“…AtTCP1 was a member of CYC/TB1 clade, which could affect the synthesis of brassinosteroids and elongation of the stem (Guo et al, 2010;Koyama et al, 2010). Members of the CIN clades are targeted by microRNA miR319, and they affect cell differentiation in Arabidopsis (Koyama et al, 2007;Zhou and Luo, 2014). Some members perform the function of negative regulators that affect the growth of leaf margin (Palatniket al, 2003).…”

ABSTRACT. The TCP family is a transcription factor family, members of which are extensively involved in plant growth and development as well as in signal transduction in the response against many physiological and biochemical stimuli. In the present study, 61 TCP genes were identified in tobacco (Nicotiana tabacum) genome. Bioinformatic methods were employed for predicting and analyzing the gene structure, gene expression, phylogenetic analysis, and conserved domains of TCP proteins in tobacco. The 61 NtTCP genes were divided into three diverse groups, based on the division of TCP genes in tomato and Arabidopsis, and the results of the conserved domain and sequence analyses further confirmed the classification of the NtTCP genes. The expression pattern of NtTCP also demonstrated that majority of these genes play important roles in all the tissues, while some special genes exercise their functions only in specific tissues. In brief, the comprehensive and thorough study of the TCP family in other plants provides sufficient resources for studying the structure and functions of TCPs in tobacco.

“…As a highly conserved ancient miRNA, miR319 plays important roles in plant development (Jones-Rhoades et al, 2006; Yang et al, 2013; Zhou et al, 2013; Zhou and Luo, 2014). High levels of miR319 or downregulation of its target genes leads to a broader leaf phenotype in arabidopsis (Palatnik et al, 2003), and similar results were found in snapdragons, tomatoes, rice, and other plants (Ori et al, 2007; Yang et al, 2013).…”

“…The recent studies showed that overexpression of miR319 led to abnormal development and tolerance to stress in several transgenic plants (Yang et al, 2013; Zhou et al, 2013; Wang et al, 2014; He et al, 2014; Zhou and Luo, 2014; Li et al, 2016). High levels of Osa-miR319 in transgenic rice led to wider leaf blades and significantly enhanced cold tolerance in acclimated transgenic plants (Yang et al, 2013).…”

Due to its high biomass yield, low environmental impact, and widespread adaptability to poor soils and harsh conditions, switchgrass (Panicum virgatum L.), a warm-region perennial herbaceous plant, has attracted much attention in recent years. However, little is known about microRNAs (miRNAs) and their functions in this bioenergy grass. Here, we identified and characterized a miRNA gene, Pvi-MIR319a, encoding microRNA319a in switchgrass. Transgenic rice lines generated by overexpressing the Pvi-MIR319a precursor gene exhibited broader leaves and delayed flowering compared with the control. Gene expression analysis indicated at least four putative target genes were downregulated. Additionally, we cloned a putative target gene (PvPCF5) of Pvi-MIR319a from switchgrass. PvPCF5, a TCP transcription factor, is a nuclear-localized protein with transactivation activity and control the development of leaf. Our results suggest that Pvi-MIR319a and its target genes may be used as potential genetic regulators for future switchgrass genetic improvement.

“…Overexpression of miR319 in creeping bentgrass (Agrostis stolonifera) resulted in the suppression of five target genes, AsPCF5, AsPCF6, AsPCF8, AsTCP14, and the homolog of rice NAC domain gene, AsNAC60. The targeted suppression of these genes has proved to play a positive role in salinity and drought stress tolerance (Zhou and Luo 2014). The authors also depict the possible cross talk between miRNA regulation and phytohormone signaling.…”

MicroRNAs (miRNAs) are a distinct class of non-coding, small regulatory RNAs which have evolved significantly in generating abiotic stress tolerance across a variety of model plants and crop species. These miRNAs, while undergoing post-transcriptional modifications, have often been found to be linked with epigenetic regulations of stress-responsive gene expression. The discovery of isomers of miRNAs (isomiRs) is also a remarkable event, as some schools of scientists believe them to be regulatory molecules distinct from the conventional miRNAs. The link between isomiRs and abiotic stress responses in plants is now a field of intense research. In this review, we have highlighted the mechanism of various tools and techniques which are essential to visualize high-throughput data analysis. Such data are required for generating large-scale libraries of small RNAs, from which stress-responsive miRNAs are conventionally screened. The concluding part of the review especially contains an exhaustive discussion on the recent developments of miRNA-mediated tolerance towards multiple stresses, such as nutrient deficiency, salinity, drought, oxidative stress, hypoxia, temperature stress, radiation, and heavy metal toxicity. Both transgenic as well as miRNAome approaches have been focussed in this section of the review.
