چکیده: قارچ های میکوریز آربوسکولار (am) از دیرباز به عنوان همزیست ریشه گیاهان در بهبود رشد آنها در شرایط فقر غذایی و تنش های محیطی، موثر شناخته شده است. علی رغم فواید بیشمار این همزیستی، تکثیر انبوه این قارچ ها به دلیل ماهیت اجباری این همزیستی، تاکنون در محیط های مصنوعی امکان پذیر نبوده و صرفاً در حضور ریشه زنده تکثیر می یابند. شواهدی وجود دارد که حضور برخی میکروارگانیسم ها از جمله اکتینومیست ه...
قارچهای میکوریز آربوسکولار (am) از دیرباز بهعنوان همزیست ریشه اکثر گیاهان در بهبود رشد آنها در شرایط فقر غذایی و تنشهای محیطی مؤثر شناخته شده است. شواهدی وجود دارد که حضور برخی میکروارگانیسمها از جمله اکتینومیستها یا برخی متابولیتهای حاصل از آنها با افزایش سرعت و مقدار تندش اسپور قارچهای am و تولید هیفهای بیشتر، تکثیر انبوه این قارچها را فراهم کرده و پتانسیل زادمایه آنها را افزایش داده...
A series of angucyclinone antibiotics have been isolated from marine Streptomyces sp. strain W007 and identified. Here, a draft genome sequence of Streptomyces sp. W007 is presented. The genome contains an intact biosynthetic gene cluster for angucyclinone antibiotics, which provides insight into the combinatorial biosynthesis of angucyclinone antibiotics produced by marine streptomycetes.
Three plant-pathogenic isolates of Streptomyces spp., isolated from potatoes with common scab disease lesions in Korea, are described as novel species. Morphological and physiological properties of these isolates were distinct from those of previously described Streptomyces species. Strain S63(T) has yellow-white, smooth, cylindrical spores that are borne in monoverticillus flexuous spore-chain...
We have previously isolated a new actinomycete strain from Tunisian soil called Streptomyces sp. US24, and have shown that it produces two bioactive molecules including a Cyclo (L-Phe, L-Pro) diketopiperazine (DKP). To identify the structural genes responsible for the synthesis of this DKP derivative, a PCR amplification (696 bp) was carried out using the Streptomyces sp. US24 genomic DNA as te...
Streptomyces sp. TP-A0867 (=NBRC 109436) produces structurally complex polyketides designated alchivemycins A and B. Here, we report the draft genome sequence of this strain together with features of the organism and assembly, annotation, and analysis of the genome sequence. The 9.9 Mb genome of Streptomyces sp. TP-A0867 encodes 8,385 putative ORFs, of which 7,232 were assigned with COG categor...
Streptomyces sp. H-KF8 is a fjord-derived marine actinobacterium capable of producing antimicrobial activity. Streptomyces sp. H-KF8 was isolated from sediments of the Comau fjord, located in the northern Chilean Patagonia. Here, we report the 7.7-Mb genome assembly, which represents the first genome of a Chilean marine actinobacterium.
Streptomyces sp. fd2-tb can produce streptothricin class antibiotics with broad antimicrobial spectra. To better understand the mechanism of streptothricin biosynthesis and to assess the capacity of this strain in secondary metabolism, we report the draft genome sequence of Streptomyces sp. strain fd2-tb.
We report the draft genome sequence of Streptomyces sp. M1013, a strain isolated from the Medicago arborea rhizosphere in Izmir, Turkey. An average nucleotide identity (ANI) analysis reveals that this strain belongs to the same species as Streptomyces canus ATCC12647 and is closely related to Streptomyces ambofaciens and Streptomyces coelicolor.
