IBB PAS scientists make important discoveries about plant viruses

New Phytologist, one of the most prestigious journals in plant science with over 120 years of tradition, has recently published an article entitled “The Rysto immune receptor recognizes a broadly conserved feature of potyviral coat proteins”. The authors of the article are colleagues from our Institute: Marta Grech-Baran, Anna Grupa-Urbańska, Małgorzata Lichocka, Jarosław Poznański and Jacek Hennig. The article describes molecular mechanism leading to the recognition of multiple viruses of the Potyviridae family by a cytoplasmic Rysto immune receptor. Potyviruses are the largest genus of RNA viruses, infecting both monocotyledonous and dicotyledonous plants, which are food sources. The results presented are an example of a perfect fusion of basic and applied sciences.

The results were achieved in collaboration between the Laboratory of Plant Pathogenesis IBB PAS with the Laboratory of Prof. Jonathan D. G. Jones at The Sainsbury Laboratory, Univ. of East Anglia, Norwich, UK.
