“…By means of transgenic approaches it was established 9 that miR167 acts as transcriptional regulator in response to bacterial infection (Jodder, Basak, Das & Kundu, 2017) and temperature-induced stress in tomato plants (Jodder et al, 2018). Multiple evidences obtained by both sRNA-sequencing and transgenic approaches, support the role of members of the miR319-family, an ancient miRNA conserved across plant species ranging from mosses to higher plants, as a key modulator of the plant-environment interrelation (at biotic and abiotic level) in monocotyledonous and dicotyledonous species (Bustamante et al, 2018;Liu et al, 2019;Shi et al, 2019;Wu, Qi, Meng & Jin, 2020;Fang et al, 2021;Joshi, Chauhan & Das, 2021). Finally, regarding miR398 and miR408 families, it was recently proposed that these conserved miRNAs, involved in the maintenance of the cooper homeostasis in plants, might be also involved in the systemic signaling of the response to biotic and abiotic stresses (Burkhead et al, 2009;Sanz-Carbonell, Marques, Martinez & Gomez, 2020).…”

Climate change has been associated with a higher incidence of combined adverse environmental conditions that can promote a significant decrease in crop productivity. However, knowledge on how a combination of stresses might affect plant development is still scarce. MicroRNAs (miRNAs) have been proposed as potential targets for improving crop-productivity. Here, we have combined deep-sequencing, computational characterization of responsive miRNAs and validation of their regulatory role in a comprehensive analysis of melon response to several combinations of four stresses (cold, salinity, short day, and infection with a fungus). Twenty-two miRNA families responding to double and/or triple stresses were identified. The regulatory role of the differentially expressed miRNAs was validated by quantitative measurements of the expression of the corresponding target genes. A high proportion (ca. 60%) of these families (mainly highly conserved miRNAs targeting transcription factors) showed a non-additive response to multiple stresses in comparison with that observed under each one of the stresses individually. Among those miRNAs showing non-additive response to stress-combinations, most interactions were negative suggesting the existence of functional convergence in the miRNA-mediated response to combined stresses. Taken together, our results provide compelling evidences that the response to combined stresses cannot be easily predicted from the study individual stresses

“…However, the changes observed in miR319 level were not associated to antagonist alterations in the accumulation of their regulatory targets. It is well established that TEOSINTE BRANCHED1/CYCLOIDEA/PROLIFERATIN CELL FACTOR (TCP) mRNA is a highly conserved target of miR319 in diverse plant species (99) and accumulating evidence has revealed that miR319-regulated TCP (MRTCP) genes participate extensively in plant development by regulating hormone metabolism mediated signaling (100). Interestingly, it has been previously reported that tomato plants infected with PSTVd (another member in the Pospiviroidae family) exhibit a complex array of changes affecting hormone signaling (30).…”

Constricted by an extreme biological simplicity, viroids are compelled to subvert host regulatory networks in order to accomplish their infectious process. Most of the studies focused on the response to viroid infection have only addressed a specific host regulatory level and considered a unique infection time. Thus, much remains to be done if we want to understand the temporal evolution and complex nature of viroid-host interactions. Here we present an integrative analysis of the timing and intensity of the genome-wide alterations in cucumber plants infected with Hop stunt viroid (HSVd). Differential host transcriptome, sRNAnome and methylome were integrated to determine the temporal response to viroid-infection. Our results support that HSVd promotes a dynamic redesign of the cucumber regulatory pathways predominantly affecting specific regulatory layers at different infection phases. Remarkably, the initial response was characterized by a reconfiguration of the host transcriptome by differential exon usage, followed by a predominant down-regulation of the transcriptional activity possibly modulated by the host epigenetic changes associated to infection and characterized by an increased hypermethylation. The silencing of at least three cucumber transcripts potential targets of vd-sRNAs was also observed. The alteration in host sRNA and miRNA metabolism was marginal. We expect that these data constituting the first comprehensive map of the cucumber-response to HSVd could contribute to elucidate the molecular basis of the host alterations triggered by viroid infection.
