    Engineering Natural Competence into the Fast-growing Cyanobacterium Synechococcus elongatus UTEX 2973

    Full text link
    Synechococcus elongatus UTEX 2973 is the fastest growing cyanobacterium discovered to date. Using water, carbon dioxide, and light alone, this organism can double in 1.5 hours under optimal conditions. The accelerated doubling exhibited by Synechococcus 2973 makes it a prime candidate to serve as a model photoautotrophic system. However, Synechococcus 2973 lacks one highly desirable feature: it cannot undergo natural transformation. This thesis seeks to engineer this capacity into this fast-growing system in order to create an organism that is both fast growing and naturally competent. Synechococcus 2973 is a unique platform because it is \u3e99% genetically identical to another model cyanobacterium, Synechococcus elongatus PCC 7942, which is naturally transformable. However, this sister system grows much slower (doubling in 4 hours under optimal conditions). In this thesis, a CRISPR/Cas genome editing system was developed for cyanobacteria to allow polymorphic alleles from Synechococcus 7942 to be substituted into Synechococcus 2973 to introduce natural competence to the fast-growing strain. After developing this system, this strategy was used to identify the loci that give rise to the accelerated growth phenotype. Additionally, RNA-sequencing analysis was performed to identify transcriptome differences between Synechococcus 2973 and Synechococcus 7942. With this information in hand, further analysis was performed to identify specific polymorphic loci that give rise to differential natural competence between the two strains. This approach identified two genetic loci that are required to introduce natural competence into Synechococcus 2973: structural transformation pilus component pilN and circadian transcriptional master regulator rpaA. Unfortunately, this engineered strain grew at a reduced rate (doubling in \u3e4 hours), therefore, a directed evolution strategy was used to select against slow growth and to ultimately generate the Synechococcus 2973-T strain. This strain is both fast-growing and naturally transformable and will be an asset for researchers seeking a photoautotrophic model system with these features

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
