Biorecognition of HPMA copolymer-adriamycin conjugates by lymphocytes mediated by synthetic receptor binding epitopes

Autor: V, Omelyanenko, P, Kopecková, R K, Prakash, C D, Ebert, J, Kopecek

Publikováno v: Pharmaceutical research. 16(7)

The EDPGFFNVE nonapeptide (NP) was recognized as the CD21 (CR2) binding epitope of the Epstein-Barr virus (EBV) gp350/ 220 envelope glycoprotein which mediates the virus attachment to human B lymphocytes (Nemerow et al., Cell 56:369-377, 1989). Here

Creation of novel nitrogen-fixing actinomycetes by protoplast fusion of Frankia with streptomyces

Autor: R. K. Prakash, Brian Cummings

Publikováno v: Plant Molecular Biology. 10:281-289

Protoplast fusion was used for the creation of a novel actinomycete capable of fixing atmospheric nitrogen. Protoplasts of Streptomyces griseofuscus, a fast-growing actinomycete, and Frankia, a slow-growing actinomycete which fixes atmospheric nitrog

Conservation of IS66 homologue of octopine Ti plasmid DNA in Rhizobium fredii plasmid DNA

Autor: Neela Ramakrishnan, R. K. Prakash, Alan G. Atherly

Publikováno v: Plant Molecular Biology. 7:177-188

DNA sequences homologous to the T-DNA region of the octopine Ti plasmid from Agrobacterium tumefaciens are found in various fast-growing Rhizobium fredii strains. The largest fragment (BamHI fragment 2) at the right-boundary region of the 'core' T-DN

Relationship between Nif plasmids of fast-growing Rhizobium species and Ti plasmids of Agrobacterium tumefaciens

Autor: R K Prakash, R A Schilperoort

Publikováno v: Journal of Bacteriology. 149:1129-1134

By use of the Southern blot hybridization technique the extent of DNA homology was determined between the Nif plasmid of a number of fast-growing Rhizobium species and Ti plasmids of the octopine (pTiAch5) and nopaline (pTiC58) type. DNA sequences co

Evidence for nitrogen fixation (nif) genes on indigenous Rhizobium plasmids

Autor: Marco Nuti, Frank Cannon, R. A. Schilperoort, A. A. Lepidi, R. K. Prakash

Publikováno v: Nature. 282:533-535

The distinguishing characteristic of bacteria that belong to the genus Rhizobium is their ability to induce nodules and fix nitrogen in the roots of leguminous plants—hence their importance in agriculture. The demonstration of nitrogen-fixation by

Reiteration of genes involved in symbiotic nitrogen fixation by fast-growing Rhizobium japonicum

Autor: R. K. Prakash, A G Atherly

Publikováno v: Journal of Bacteriology. 160:785-787

By using cloned Rhizobium meliloti nodulation (nod) genes and nitrogen fixation (nif) genes, we found that the genes for both nodulation and nitrogen fixation were on a plasmid present in fast-growing Rhizobium japonicum strains. Two EcoRI restrictio

The Plasmids of Rhizobium and Symbiotic Nitrogen Fixation

Autor: R. K. Prakash, R.A. Schilperoort, P.J.J. Hooykaas, A. A. Lepidi, M.P. Nuti

Publisher Summary This chapter discusses the plasmids of Rhizobium and symbiotic nitrogen fixation. The interaction between members of the genus Rhizobium and leguminous plants is specific. Legumes belonging to a given cross-inoculation group can be

Molecular cloning and expression of Rhizobium fredii USDA 193 nodulation genes: extension of host range for nodulation

Autor: N Ramakrishnan, N. M. Duteau, R. K. Prakash, S. Shantharam, Alan G. Atherly

Publikováno v: Journal of bacteriology. 168(3)

DNA hybridization with the cloned nodulation region of Rhizobium meliloti as a probe revealed DNA homology with four HindIII fragments, 12.5, 6.8, 5.2, and 0.3 kilobases (kb) in size, of the symbiotic plasmid pRjaUSDA193. Both hybridization and compl
