A variety of stress situations may affect the activity and survival of plant-beneficial pseudomonads added to soil to control root diseases. This study focused on the roles of the sigma factor AlgU (synonyms, AlgT, RpoE, and sigma(22)) and the anti-sigma factor MucA in stress adaptation of the biocontrol agent Pseudomonas fluorescens CHA0. The algU-mucA-mucB gene cluster of strain CHA0 was simi...
The translocator protein (TSPO), previously designated as peripheral-type benzodiazepine receptor, is a protein mainly located in the outer mitochondrial membrane of eukaryotic cells. TSPO is implicated in major physiological functions and functionally associated with other proteins such as the voltage-dependent anionic channel, also designated as mitochondrial porin. Surprisingly, a TSPO-relat...
Cocoa pod anthracnose is an important disease of cocoa and can reduce yields. Many attempts have been made to control rot on pods but not successful yet. This study aimed examine the potency secondary metabolite crude extracts produced by Trichoderma asperellum Pseudomonas fluorescens solely or in combination controlling field at Silo Bonto Village, Asahan Regency, North Sumatera Province. The ...
مقدمه: سودوموناسهای فلورسنت سیدروفورهای متعددی را تولید میکنند که مهمترین آنها سیدروفور نوع پایووردین است. تولید سیدروفور در این باکتریها باعث افزایش فراهمی آهن موردنیاز باکتری و گیاهان میشود و همچنین اهمیت ویژهای در کنترل بیماریهای گیاهی دارد. مواد و روشها: بهمنظور مقایسۀ روشهای اندازهگیری تولید سیدروفور، میزان تولید سیدروفور 21 سویۀ سودوموناس بومی ایران بههمراه دو سویۀ مرجع خارجی...
Brazil has 180 Mha of pastures, 86 occupied with Urochloa spp. (syn. Brachiaria), and 70% in some level degradation. Inoculation plant-growth-promoting bacteria (PGPR) may represent an economic environmental feasible strategy to improve pasture production. Two greenhouse seven field trials were performed verify the effects seed inoculation at sowing or leaf-spray established pastures elite stra...
This study was carried out at the forest nursery of Department of Forestry, Faculty of Agriculture and Regional Research Station, Wadura SKUAST-K, Sopore, Kashmir during 2006 and 2007 to examine the role of live biofertilizers in litter decomposition and nutrient release in Salix fragilis under natural Salix stands. The experiment was laid in completely randomised design with three replications...
In the previous half-century, natural rock phosphates (PN) have been a valuable alternative for phosphorus (P) fertilizer sustainable agriculture; furthermore, phosphogypsum (PG) has widely used as soil amendment since it improves some properties, increases crop yields, and represents an environmental concern that can make good economic profit; this research aimed to study effects of microbial ...
A study to attain healthy tomato (Lycopersicon esculentum Mill) seedlings through environment-friendly natural biological products took place from January March 2022. Determining the effects of inoculum prepared five plant growth-promoting rhizobacteria (PGPR) isolates, i.e., Pseudomonas fluorescens, putida, Lysinibacillus fusiformis, Enterobacter cloacae, and Kineococcus radiotolerans on produ...
A cosmid clone isolated from a genomic library of Pseudomonas syringae pv. syringae 61 restored to all Tn5 mutants of this strain studied the ability to elicit the hypersensitive response (HR) in tobacco. Cosmid pHIR11 also enabled Escherichia coli TB1 to elicit an HR-like reaction when high levels of inoculum (10(9) cells per ml) were infiltrated into tobacco leaves. The cosmid, which contains...
To study the effect of chemical and biological fertilizers on growth and essential oil content of lavender (Lavandula angustifolia Mill.), the present work was conducted in 2012-2013 at the experimental field of Alborz Research Station of the Research Institute of Forests and Rangelands, Karaj, Iran. The experiment was conducted in factorial in the form of a randomized complete block design wit...
