A recent study by Embrapa Agrobiology revealed that the new bacterium is able to Microvirga vignae nodular cowpea and fix nitrogen , so that increases the grain yield by up to 200 percent. The research was published in the International Journal of Systematic and Evolutionary Microbiology - an official vehicle for the registration of new genera and species of microorganisms .
For the researcher Jerri Zilli , which integrates the study staff know the bacteria is important because it opens the possibility of producing a new inoculant highly profitable for cowpea .
The field tests were made with different bacteria identified since the 1990s and part of the germplasm bank of Embrapa Agrobiology . The researcher Gustavo Xavier explains that , as the work progressed, the team realized that one of them belonged to a new species and it would be necessary to describe it scientifically. " The importance of this work has implications for Embrapa that translate into new grounds in the advancement of knowledge and innovation in assets primarily for Portfolio FBN " he says.
The research was an essential step to know the bacteria , but studies do not stop there . Researchers want to know more about the interaction of the organism with the plant cowpea . According to the researcher José Ivo Baldani , was held recently the sequencing of the genome of this strain in partnership with UFPR ( Federal University of Paraná ) . The study should provide important information that can impact the advancement of knowledge about the bacteria itself and its symbiosis with the host plant .
