    Notes: In this work, we examine whether the “nexin” linkages of the flagellum can extend in length to accommodate interdoublet sliding. Flagellar bends of large angle were induced in bull spermatozoa by hypotonic treatment. It is argued that this produces large interdoublet displacements that are, nevertheless, still within physiological limits. Such flagella were examined by the rapid-freeze, deep-etch techique and the nexin linkages identified by their position in relation to the inner dynein arms and by their straplike, bipartite, morphology. They were found to bridge perpendicularly (or occasionally at an angle) between the A- and B-tubules of adjacent doublets. The nexin linkages were no more than ∼20 nm in length, even in regions in which ∼200 nm of sliding could be inferred. Variable registration between adjacent nexin rows gave some further support to the assumption that sliding had indeed taken place. From this, it is concluded that elastic deformation of the links, such as would accommodate interdoublet sliding, does not occur; some form of displacement must occur between nexin and the adjacent B-tubule. © 1993 Wiley-Liss, Inc.

    Description: Accelerated gene evolution is a hallmark of pathogen adaptation following a host jump. Here, we describe the biochemical basis of adaptation and specialization of a plant pathogen effector after its colonization of a new host. Orthologous protease inhibitor effectors from the Irish potato famine pathogen, Phytophthora infestans, and its sister species, Phytophthora mirabilis, which is responsible for infection of Mirabilis jalapa, are adapted to protease targets unique to their respective host plants. Amino acid polymorphisms in both the inhibitors and their target proteases underpin this biochemical specialization. Our results link effector specialization to diversification and speciation of this plant pathogen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dong, Suomeng -- Stam, Remco -- Cano, Liliana M -- Song, Jing -- Sklenar, Jan -- Yoshida, Kentaro -- Bozkurt, Tolga O -- Oliva, Ricardo -- Liu, Zhenyu -- Tian, Miaoying -- Win, Joe -- Banfield, Mark J -- Jones, Alexandra M E -- van der Hoorn, Renier A L -- Kamoun, Sophien -- Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Jan 31;343(6170):552-5. doi: 10.1126/science.1246300.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Sainsbury Laboratory, Norwich Research Park, Norwich NR4 7UH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="" target="_blank"〉PubMed〈/a〉
