  author={Serge Kauffmann and Michel Legrand and Bernard Fritig},
  journal={Plant Molecular Biology},
The purification to homogeneity of pathogenesis-related (PR) proteins R and S from Nicotiana tabacum cv. Samsun NN leaves has been achieved by using a combination of conventional and high-performance chromatographic supports. The same procedure allowed the purification and the characterization of four other proteins which displayed some properties characteristic of tobacco PR proteins and were shown to accumulate in tobacco leaves in response to virus infection. They can be, therefore… CONTINUE READING
