Linking networks and plant roles : The impact of changing a plant role
- 2010

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Many manufacturing firms are expanding their global footprint to explore new opportunities for efficient and effective production. The strategic perspective on international manufacturing networks involves both the network level and the plant level. A key aspect is the relationship between the network and the role of plants. In this research, we investigate the relationship between the network and plant perspectives in international manufacturing networks. We use a single in-depth case study that includes five plants in two product networks over a period of five years. We analyze how changing the role of one plant affects the network as well as the roles of the other plants in the network. Thus, decisions on plant roles are, to a very high degree, network decisions and not decisions for individual plants. Based on the insights from the case study we also develop a framework for mapping manufacturing networks, including market coverage, plant location and site competence.

The strategic perspective on international manufacturing networks involves both the network level and the plant level. A key aspect is the relationship between the network and the role of plants. In this research, we investigate the relationship between the network and plant perspectives in international manufacturing networks. We use an embedded case study that includes five plants in two product networks over a period of three years. We analyse how changing the role of one plant affects the network as well as the roles of the other plants in the networks. We find that decisions on plant roles are, to a very high degree, network decisions and not decisions for individual plants.

- Aphids are important agricultural pests and also biological models for studies of insect-plant interactions, symbiosis, virus vectoring, and the developmental causes of extreme phenotypic plasticity. Here we present the 464 Mb draft genome assembly of the pea aphid Acyrthosiphon pisum. This first published whole genome sequence of a basal hemimetabolous insect provides an outgroup to the multiple published genomes of holometabolous insects. Pea aphids are host-plant specialists, they can reproduce both sexually and asexually, and they have coevolved with an obligate bacterial symbiont. Here we highlight findings from whole genome analysis that may be related to these unusual biological features. These findings include discovery of extensive gene duplication in more than 2000 gene families as well as loss of evolutionarily conserved genes. Gene family expansions relative to other published genomes include genes involved in chromatin modification, miRNA synthesis, and sugar transport. Gene losses include genes central to the IMD immune pathway, selenoprotein utilization, purine salvage, and the entire urea cycle. The pea aphid genome reveals that only a limited number of genes have been acquired from bacteria; thus the reduced gene count of Buchnera does not reflect gene transfer to the host genome. The inventory of metabolic genes in the pea aphid genome suggests that there is extensive metabolite exchange between the aphid and Buchnera, including sharing of amino acid biosynthesis between the aphid and Buchnera. The pea aphid genome provides a foundation for post-genomic studies of fundamental biological questions and applied agricultural problems.
