“…miRNAs are involved in diverse aspects of plant growth and development ( Mallory & Vaucheret, 2006 ; Sunkar et al, 2007 ). Some of the 26 miRNAs that were always present in 8–11 ELNs according to our bioinformatics analysis were shown to participate in fundamental plant physiological and biochemical processes, such as various stress responses, flowering regulation, sugar accumulation, and root development ( Llave, 2004 ; Dong et al, 2009 ; Khan et al, 2011 ; Kim et al, 2014 ; Sunkar & Zhu, 2004 ; Yu et al, 2015 ; Zhao et al, 2017 ). For example, the MIR-319 family acts on TCP , forming a relationship that has implications for many aspects of floral development ( Nag et al, 2009 ).…”

Edible plant-derived exosome-like nanoparticles (EPDELNs) are novel naturally occurring plant ultrastructures that are structurally similar to exosomes. Many EPDELNs have anti-inflammatory properties. MicroRNAs (miRNAs) play a critical role in mediating physiological and pathological processes in animals and plants. Although miRNAs can be selectively encapsulated in extracellular vesicles, little is known about their expression and function in EPDELNs. In this study, we isolated nanovesicles from 11 edible fruits and vegetables and subjected the corresponding EPDELN small RNA libraries to Illumina sequencing. We identified a total of 418 miRNAs—32 to 127 per species—from the 11 EPDELN samples. Target prediction and functional analyses revealed that highly expressed miRNAs were closely associated with the inflammatory response and cancer-related pathways. The 418 miRNAs could be divided into three classes according to their EPDELN distributions: 26 “frequent” miRNAs (FMs), 39 “moderately present” miRNAs (MPMs), and 353 “rare” miRNAs (RMs). FMs were represented by fewer miRNA species than RMs but had a significantly higher cumulative expression level. Taken together, our in vitro results indicate that miRNAs in EPDELNs have the potential to regulate human mRNA.

“…Arabidopsis plants overexpressing miR168a display abscisic acid hypersensitivity and drought tolerance (Li et al 2012). The overexpression of miR172 promotes leaf length elongation in adult plants and increases root and hypocotyl growth (Kim et al 2014), and miR171 overexpression affects floral meristem determinancy in barley (Curaba et al 2013).…”

The rolB gene activates the expression of genes encoding microRNA processing machinery

The rolB gene of Agrobacterium rhizogenes renders cells more tolerant of environmental stresses and increases their defense potential. However, these effects, coupled with the developmental abnormalities caused by rolB, have not yet been explained. In rolB-transformed Arabidopsis thaliana cells, we detected a 2.2 to 7-fold increase in the expression of genes encoding core and accessory proteins (DCL1, SE, HYL1, AGO1, TGH, DDL, HEN1, AGO4 and RDR2) of the microRNA processing machinery. However, the rolB gene did not affect the expression of DCL2, DCL3 and HST. The diverse and complex effects of rolB on transformed plant cells may be attributable to changes caused by this gene in particular RNA silencing pathways.

“…miRNA is involved in the regulation of brassinosteroids signaling pathway. For example, miR172 increases the sensitivity to BR by affecting the Bak1-mediated BR pathway, and promote seedling hypocotyl elongation and root growth in Arabidopsis thaliana (Kim et al, 2014). Osa-mir1848 regulated the synthesis of phytosterol and BR by splicing the target gene OsCYP51G3.…”

miRNAs as key regulators via targeting the phytohormone signaling pathways during somatic embryogenesis of plants

et al. 2020

Somatic embryogenesis is the regeneration of embryos from the somatic cell via dedifferentiation and redifferentiation without the occurrence of fertilization. A complex network of genes regulates the somatic embryogenesis process. Especially, microRNAs (miRNAs) have emerged as key regulators by affecting phytohormone biosynthesis, transport and signal transduction pathways. miRNAs are small, non-coding small RNA regulatory molecules involved in various developmental processes including somatic embryogenesis. Several types of miRNAs such as miR156, miR157, miR 159, miR 160, miR165, miR166, miR167, miR390, miR393 and miR396 have been reported to intricate in regulating somatic embryogenesis via targeting the phytohormone signaling pathways. Here we review current research progress on the miRNA-mediated regulation involved in somatic embryogenesis via regulating auxin, ethylene, abscisic acid and cytokinin signaling pathways. Further, we also discussed the possible role of other phytohormone signaling pathways such as gibberellins, jasmonates, nitric oxide, polyamines and brassinosteroids. Finally, we conclude by discussing the expression of miRNAs and their targets involved in somatic embryogenesis and possible regulatory mechanisms cross talk with phytohormones during somatic embryogenesis.
