Other studies of endophyte–plant cooperation in stressful conditions reveal good
results. For example, endophytes help pepper plants tolerate nitrogen deficiency
conditions (Fig. 6.4). In other studies, resistant endophyte species were detected
in the seeds of C4 and CAM plants from resistant strains of C4 and CAM plants
of the phylum Firmicutes. These bacteria are known to be involved in the thermal
