MicroRNA393 (miR393) has been implicated in plant growth, development and multiple stress responses in annual species such as Arabidopsis and rice. However, the role of miR393 in perennial grasses remains unexplored. Creeping bentgrass (Agrostis stolonifera L.) is an environmentally and economically important C3 cool-season perennial turfgrass. Understanding how miR393 functions in this representative turf species would allow the development of novel strategies in genetically engineering grass species for improved abiotic stress tolerance. We have generated and characterized transgenic creeping bentgrass plants overexpressing rice pri-miR393a (Osa-miR393a). We found that Osa-miR393a transgenics had fewer, but longer tillers, enhanced drought stress tolerance associated with reduced stomata density and denser cuticles, improved salt stress tolerance associated with increased uptake of potassium and enhanced heat stress tolerance associated with induced expression of small heat-shock protein in comparison with wild-type controls. We also identified two targets of miR393, AsAFB2 and AsTIR1, whose expression is repressed in transgenics. Taken together, our results revealed the distinctive roles of miR393/target module in plant development and stress responses between creeping bentgrass and other annual species, suggesting that miR393 would be a promising candidate for generating superior crop cultivars with enhanced multiple stress tolerance, thus contributing to agricultural productivity.

SummarySalinity‐induced accumulation of certain microRNAs accompanied by gaseous phytohormone ethylene production has been recognized as a mechanism of plant salt tolerance. MicroRNA319 (miR319) has been characterized as an important player in abiotic stress resistance in some C3 plants, such as Arabidopsis thaliana and rice. However, its role in the dedicated biomass plant switchgrass (Panicum virgatum L.), a C4 plant, has not been reported. Here, we show crosstalk between miR319 and ethylene (ET) for increasing salt tolerance. By overexpressing Osa‐MIR319b and a target mimicry form of miR319 (MIM319), we showed that miR319 positively regulated ET synthesis and salt tolerance in switchgrass. By experimental treatments, we demonstrated that ET‐mediated salt tolerance in switchgrass was dose‐dependent, and miR319 regulated the switchgrass salt response by fine‐tuning ET synthesis. Further experiments showed that the repression of a miR319 target, PvPCF5, in switchgrass also led to enhanced ethylene accumulation and salt tolerance in transgenic plants. Genome‐wide transcriptome analysis demonstrated that overexpression of miR319 (OE‐miR319) down‐regulated the expression of key genes in the methionine (Met) cycle but promoted the expression of genes in ethylene synthesis. The results enrich our understanding of the synergistic effects of the miR319‐PvPCF5 module and ethylene synthesis in the salt tolerance of switchgrass, a C4 bioenergy plant.

“…On the basis of full length amino acid sequence conserved domain and similarity, we subdivided the 171 typical members of the MADS gene family into 5 groups (designated MIKC, Mα, Mβ, Mγ, Mδ), according to the previous classification of MADS proteins from Arabidopsis [9]. Of the 63 inferred physic nut JcMADS proteins, thirty-two were assigned to group MIKC (JcMADS03, 04, 05, 07, 12,16,17,19,20,22,24,25,26,27,28,29,31,32,37,38,42,44,46,47,49,50,52,53,54,55,56,63), thirteen to group Mα (JcMADS01, 06, 08, 11,13,14,33,35,39,43,57,58,59), four to group Mβ (JcMADS09, 48, 51, 60), six to group Mγ (JcMADS10, 15,34,36,41,62) and eight to group Mδ (JcMADS02, 18,21,23,30,40,45,…”

Background: Physic nut (Jatropha curcas), a non-edible oilseed plant, is among the most promising alternative energy sources because of its high seed oil content, rapid growth and extensive adaptability. Proteins encoded by MADS-box genes are important transcription factors involved in the regulation of plant growth, seed development and responses to abiotic stress. However, there has been no in-depth research on the MADS-box genes and their roles in physic nut. Results:In the present study, 63 MADS-box genes (JcMADSs) were identified in the physic nut genome, and classed into five groups (MIKC, Mα, Mβ, Mγ, Mδ) based on phylogenetic comparison with Arabidopsis homologs. Expression profile analysis based on RNA-seq suggested that many JcMADS genes were expressed most strongly in seeds, and seven of them responded in leaves to at least one abiotic stressor (drought and/or salinity) at one or more time points. Transient expression analysis and a transactivation assay indicated that JcMADS05 is a nucleus-localized transcriptional activator.Plants overexpressing JcMADS05 did not show altered plant growth, but the overexpressing plants did exhibit reductions in grain size, grain length, grain width, 1000-seed weight and yield per plant.Further data on the reduced grain size in JcMADS05-overexpressing plants supported the putative role of JcMADS genes in seed development. Conclusions:This study will be useful in understanding the involvement of MADS-box genes in growth and development in addition to their functions in abiotic stress resistance, and will ultimately form the basis for functional characterization and the exploitation of candidate genes for the genetic engineering of physic nut. BackgroundThe regulation of plant growth, development and stress responses is complex and is coordinated by many mechanisms. These mechanisms are under the control of a series of related genes acting through complex regulatory networks. In these processes, transcription factor (such as members of the MYB, HD-Zip, ARF, NAC, MADS-box, and ERF gene families) specifically recognize cis-regulatory elements present in the promoter regions of these genes, and regulate their expression so as to modulate a wide range of biochemical, physiological and developmental processes [1][2][3][4][5][6] (Ferrandiz All Arabidopsis MADS-box protein sequences were used as queries in a BlastP search to identify physic nut proteins. A Hidden Markov Model (HMM) search was also performed against the physic nut protein database using the MADS-domain PF03106. In total, 63 putative MADS proteins were identified in physic nut, with the presence of the MADS-box domain in each of them being confirmed by a SMART website search. These genes were named sequentially from JcMADS01 to JcMADS63 according to their chromosomal locations (Additional File 1). The 63 JcMADS genes ranged in length from 195 (JcMADS35) to 1164 (JcMADS34), thus potentially the proteins encoded would be from 64 to The research was conceived and designed by XB and YT. The experiments were performed ...
