicinal plant-based treatments about mastalgia and summarizes clinical trials about this disorder. Method: The articles were provided using mixture of keywords including cyclic pain, breast, treatment, therapeutics, therapy, clinical trial, herbal, drug, mastalgia and all the probable terms, in national and international databases SID, Iran Medex, Magiran, PubMed, Scopus, Medline, Science direct and Cochrane library, in both Persian and English languages. All cross-sectional and review articles about herbal treatment of mastalgia until 2018 November were studied. Results: Nineteen articles from all of the available articles (45 cases) and a sample size about of (1987 cases) were included in our study. The articles were clinical trials. The results revealed that mastalgia could be healed by Nigella sativa, Vitex agnus-castus, curcumin, Hypericum perforatum, Citrus sinensis, wheat germ, and Ginkgo biloba. Conclusion: Most of the evaluated medicinal plants possessing antioxidant compounds with anti-inflammatory and analgesic properties, exhibited healing effects in the treatment of mastalgia. Thus, medicinal plants can be considered in the treatment of mastalgia; however, further investigations are needed to obtain more details about their probable side effects.

This study was conducted to investigate how to enhance resistance to oxidative stress in petunia progeny obtained by a crossing between transgenic plants, MnSOD (SOD2) ($T_4$) and NDPK2 ($T_2$), to develop transgenic petunia much more resistant to environmental stress. At the treatment of MV 200 ${\mu}M$, the progeny was significantly less damaged than its parental plants (SOD2- or NDPK2-transgenic lines) as well as wild type plants, implying its resistance to oxidative stress was enhanced compare to that of SOD2- or NDPK2- transgenic plants. In an expression of 11 quantitative traits, the progeny remained similar to control plants, although it infrequently displayed slightly longer or wider than either parental or wild type plants. In the expression of 6 qualitative traits, there was no significant difference between parental or non-transgenic control plants.

Background: Ginseng has been used as a medicine and functional food since ancient times. It is a perennial crop, and its whose commercial valuse increases with growing period and is affected by the atmosphere and soil environment. Methods and Results: In a selected field, we measured air temperature under a shade structure and soil physicochemical properties, and determied plant and root growth as well as ginsenoside and total polyphenol content of one- to five-year-old ginsengs plants. Although air temperature above 30℃ was recored for more than 37 days, no marked growth inhibition of ginseng was detected. Among all soil physicochemical properties, except for pH, were within the allowable range the shortage increases with ginseng years. In five-year-old ginseng, the quantity is about 9.7% higher than the average weight by standard, indicating that is not affected by temperature when grown under a shade structure. Three-year-old ginseng contained the highest total ginsenoside and total polyphenol levels and exhibited the greatest DPPH radical scavenging activity. Conclusions: The total ginsenoside and protopanaxadiol/protopanaxatriol ratio were both low at five-year-old ginseng plants, which was attributed to rapid growth of the root system in five-year-oid plants. There were no significant differences in total polyphenol content and antioxidant activity between.

In March, 2013, twenty symptomatic freesia plants (10 plants of cultivar Shiny Lemon and 10 plants of cultivar Shiny Gold), with striking virus-like symptoms were collected in Cheongju, Korea. The plants showed chlorotic, coalescing, interveinal, whitish, necrotic, mosaic, mottling or dark brown-to-purple necrotic spots on leaves. Freesia crude sap was directly analyzed by transmission electron microscopy, which potyvirus particles as well as long virus-like particles were detected. Total RNA extracts were analyzed for the infection of Freesia sneak virus (FreSV) by reverse transcription (RT)-PCR with primers specific to FreSV coat protein (CP) gene based on the sequences of FreSV isolates (GenBank No. GU071089, FJ807730 and DQ885455), showing 9 of 20 plants were infected. All 1305bp RT-PCR products were cloned and sequenced. Comparisons of nucleotide and deduced amino acid sequences using BLAST and bioinformatics tools resulted in 99 to 100% sequence identity with FreSV isolates FOV, Virginia, and Italy, confirming FreSV in 9 symptomatic freesia plants. Of 9 determined cDNAs of FreSV isolates, sequences of 5 cDNA clones were identical (GenBank No. AB811437) and sequences of 4 cDNA clones were identical (GenBank No. AB811792). To our knowledge, this is the first report of FreSV from Freesia spp. in Korea.

Objectives : This study was conducted to evaluate the antioxidative and fibrinolytic activity of the water and ethanol extracts from medicinal plants. Methods : Five kinds of medicinal plants(Carthami Flos, Glycyrrhizae Radix, Schisandrae Fructus, Atractylodes Rhizoma, Shiitake mushiroom) were extracted with distilled water and 70% ethanol, and the extracts were tested for their antioxidative and fibrilytic activities. Results : The highest polyphenol contents of the water and ethanol extracts from medicinal plants were 812.52 mg and 685.44 mg per 100 g of Carthamus tinctorius and Schizandra chinensis, respectively. The electron donating abilities (EDA) of the water extracts from all medicinal plants except Lentinus edodes were about 90% at 1,000 ppm and ethanol extracts were higher than those of water extracts. The highest SOD-like activity and nitrite scavenging abilities (NSA) were both of water and ethanol extracts from Schizandra chinensis. Five kinds of medicinal plants had fibrinolytoc activity and the highest activities were water and ethanol extracts from Glycyrrhiza uralensis. Conclusion : These results suggest that the medicinal plants can be used as natural antioxidant to prevent oxidative damage in normal cells probably because of their antioxidative and fibrinolytic activities.

The transfer of Mn-Superoxide Dismutase (SOD2) gene, complex gene (SA) of CuZnSOD and ascorbate peroxidase (APX), and NDP kinase 2 (NDPK2) gene into Korean 4 cultivars (cvs. Millenium White, Glory Blue, Glory Red, and Glory Purple) and 15 purebred lines of petunia was conducted using Agrobaterium-mediated technique. Two (Wongyo A2-16 and A2-36) of 15 purebred lines and one (cv. Glory Red) of 4 cultivars were effective for the transfer of SOD2 gene. The putative transgenic plants survived on the 2nd selection medium were 124. From PCR analysis, 118 (derived from 4 cultivars and 2 purebred lines) of 124 plants were confirmed to contain marker (npt II ) gene, while 58 of 118 plants did not have target genes. There were no plants with both npt II and SA genes. Twenty seven of 28 SOD2 transgenic plants were re-confirmed as transformants by Sothern analysis. SOD2 and NDPK2 genes were expressed in the transgenic petunias as the ratio of 77.8 to 100.0 % and 23.5%, respectively. T1 seeds were obtained from 36 acclimated transgenic plants (SOD2 34 plus NDPK2) in a glasshouse by self-pollination.
