Plant Growth Promoting Endophytic Fungal Association from Cajanus cajan, Linn. Plant which Can Improve Plant Growth Promotion

Endophytic microorganisms are little known for exogenous secretion of Plant growth regulator (PGR) and mitigation of salinity stress, which is a major limiting factor for agriculture production worldwide. Endophytic mycoflora are that dwell within robust plant tissues by having a symbiotic association. They are ubiquitously associated with all plants studied till date. Some endophytes are commonly found belonging to the genera Aspergillus sp., Drechlsera sp., Colletotrichum sp., Phomopsis sp., Gliomastix sp., Cladosporium sp., Trichoderma sp., and so forth. Endophytic population is greatly affected by climatic conditions in which they grows. They produce a wide range of compounds useful for plants for their growth. They are also found to have some important role in nutrient cycling, biodegradation, and bioremediation. In this review, we have tried to design the isolate phytohormone producing endophytic fungus from the roots, stems and leaves of Cajanus cajan, Linn., plant and identify its role in plant growth promotion. This study also suggests that these endophytic mycoflora can be used as bio - fertilizer in the agricultural fields. Because extensive use of artificial fertilizers, cause deterioration of environment and have hazardous effects for plants. Artificial fertilizers are very costly and must be supplied continuously to the fields while endophytic fungi stay in the field for years and safe to the plant and environment.
