Grazing effect on vegetation cover and soil factors in natural environments is inevitable. The present study was conducted to investigate the effect of grazing on soil factors and distribution of plant species in grazed and non-grazed areas in rangelands of western parts of Hoz-e-Soltan Lake, Qom. Systematic-randomized sampling method was used alongside of 4 transects. Adjacent to the transects...
Suaeda salsa is a leaf-succulent euhalophytic plant capable of surviving under seawater salinity. Here, we report the isolation and functional analysis of a novel Suaeda gene (designated as SsTypA1) encoding a member of the TypA/BipA GTPase gene family. The steady-state transcript level of SsTypA1 in S. salsa was up-regulated in response to various external stressors. Expression of SsTypA1 was ...
خلاصه فارسی به علت ارتباط گونه های فعال اکسیژن با پیری، سرطان و بسیاری از بیماری های دیگر علاقه به بررسی آنتی اکسیدان ها رشد چشمگیری داشته است. با توجه به اینکه آنتی اکسیدان های سنتتیک مانند bht می توانند کارسینوژن و همچنین هپاتوتوکسیک باشند، وجود خاصیت آنتی اکسیدانی در مواد طبیعی مانند گیاهان از اهمیت خاصی برخوردار است. suaeda vermiculata forssk یکی از گیاهان بومی ایران بوده و متعلق به تیره ...
Parasitism in flowering plants has evolved at least 11 times [1]. Only one family, Orobanchaceae, comprises all major nutritional types of parasites: facultative, hemiparasitic (partially photosynthetic), and holoparasitic (nonphotosynthetic) [2]. Additionally, the family includes Lindenbergia, a nonparasitic genus sister to all parasitic Orobanchaceae [3-6]. Parasitic Orobanchaceae include spe...
OBJECTIVE To investigate the antioxidant, antimicrobial, antiplasmodial, acute toxicity and haemolytic activities of methanolic extracts of three plants. Phytochemical analysis to determine the phenolic contents was also carried out. METHODS The 2,2-diphenyl-1-picryl-hydrazyl (DPPH) free radical scavenging, NCCLS broth microdilution and Plasmodium Lactate Dehydrogenase (pLDH) assays were used...
6 The ability to develop invasive haustoria is the key feature of parasitic angiosperms. 7 The haustorium attaches the parasite to the host, penetrates the host while keeping 8 its own tissues intact, develops a vascular continuity between the host and parasite 9 and ultimately provides the conduit through which host and parasite materials flow. 10 The ability to make haustoria distinguishes pa...
Two new cyclic lipopeptides maribasins A (1) and B (2) were isolated from the fermentation broth of the marine microorganism Bacillus marinus B-9987 isolated from Suaeda salsa in Bohai coastline of P. R. China. Both structures were established to be cyclo (D-Pro-L-Gln-L-Asn-L-Ser-D-Asn¹-D-Tyr-D-Asn²-D-β-aminoisopentadecanoic acid) (1) and cyclo (D-Pro-L-Gln-L-Asn-L-Ser-D-Asn¹-D-Tyr-D-Asn²-D-β-a...
این مطالعه جهت امکانسنجی استفاده از چهارگونه هالوفیت یکساله به نامهای،Kochia scoparia ،Atriplex arcuata، Suaeda dimorphestegia و Salsola crassa بهعنوان گیاه علوفهای در شرایط آبیاری با آب شور در طی سالهای 1382، 1383 و 1384 انجام شد. آزمایشها در مزرعه در قالب طرح کرتهای خرد شده با سه تکرار انجام شد که در آن سه تیمار شوری، آب و آبیاری ( 5/1، 5/9 و 0/26 دسیزیمنس بر متر) بهعنوان کرتهای اصلی و...
