Published: Feb. 25, 2022

To complete their life cycles, plants require several minerals that are found in soil. Plant growth and development can be affected by nutrient shortages or high availability. Several adaptations evolutionary changes have enabled to cope with inappropriate conditions low levels. MicroRNAs (miRNAs) been recognized for transcript cleavage translational reduction, used post-transcriptional regulation. Aside from regulating plant development, miRNAs play a crucial role plant’s adverse environmental conditions. Additionally, involved plants’ sensory functions, uptake, long-distance root transport, physiological functions related nutrients. It may possible develop crops cultivated soils either deficient nutrients extreme supplies understanding how associated stress. In this review, an overview is presented regarding recent advances the of responses nitrogen, phosphorus, potassium, sulfur, copper, iron, boron, magnesium, manganese, zinc, calcium deficiencies via miRNA We conclude future research directions emphasizing modification improving food security.
