العلاقة التكافلية بين النباتات و الكائنات الحية الدقيقة الداخلية كمحفزات للنمو و عوامل مقاومة للأمراض دراسة مقارنة و مراجعة

Abstract

This study was conducted with the aim of identifying the positive effect of the symbiotic relationship between plants and internal microorganisms (endophytes) as biological disease control agents and growth stimulants. Studies indicated the possibility of exploiting them as vital alternatives to chemical fertilizers . The results obtained showed the ability of internal microorganisms to enhance plant growth. Stimulating his immune system by producing plant hormones such as auxins (IAA), which work on cell division and differentiation, suppressing pathogens by producing secondary metabolites (alkaloids, phenols, terpenes...) and stimulating new antibiotics and producing Siderophores. These organisms can also be used for phytoremediation of environmental pollutants and control of fungal diseases by producing hydrolytic enzymes such as chitinase and cellulase ...
