“…miRNAs are a class of 21-24 nucleotides (nt) non-coding RNAs that are ubiquitously present in both plants and animals [3,[21][22]24]. It has been shown that miRNAs control the expression of their target gene at the posttranscriptional through complementary base pairing [3,[21][22]24]. Although there are some similarities between plant and animal miRNAs, in contrast, there are also notable distinctions in terms of their biogenesis, mechanism of action, and evolution [3,[21][22]24].…”

“…miRNAs regulate the expression of the target gene at post-transcription as well as a translational level [3,[21][22][23][24]. As a result, it is predicted that more than 60% of human protein-coding genes have at least one conserved miRNA binding site as well as various non-conserved sites [25].…”

Food quality and dietary habits have a significant impact on human health. Growing evidence suggests that miRNAs have been extensively detected in various dietary sources, including plants and animals. miRNAs are a class of small non-coding RNA that regulates gene expression in a sequence-specific manner and modulates various biological processes. These dietary miRNAs are transported through the circulatory system and affect the expression of the gene in the recipient cells through a process called cross-kingdom regulation of the gene. This review will provide insight into the role of dietary miRNAs, their stability and transport mechanisms, as well as their impact on human health. Likewise, we update and discuss the future consequences of dietary miRNAs and their possible use in the treatment of various human diseases.

Root system architecture plays an important role in plant adaptation to drought stress. The root system architecture (RSA) consists of several structural features, which includes number and length of main and lateral roots along with the density and length of root hairs. These features exhibit plasticity under water‐limited environments and could be critical to developing crops with efficient root systems for adaptation under drought. Recent advances in the omics approaches have significantly improved our understanding of the regulatory mechanisms of RSA remodeling under drought and the identification of genes and other regulatory elements. Plant response to drought stress at physiological, morphological, biochemical, and molecular levels in root cells is regulated by various phytohormones and their crosstalk. Stress‐induced reactive oxygen species play a significant role in regulating root growth and development under drought stress. Several transcription factors responsible for the regulation of RSA under drought have proven to be beneficial for developing drought tolerant crops. Molecular breeding programs for developing drought‐tolerant crops have been greatly benefitted by the availability of quantitative trait loci (QTLs) associated with the RSA regulation. In the present review, we have discussed the role of various QTLs, signaling components, transcription factors, microRNAs and crosstalk among various phytohormones in shaping RSA and present future research directions to better understand various factors involved in RSA remodeling for adaptation to drought stress. We believe that the information provided herein may be helpful in devising strategies to develop crops with better RSA for efficient uptake and utilization of water and nutrients under drought conditions.

SummarySubmergence induced hypoxic condition is one of the abiotic stresses which negatively affects the plant growth and development, and causes early onset of senescence. Hypoxic conditions ateres the expression of a number of non-coding microRNAs (miRNAs), besides protein-coding genes. However, the molecular function of stress-induced miRNA in submergence induced physiological or developmental changes and recovery remains to be understood. The expression of miR775 is highly induced under hypoxic stress conditions. Here, we show that miR775 is a potential post-transcriptional regulator number of targets, including Galactosyltransferase (GALT9). The expression of miR775 and target GALT9 was significantly induced and reduced respectively at 24 hours of submergence. The overexpression of miR775 (miR775-Oe) confers enhanced recovery from submergence stress and reduced accumulation of ROS, in contrast to wild type and endogenous target mimic of miR775 (MIM775) Arabidopsis plants. We observed a similar recovery phenotype in case of target galt9 mutant plants, indicating the role of miR775-GALT9 module in recovery from submergence. Further, we showed that the expression of SENESCENCE ASSOCIATED GENES (SAGs), such as SAG12, SAG29, and ORE1. was increased in MIM775 and reduced in miR775-Oe and galt9 plants. Thus, our results suggest that miR775-GALT9 module plays a crucial role in the recovery from submergence by modulating the expression of SAGs through differential accumulation of ROS.
