Conteúdo: 	Sugarcane is a very important crop that grows associated with diazotrophic and plant-hormone-producing endophytic bacteria, such as Gluconacetobacter diazotrophicus, Herbaspirillum seropedicae and H. rubrisubalbicans. In this interaction, bacteria colonize the intercellular spaces and vascular tissues of most plant organs, promoting plant growth without inducing disease symptoms or nodule formation. Probably, pant genetic factors control the process involved in plant colonization by these endophytes. The signaling pathways by with sugarcane plants can decipher bacterial signals and respond properly for a successful association are still not clearly understood. Here, we searched the sugarcane database for all expressed sequence tags (ESTs) preferentially or exclusively expressed in cDNA libraries constructed from sugarcane plants inoculated with G. diazotrophicus and H. rubrisubalbicans. Two such data sets of ESTs were generated in the infected libraries and ESTs from both data sets were functionally organized. For all categories, ESTs candidates to be involved in different processes of plant/bacteria signaling were identified, suggesting that the initial steps of colonization are actively controlled by the plant in the sugarcane/diazotrophic endophyte association.
