Abstract
Seeds contain endophytic bacteria that may be transmitted from generation to generation.
Some of these bacteria can benefit plant growth and defense against abiotic and biotic stresses. Little is known however about the mechanisms of bacterial colonization of seeds and their transmission from generation to generation in host plants. In this study we have demonstrated that individual seeds of maize (Zea mays L.) taken from the same cob and bean seeds (Phaseolus vulgaris L.) from different pods and within individual pods differ in their bacterial content and population diversity.
We suggest that this bacterial variability within seed population of individual plants may contribute to the species adaptation to diverse environments and be harnessed in the production of crop plants.
