Here we performed a broad scale survey data to study whether the distribution patterns and the incidence of vertically-transmitted endophytes in populations of two native grasses from South-America, Poa lanuginosa Poir. and Poa bonariensis (Lam.) Kunth., are associated with environmental characteristics. We also characterized the endophytes from different populations to establish if the genotype of the endophytes is also correlated with environmental variables. The incidence of endophytes ranged from 0 to 100% in both host species. In P. lanuginosa, endophytes were only found in populations on sandy coastal dunes and their incidence was positively associated with winter regime rainfall and soil water availability in the growing season. In P. bonariensis, endophytes were only found in populations in xerophytic forests and their incidence was highly associated with plant community. The distributions of infested populations suggested that the endophytes are not found in those areas with the most favorable or most stressing growth conditions accordingly to climatic or edaphical characteristics. Only the vertically transmitted hybrid endophyte species Neotyphodium tembladerae was detected in both host species. Under the hypothesis of vertical transmission, these results suggested that the endophyte should have been lost in endophyte free populations but is maintained in populations established in environments presenting moderate stress as salinity or short drought periods.
