  • The biocontrol approach using beneficial microorganisms to control crop diseases is becoming an essential alternative to chemical fungicides. Therefore, new and efficient biocontrol agents (BCA) are needed. In this study, a rhizospheric actinomycete isolate showed unique and promising antagonistic activity against three of the most common phytopathogenic fungi, Fusarium oxysporum MH105, Rhizoctonia solani To18, and Alternaria brassicicola CBS107. Identification of the antagonistic strain, which was performed according to spore morphology and cell wall chemotype, suggested that it belongs to the Nocardiopsaceae. Furthermore, cultural, physiological, and biochemical characteristics, together with phylogenetic analysis of the 16S rRNA gene (OP869859.1), indicated the identity of this strain to Nocardiopsis alba. The cell-free filtrate (CFF) of the strain was evaluated for its antifungal potency, and the resultant inhibition zone diameters ranged from 17.0 ± 0.92 to 19.5 ± 0.28 mm for the tested fungal species. Additionally, the CFF was evaluated in vitro to control Fusarium wilt disease in Vicia faba using the spraying method under greenhouse conditions, and the results showed marked differences in virulence between the control and treatment plants, indicating the biocontrol efficacy of this actinomycete. A promising plant-growth promoting (PGP) ability in seed germination and seedling growth of V. faba was also recorded in vitro for the CFF, which displayed PGP traits of phosphate solubilization (48 mg/100 ml) as well as production of indole acetic acid (34 ㎍/ml) and ammonia (20 ㎍/ml). This study provided scientific validation that the new rhizobacterium Nocardiopsis alba strain BH35 could be further utilized in bioformulation and possesses biocontrol and plant growth-promoting capabilities.

  • This paper is intended to study what kinds of the vegetables are mentioned in the Bible and how they were used in those days. While one hundred and twenty-eight different plants are mentioned in the Bible, there are today 2,384 plant species in modem Israel, most of which have been introduced in recent centuries. These plants obviously did not exist there in biblical times and were only recently introduced from Australia and South America, respectively. This article will study only the vegetables mentioned in the Bible and known to have existed in the old and new testament times. Since the first book devoted exclusively to biblical botany was that of Levinus Lemmens in 1566, the modem systematic study of biblical plants, began with F. Hasselquist, a student of Linnaeus, the founder of modem botany. In 1928, Immanuel Loew approached the subject differently, reviewing all known data pertaining to biblical plants. His work not only discussed biblical plants, but also plants in later Jewish literature, particularly the Talmud. The British scholar G. E. Post provided a broad field study of modem plants in Palestine, Syria, Lebanon, and Jordan. More recent major treatments of the subject include those of A. and H. Moldenke (1952), M. Zohary (1982), N. Hareuveni (1984), and Y. J. Choi(1996). Today, articles on specific biblical plants listed in the Bible can be found in any number of encyclopedias. This study attempts to provide a synthesis of the work of a number of scholars who studied the vegetables and plants mentioned in the Bible. As a preliminary study on the culture of food in the biblical period, this study has focused on the identity and features of the vegetables of the Bible. In only a limited number of instances, because of the paucity of the informations and the broad and generic descriptions of the plants, we can't be certain about the identification of the vegetables named in the Bible. In many instances the traditions established by the Greek, Aramaic, and English translations are helpful, although sometimes they are misleading. This paper subdivides the vegetables into broad areas, the general vegetables and the flavoring herbs. Vegetables formed very important part of the diet in the biblical times. Two main types were used: those whose nutritious seeds could be easily stored and those which were eaten freshly gathered from gardens. Pulse seeds provided a useful source of vegetable protein, while fresh green vegetables were vitamin rich. Pulses could be eaten boiled, or their dried seeds could be ground up into flour and then made into nutritious soups. Fresh vegetables were eaten either raw or lightly cooked, usually by boiling in water. The general vegetables in the Bible are herbs(garden rocket), cucumber(snake cucumber), watermelon, leeks, chicory, and onions. Also the flavoring herbs in the Bible are rue, dill, cummin, black cummin, frankincense, cinnamon, cassia, myrrh, black mustard, coriander, mint, saffron, ginger grass, syrian hyssop, aloes(eagle wood), manna which have the flavor, aroma, and medical values.

  • A new macroscopic riverine red algal species, Lemanea manipurensis sp. nov. (Batrachospermales) is described from Manipur in northeast India. It has a sparsely branched, pseudoparenchymatous thallus with a single, central axial filament that lacks cortical filaments. Spermatangia occur generally in isolated, low and indistinct patches or form an almost continuous ring around the axis. Carposporophytes project into the hollow thallus cavity without an ostiole. The most striking morphological feature is the carposporophyte with very short gonimoblast filaments having cylindrical, narrow and sparsely branched sterile filaments, the terminal cell of each branch with a single, large, elongate carpospore. The widely distributed L. fluviatilis has spherical carpospores in long branched chains. Phylogenetic analysis of rbcL sequence data and comparison with other Batrachospermales clearly show that our specimens do not align with other species of Lemanea and Paralemanea investigated thus far. Five specific names attributed in previous literature (1973-2014) to Lemanea from Manipur, L. australis, L. catenata, L. fluviatilis, L. mamillosa, and L. torulosa are rejected until critical anatomical and molecular evidence is available for specimens from the Manipur river systems. Taxa referable to Paralemanea were not confirmed for India in this study. In view of the high demand for food and medical uses of L. manipurensis in northeast India, conservation measures are needed for its long term survival. The present paper constitutes the first combined morphological / molecular study on a freshwater red alga from India.

  • After Vanherweghem J-L reported the rapidly progressive interstitial renal fibrosis that developed in patients taking the slimming preparation compounded with chinese Herb in Belgium 1993. Chinese Herb Nephropathy(CHN) has become known as a new renal disease, CHN is described as the decrease of urinary renal enzyme, neutral endopeptidase(NEP). N-acetyl-${\beta}$-Dglucosaminidase(NAG). increase of urinary low molecular protein, ${\alpha}$1-microglobulin, ${\beta}$2-microglobulin. clara cell protein(CC16), retinol-binding protein(RBP) in clinical findings, and the proximal tubular atrophy, interstitial fibrosis. urothelial atrophy. glomerular sclerosis in histology, Because CHN was caused by Chinese herb contained in slimming preparation, western medical doctors have thought that all Herb medicine might have caused renal disease and prohibit the taking of any Herb medicine, However. CHN was actually caused by the aristolochic acid contained in some Herb medicines. Aristolochia manshuriensis, Aristolochia fang chi, which is the substitutions of Akebia quinata, Stephania tetrandra has being used in clinical. Aristolochia manshuriensis. Aristolochia fang chi were different with Akebia quinata. Stephania tetrandra in botany, and it have not been classified with medicines in Oriental medicine, That is, the aristolochic acid, not Herb medicines. causes CHN, So, Chinese Herb Nephropathy should be changed to Aristolochic acid Nephropathy.

  • Crude extracts or phytochemicals obtained from some plants have potential anti-cancer properties. Teucrium persicum is an Iranian endemic plant belonging to the Lamiaceae family which has traditionally been used to relieve abdominal pains. However, the anti-cancer properties of this species of the Teucrium genus have not been investigated previously. In this study, we have used a highly invasive prostate cancer cell line, PC-3, which is an appropriate cell system to study anti-tumor properties of plants. A methanolic extract obtained from T persicum potently inhibited viability of PC-3 cells. The viability of SW480 colon and T47D breast cancer cells was also significantly decreased in the presence of the T persicum extract. Flow cytometry suggested that the reduction of cell viability was due to induction of apoptosis. In addition, the results of wound healing and gelatin zymography experiments supported anti-cell invasion activity of T persicum. Interestingly, sublethal concentrations of T persicum extract induced an epithelial-like morphology in a subpopulation of cells with an increase in E-Cadherin and ${\beta}$-Catenin protein levels at the cell membrane. These results strongly suggest that T persicum is a plant with very potent anti-tumor activity.
