Introduction
Several bacterial genera, called plant growth promoting bacteria (PGPB, Bashan and Holguin 1998), stimulate plant growth and yield in cereals, legumes, and other crops (Okon and Labanderas-Gonzalez 1994; Glick et al. 2001). Some strains of Azospirillum lipoferum and Azospirillum brasilense colonize the interior of wheat (Bashan et al. 2004), maize (Lucangeli and Bottini 1996), and rice (Cassan et al. 2001a, 2001b), and therefore are endophytic. One of the major effects attributed to Azospirillum spp. is the augmentation of the physiologically active root surface (Sarig et al. 1988; Steenhoudt and Vanderleyden 2000), and among the mechanisms proposed ...
