    On the regulation of populations of mammals, birds, fish, and insects (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-07-26
    Description: A key unresolved question in population ecology concerns the relationship between a population's size and its growth rate. We estimated this relationship for 1780 time series of mammals, birds, fish, and insects. We found that rates of population growth are high at low population densities but, contrary to previous predictions, decline rapidly with increasing population size and then flatten out, for all four taxa. This produces a strongly concave relationship between a population's growth rate and its size. These findings have fundamental implications for our understanding of animals' lives, suggesting in particular that many animals in these taxa will be found living at densities above the carrying capacity of their environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sibly, Richard M -- Barker, Daniel -- Denham, Michael C -- Hone, Jim -- Pagel, Mark -- New York, N.Y. -- Science. 2005 Jul 22;309(5734):607-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Animal and Microbial Sciences, University of Reading, Whiteknights, Reading RG6 6AJ, UK. r.m.sibly@reading.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16040705" target="_blank"〉PubMed〈/a〉

    Gene for von Recklinghausen neurofibromatosis is in the pericentromeric region of chromosome 17 (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-05-29
    Description: Linkage analysis of 15 Utah kindreds demonstrated that a gene responsible for von Recklinghausen neurofibromatosis (NF) is located near the centromere on chromosome 17. The families also gave no evidence for heterogeneity, indicating that a significant proportion of NF cases are due to mutations at a single locus. Further genetic analysis can now refine this localization and may lead to the eventual identification and cloning of the defective gene responsible for this disorder.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barker, D -- Wright, E -- Nguyen, K -- Cannon, L -- Fain, P -- Goldgar, D -- Bishop, D T -- Carey, J -- Baty, B -- Kivlin, J -- CA 28854/CA/NCI NIH HHS/ -- CA 36362/CA/NCI NIH HHS/ -- GM 29090/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 May 29;236(4805):1100-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3107130" target="_blank"〉PubMed〈/a〉

    Cystic fibrosis locus defined by a genetically linked polymorphic DNA marker (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-11-29
    Description: A polymorphic DNA marker has been found genetically linked, in a set of 39 human families, to an autosomal recessive gene that causes cystic fibrosis (CF), a disease affecting one in 2000 Caucasian children. The DNA marker (called D0CRI-917) is also linked to the PON locus, which by independent evidence is linked to the CF locus. The best estimates of the genetic distances are 5 centimorgans between the DNA marker and PON and 15 centimorgans between the DNA marker and the CF locus, meaning that the location of the disease gene has been narrowed to about 1 percent of the human genome (about 30 million base pairs). Although the data are consistent with the interpretation that a single locus causes cystic fibrosis, the possibility of genetic heterogeneity remains. The discovery of a linked DNA polymorphism is the first step in molecular analysis of the CF gene and its causative role in the disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsui, L C -- Buchwald, M -- Barker, D -- Braman, J C -- Knowlton, R -- Schumm, J W -- Eiberg, H -- Mohr, J -- Kennedy, D -- Plavsic, N -- New York, N.Y. -- Science. 1985 Nov 29;230(4729):1054-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2997931" target="_blank"〉PubMed〈/a〉

    Ancestral alliances: Plant mutualistic symbioses with fungi and bacteria (2017)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2017-05-26
    Description: Within the plant microbiota, mutualistic fungal and bacterial symbionts are striking examples of microorganisms playing crucial roles in nutrient acquisition. They have coevolved with their hosts since initial plant adaptation to land. Despite the evolutionary distances that separate mycorrhizal and nitrogen-fixing symbioses, these associations share a number of highly conserved features, including specific plant symbiotic signaling pathways, root colonization strategies that circumvent plant immune responses, functional host-microbe interface formation, and the central role of phytohormones in symbiosis-associated root developmental pathways. We highlight recent and emerging areas of investigation relating to these evolutionarily conserved mechanisms, with an emphasis on the more ancestral mycorrhizal associations, and consider to what extent this knowledge can contribute to an understanding of plant-microbiota associations as a whole.
