Abstract

Brazil's agriculture is pioneer in the world. Together with other countries, Brazil is a food supplier on a global scale. To attend this demand the country passed by an important modernization in the field, and obtained very satisfactory results in terms of increasing its productivity. However, one of the negative aspects associated with this increase is the abusive use of pesticides and fertilizers. Since 2008 the country leads the ranking of countries that use more pesticides on its crops in the world, which has become a public health and environmental concern due the toxicity and recalcitrance of these compounds. Every day the search for alternatives to the use of pesticides and chemical fertilizers grows, once they are toxic and harmful to living beings. The great challenge to be faced is to achieve increased productivity so as not to harm the environment. In this context, the study of microorganisms is promising because it is known that these living beings are a great genetic heritage which houses metabolic pathways of great interest to many human activities, including agriculture. The micro-organisms interact in different ways with plants benefiting them and providing resources for themselves in return, establishing a relationship sometimes mutualistic. They can act to improve the supply of nutrients, defense mechanisms and growth promotion in conditions of biotic and abiotic stress. Optimize and enhance these characteristics by genetic engineering techniques and / or other processes of modern biology are large steps to be taken in efforts to reduce the use of agricultural inputs for the establishment of a production process increasingly sustainable. Thus, this study aims to characterize genes of the fungus Paecilomyces of interest in plant growth promotion, specifically genes coding for enzymes that work in the solubilization of nutrients such as phosphatases, and to combat pathogens such as chitinase, and also to test their efficiency in enhancing crop production.
