Rhizobium leguminosarum bv. trifolii SRDI943 (strain syn. V2-2) is an aerobic, motile, Gram-negative, non-spore-forming rod that was isolated from a root nodule of Trifolium michelianum Savi cv. Paradana that had been grown in soil collected from a mixed pasture in Victoria, Australia. This isolate was found to have a broad clover host range but was sub-optimal for nitrogen fixation with T. sub...

A total o f 28 strains o f several species o f Rhizobium were screened for the presence and regulation of the enzyme alkaline phosphatase. In contrast to all other species o f Rhizobium, the activity of this enzyme was absent in R. trifolii. D ifferent levels o f alkaline phosphatase were observed in various species o f Rhizobium. Both, species as well as strain specific differences were found ...

گیاهان یونجه و شبدر به دلیل ارزش غذایی زیاد در تعلیف اهمیت فراوانی دارند و دارای اثر مفیدی بر ساختار خاک هستند. نقش این گیاهان در تعلیف دام و در نتیجه تأمین نیاز انسان به فرآورده های دامی از اهمیت غیر قابل انکاری برخوردار است. با این وجود متأسفانه در کشور ما به تولید و مدیریت گیاهان علوفه ای در مقایسه با سایر محصولات زراعی کمتر توجه شده است. سفیدک پودری یونجه و شبدر یکی از بیماری های مهم در پار...

Although Polychronopolis and Lownsbery (1) found that Heterodera schachtii invaded the radicle, hypocotyl, and cotyledons of seedling sugarbeet, they observed no histological or cytological changes other than cellular death and disorganization. Ross (2) reported development of females and brown cysts accompanied by formation of giant cells and hypertrophy in leaves of white clover inoculated wi...

We resolved previous conflicting results concerning the presence of 3-hydroxybutyryl substituents on the extracellular acidic polysaccharide from Rhizobium trifolii 0403. These substituents were indeed present in the polysaccharide and in the oligosaccharide fragments obtained by hydrogen fluoride solvolysis of the extracellular and capsular polysaccharides of the bacteria grown on plates. The ...
