1. Proteobacteria. It is the largest and metabolically diverse group known in bacteria. It consist of Gram-negative bacteria. It is the precursor of mitochondria. Bacteria belonging to this group consist of all kind of nutritional types.This phylum further divided into classes of alpha, beta, gamma, delta, epsilon where alpha- proteobacteria belongs to purple non sulfur bacteria; beta- proteobacteria belongs to versatile metabolically active bacteria i.e. chemolithoautotrophs, photoautotrophs, and general heterotrophs; gamma proteobacteria belongs to economically important bacteria, such as the E. coli, pathogenic bacteria, methane oxidizers as well, ;delta mainly belongs to those bacteria which cary out sulfur cycle in anaerobic conditions. 2. two phylas are: planctomycetes and bacteroidetes. Bacteroidetes are associated with both organic as well as GMO roots while planctomycetes is more abundant in GMO root. 3. GMO roots are those which carry a foreign gene in its genome as a result the chemicals or other metabolites produced by GMO root is different from the organic root. That is why the bacterial community is different in GMO root and organic root. 4. Whole genome squencing or pyrosequencing can be done to identify and confirm the bacterial communities present or associated with organic roots as well as GMO roots Solution 1. Proteobacteria.
