Description Accepted date: 14 October 2020
Abiotic stresses like drought, extreme temperature, and lack of sufficient water or nutrients adversely affect plant growth
and productivity. The physiological responses of higher plants to the environmental stresses are largely influenced by the
root system, which can quickly modulate its developmental pattern under changing water, nutrient, and temperature, as an
adaptive response. Protein coding genes, phytohormones and microRNAs (miRNAs) are among the key players which
imparts crucial intrinsic role in shaping the root development and its environment adaptive growth pattern. Among these
factors, miRNAs belong to a class of small non-coding RNAs of 21–24 nucleotides in length, which regulates various
aspects of plant growth and development by negatively regulating their target genes through either transcriptional cleavage
or translational inhibition. Although many miRNAs have been identified to be differentially regulated under various abiotic
stress conditions, only a limited number of them have been characterized, due to the complex nature of its regulation.
However, some of the miRNAs, such as miR156, miR165/166, miR169 etc., have recently been shown to be involved in
both abiotic stress response and root development, indicating the diverse role of miRNA mediated gene regulation. The
field of miRNA mediated gene regulation is dynamically expanding and more miRNAs are being characterized for their
function. Current review focuses on miRNAs that are differentially regulated by major abiotic stresses as well as are
involved in root development in Arabidopsis thaliana. We highlight their role in regulation of multiple and diverse aspects
of developmental and physiological processes in Arabidopsis.
