Drought stress genetic mediation mechanism of arbuscular mycorrhiza fungi (AMF)

Abstract

Plant development and productivity are adversely impacted by drought, a severe and complicated abiotic stress. Many research endeavors seek to identify the primary modulators of molecular and biochemical mechanisms linked to drought stress tolerance response. The development of drought stress tolerance involves the induction of several genes with diverse roles. AMF-induced production of drought-responsive genes in plants, such as aquaporins, dehydrins, and transcription factors involved in water transport, osmotic adjustment, and stress regulation. Therefore, in this review, we emphasized these three droughts-related genes. We also discussed the roles played by phytohormones, especially the strigolactone and abscisic acid as signaling molecules that help in the colonization process.
