Abstract
Hypothesis: Arabidopsis thaliana specimens germinated in isolated soil bacteria will exhibit positive growth characteristics and rates. Background: Arabidopsis thaliana is a small flowering plant in the family, Brassicaceae. The characteristic short lifecycle and other qualities make this model plant for scientific research.1 Nitrogen is very limited in a usable form for plants in most soils. The liberation of nitrogen from the environment is essential for the plants' survival. Nitrogen fixation is done by soil micro-organisms that break apart nitrogenous compounds into simple, assimilable forms of this essential nutrient. Introduction of soil microorganisms is in agricultural to ensure an ample supply of nitrogen containing compounds to improve crop yield. Four ecotypes: Kas-1 (India), Col-0 (USA), Rsch-4 (Russia), and Bs-5 (Switzerland) were used to test the resulting growth with respect to ecotype and origin. Biomass produced from measured using Kas-1 at varying temperatures. Four ecotypes allow for genetic variation to be considered when analyzing the collected results.
