Abstract

Water stress can cause a high problem to the crop field and limitation on plant growth in the whole world. Corn is one of the bigger crops produced in Brazil that together with Soybean are responsible for 15% of GDP. Water is essential for the plant, and when a crop is submitted to lost water during the planting period that can be directly related to grain yield decrease. Thus, it is important to develop technology to mitigate the without water and encourage the production in some areas that are affected. Some studies show a symbiosis between plant - bacteria can decrease the damage caused by water stress resulting in increased the production field yield submitted this condition. Microorganism adapted to extreme condition like salinity, water stress, high temperature can be a biotechnology source to agriculture. The Caatinga biome is an important inhabitant for this microorganism adapted to environmental characterized to large period without rains and high temperature as 51 °C in the summer. The objective this study is evaluation of osmotolerant rhizobacteria from Caatinga plants (Cereus jamacaru) against water stress in corn crop.
