“…In plants, microRNAs (miRNAs) are transcriptionally modulated by endogenous and surrounding environmental cues [ 7 ]. Most miRNAs are efficiently involved in adjusting the perception/signaling of phytohormones, as well as regulating plant growth and development through transcriptional and posttranscriptional regulations of a multitude of target genes [ 8 ].…”

“…Most miRNAs are efficiently involved in adjusting the perception/signaling of phytohormones, as well as regulating plant growth and development through transcriptional and posttranscriptional regulations of a multitude of target genes [ 8 ]. Some miRNAs play a significant role in adapting plants to different types of environmental stresses [ 7 , 8 ].

In this regard, microRNA172 (miR172) is one of the most important miRNAs playing critical roles in controlling developmental programs, particularly at the flowering phase, as well as in conferring stress tolerance [ 8 , 9 ].…”

This study attempted to address molecular, developmental, and physiological responses of tomato plants to foliar applications of selenium nanoparticles (nSe) at 0, 3, and 10 mgl-1 or corresponding doses of sodium selenate (BSe). The BSe/nSe treatment at 3 mgl-1 increased shoot and root biomass, while at 10 mgl-1 moderately reduced biomass accumulation. Foliar application of BSe/nSe, especially the latter, at the lower dose enhanced fruit production, and postharvest longevity, while at the higher dose induced moderate toxicity and restricted fruit production. In leaves, the BSe/nSe treatments transcriptionally upregulated miR172 (mean = 3.5-folds). The Se treatments stimulated the expression of the bZIP transcription factor (mean = 9.7-folds). Carotene isomerase (CRTISO) gene was transcriptionally induced in both leaves and fruits of the nSe-treated seedlings by an average of 5.5 folds. Both BSe or nSe at the higher concentration increased proline concentrations, H2O2 accumulation, and lipid peroxidation levels, suggesting oxidative stress and impaired membrane integrity. Both BSe or nSe treatments also led to the induction of enzymatic antioxidants (catalase and peroxidase), an increase in concentrations of ascorbate, non-protein thiols, and soluble phenols, as well as a rise in the activity of phenylalanine ammonia-lyase enzyme. Supplementation at 3 mgl-1 improved the concentration of mineral nutrients (Mg, Fe, and Zn) in fruits. The bioaccumulated Se contents in the nSe-treated plants were much higher than the corresponding concentration of selenate, implying a higher efficacy of the nanoform towards biofortification programs. Se at 10 mgl-1, especially in selenate form, reduced both size and density of pollen grains, indicating its potential toxicity at the higher doses. This study provides novel molecular and physiological insights into the nSe efficacy for improving plant productivity, fruit quality, and fruit post-harvest longevity.

“…Fruit development is a sequential process, which involves fruit set, fruit growth and fruit ripening (Osorio et al, 2013). During fruit development, each step is strictly regulated by complex molecular mechanisms, posttranscriptional regulation by microRNAs is one of the important ways (Farinati et al, 2020). At present, most of our knowledge about the genetic and molecular mechanisms of fruit ripening comes from the model plant, tomato (Gao et al, 2015).…”

To understand the molecular characteristics of the miR477 gene family of grape (Vvi-miR477) and to predict its target genes, the Vvi-miR477 genes were identified from previous small RNA sequencing data, then phylogenetic analysis and prediction of target gene were conducted. The Vvi-miR477 family consists of two precursor sequences and three mature sequences. The miR477 family members were mostly 19-22nt in length. The sequence is relatively conservative. Vvi-MIR477a and Vvi-MIR477b are located on chromosomes 1 and 2, respectively. These precursor sequences can form the typical stable stem-loop structure. Their minimum folding free energy is −39.10 kcal/mol and −50.90 kcal/mol, respectively. The MIR477 family can be divided into three groups. The prediction of target genes showed that Vvi-miR477 targets 26S proteasome, DEAD-box, GRAS family protein, Protein Phosphatase 2C, etc. The GO function of target genes was mainly enriched to six categories. The catabolic process, carboxylic ester hydrolase activity is shown to be high. This study provided a theoretical basis for further exploration of the molecular mechanism of miR477 in grape berry ripening.
