Estudo bibliográfico e bibliométrico sobre o uso de bactérias endofíticas como indutoras do crescimento de plantas nativas da Caatinga

Abstract

Due to the strong anthropic pressures in the last decades,often with the use of chemical fertilizers, the soil is negatively affected, resulting in the increase of degraded areas. This reality makes essential to understand the natural mechanisms that can be used in the recovery of these areas.Plant growth-promoting endophytic bacteria can promote more efficient growth of native plants, mitigating the negative effects on the soil.This work aimed to survey information in the scientific literature by analyzing and discussing concepts and applications in plant-bacteria interactions, in addition to the mechanisms that establish the processes responsible for promoting growth triggered by the presence of endophytic bactéria. The survey focused on the production of phytohormones, such as indole acetic acid, which is one of the main vegetable auxins.Some methodologies for disinfecting plant material was compiled to show variations in the process of excluding surface bacteria, so that would only beaccessed by endophytic bacteria.The present study aimed to analyze the literature on endophytic bacteria that promote plant growth, indicating its use for the recovery of degraded areas in the caatinga biome.Publication data on the topic in the last 30 years, obtained from the bibliographic review, were discussed, revealing the increase in publications and citations in the area, with China, India and Brazil respectively leading the number of publications, mainly focused on the area of agriculture. However, there are still few works associated with the semi-arid climate, and more research on local peculiarities must be carried out.
