Enumeration of Culturable Endophytic Bacterial Population of Different Lycopersicum esculentum L. Varieties

Endophytes are the microbes, which reside inside the plants without causing any harm. They colonize the internal plant tissues and form a different range of interaction including symbiotic and trophobiotic. Such bacteria promote plant growth and also act as biocontrol agents. In some cases endophytes also applied as biological agents like nanoparticles in controlling human diseases including cancer (Ryan et al., 2008; Beiranvand et al., 2017). The endophytic niche protects from the environmental stresses to those bacteria that colonize and establish in the plant. Although root is the most obvious site of entry for many endophytes, they may also occur through aerial plant parts. The diversity of endophytic microorganisms in the host plants includes both gram-positive and gram-negative which from various genera of α-, β-, and γproteobacteria, Actinobacteria, Firmicutes and bacteroidetes. Their presence within the plant can be detected by cultural or molecular methods (Rosenblueth and Martínez-Romero, 2006).
