“…miR172 has been the focus of multiple studies using different approaches, such as overexpression, expression of resistant target genes, or mutations in individual loci encoding the miRNA (26)(27)(28)(29)(30)(31)(32)(33)(34)(35). These previous studies suggested that miR172 mainly controls flowering time and floral organ identity.…”

Improvements in plant agricultural productivity are urgently needed to reduce the dependency on limited natural resources and produce enough food for a growing world population. Human intervention over thousands of years has improved the yield of important crops; however, it is increasingly difficult to find new targets for genetic improvement. MicroRNAs (miRNAs) are promising targets for crop improvement, but their inactivation is technically challenging and has hampered functional analyses. We have produced a large collection of transgenic short tandem target mimic (STTM) lines silencing 35 miRNA families in rice as a resource for functional studies and crop improvement. Visual assessment of field-grown miRNA-silenced lines uncovered alterations in many valuable agronomic traits, including plant height, tiller number, and grain number, that remained stable for up to five generations. We show that manipulation of miR398 can increase panicle length, grain number, and grain size in rice. In addition, we discovered additional agronomic functions for several known miRNAs, including miR172 and miR156. Our collection of STTM lines thus represents a valuable resource for functional analysis of rice miRNAs, as well as for agronomic improvement that can be readily transferred to other important food crops.small RNA | microRNA | silencing | yield | crop

“…However, GmTOE4b expression was different from GmTOE4a, and was similar to AtTOE3 in Arabidopsis. It has been demonstrated that miR172-mediated repression of the AtTOE3 gene is critical for both floral transition and floral patterning in Arabidopsis (Jung et al 2014); therefore, GmTOE4b may function similarly to AtTOE3, playing a role in flower development in soybean.…”

“…It was recently reported that TOE3 is critical for both floral transition and floral patterning (Jung et al 2014). Transgenic maize (Zea mays) lines with increased AP2-like gene glossy15 (gl15), which is a target of miR172, not only have more leaves expressing juvenile traits but they also show delayed onset of reproductive development, indicating that gl15 plays a primary role in the maintenance of the juvenile phase (Lauter et al 2005).…”

Dual functions of GmTOE4a in the regulation of photoperiod-mediated flowering and plant morphology in soybean

Flowering time, maturity, and plant morphology have considerable effects on the adaptation and grain yield of soybean (Glycine max). The identification of novel genes and an understanding of their molecular basis are critical to improve soybean productivity. In this study, we cloned a flowering time related APETALA2-like gene GmTOE4a and generated GmTOE4a-overexpressing lines in the cultivar Williams 82. The transgenic lines exhibited late flowering both under long day and short day conditions, and repressed the flowering-related genes, including GmFT2a, GmFT5a, GmAP1, and GmLFY, whereas the flowering repressors GmFT4 and miR156 were upregulated. Interestingly, GmTOE4a was also mediated by photoperiod via maturity genes E3 and E4, which encode photoreceptors in soybean. Further, miR172-mediated GmTOE4a, which regulates flowering in soybean, is different in Arabidopsis in that it is dependent on the CONSTANS-like gene GmCOL1a. In addition to its effect on flowering time, GmTOE4a regulated plant morphology, increased stem thickness, and reduced plant height, internode length and leaf size, which are important agronomic traits that enhance the capacity to resist lodging and increase soybean yield. This is useful information to understand the molecular mechanism of flowering time and plant morphology in soybean and will greatly influence soybean yield improvement.

“…Among the heading date-related miRNAs, miR172 has been reported to be conserved and involved in flowering time and floral patterning by targeting AP2-like transcription factors across the monocotyledons and dicotyledons (30–32). In rice, miR172 was found to be highly expressed in the late vegetative stages and developing panicles.…”

RiceATM: a platform for identifying the association between rice agronomic traits and miRNA expression

et al. 2016

MicroRNAs (miRNAs) are known to play critical roles in plant development and stress-response regulation, and they frequently display multi-targeting characteristics. The control of defined rice phenotypes occurs through multiple genes; however, evidence demonstrating the relationship between agronomic traits and miRNA expression profiles is lacking. In this study, we investigated eight yield-related traits in 187 local rice cultivars and profiled the expression levels of 193 miRNAs in these cultivars using microarray analyses. By integrating the miRBase database, the rice annotation project database, and the miRanda and psRNATarget web servers, we constructed a database (RiceATM) that can be employed to investigate the association between rice agronomic traits and miRNA expression. The functions of this platform include phenotype selection, sample grouping, microarray data pretreatment, statistical analysis and target gene predictions. To demonstrate the utility of RiceATM, we used the database to identify four miRNAs associated with the heading date and validated their expression trends in the cultivars with early or late heading date by real-time PCR. RiceATM is a useful tool for researchers seeking to characterize the role of certain miRNAs for a specific phenotype and discover potential biomarkers for breeding or functional studies.Database URL: http://syslab3.nchu.edu.tw/rice/
