“…MiR167 has also been implicated in plant immunity. MiR167 is down-regulated in response to fungal infection in Arabidopsis 104 and during bacterial stress, miR167 alters the expression of genes of the host auxin signaling pathway, including ARF6/8 105 .…”

Small RNAs (sRNAs) have been recently recognized as key genetic and epigenetic regulators in various organisms, ranging from the modification of DNA and histone methylations to the modulation of the abundance of coding or non-coding RNAs. In plants, major regulatory sRNAs are classified as respective microRNA (miRNA) and small interfering RNA (siRNA) species, with the former primarily engaging in posttranscriptional regulation while the latter in transcriptional one. Many of these characterized sRNAs are involved in regulation of diverse biological programs, processes, and pathways in response to developmental cues, environmental signals/stresses, pathogen infection, and pest attacks. Recently, sRNAs-mediated regulations have also been extensively investigated in horticultural plants, with many novel mechanisms unveiled, which display far more mechanistic complexity and unique regulatory features compared to those studied in model species. Here, we review the recent progress of sRNA research in horticultural plants, with emphasis on mechanistic aspects as well as their relevance to trait regulation. Given that major and pioneered sRNA research has been carried out in the model and other plants, we also discuss ongoing sRNA research on these plants. Because miRNAs and phased siRNAs (phasiRNAs) are the most studied sRNA regulators, this review focuses on their biogenesis, conservation, function, and targeted genes and traits as well as the mechanistic relation between them, aiming at providing readers comprehensive information instrumental for future sRNA research in horticulture crops.

“…And eight microRNAs were found to target on the ve TaCCoAOMT genes in the Fg infection related modules, including tae-miR167a and tae-miR1119. Previous studies had been reported that miR167a could meditate auxin signaling to respond to biotic stresses in tomato [31], and miR1119 was proven to regulate the expression of actin under stress conditions and activate plant defense signaling pathway in barley [32]. We postulated that these two miRNAs also play the regulatory role in the response to Fg infection through regulating on CCoAOMT genes in wheat.…”

Background Lignin is one of the main components of cell wall, which directly associates with the development and defense mechanisms in plants, especially in response to Fusarium head blight (FHB) tolerance. Caffeoyl-coenzyme A Omethyltransferase (CCoAOMT) is the main regulator determining the efficiency of lignin synthesis and composition. Although it has been widely characterized in many plants, the importance of CCoAOMT family in wheat is not well understood up to now. Results Here, a total 21 CCoAOMT genes were identified in wheat (TaCCoAOMT) through a in silico genome search method and they were classified into four groups based on phylogenetic analysis with the members in the same group sharing similar gene structures and conserved motif compositions. Furthermore, the expression patterns and co-expression network which these TaCCoAOMT involved in were comprehensively investigated using 48 RNA-seq samples from Fusarium graminearum-infected and control samples of 4 wheat genotypes. Combined with qRT-PCR validation of 11 Fg-responsive TaCCoAOMT genes, the potential candidates involving in FHB response and their regulation modules were preliminarily revealed. Additionally, we also investigated the genetic diversity and main haplotypes of these CCoAOMT genes in bread wheat and its relative populations based on resequencing data. Conclusion This study systematically identified and characterized the CCoAOMT gene family in wheat, which not only provided the targets for further functional analysis, but also contribute to the mechanism of lignin biosynthesis and its role in FHB tolerance in wheat and beyond.

Furthermore, the expression patterns and co-expression network in which TaCCoAOMT is involved were comprehensively investigated using 48 RNA-seq samples from Fg infected and mock samples of 4 wheat genotypes. Combined with qRT-PCR validation of 11 Fg-responsive TaCCoAOMT genes, potential candidates involved in the FHB response and their regulation modules were preliminarily suggested. Additionally, we investigated the genetic diversity and main haplotypes of these CCoAOMT genes in bread wheat and its relative populations based on resequencing data.
