We previously reported that the response of ANR1 expression in shoots to nitrogen (N) starvation and resupply was different from its response in roots. However, how the other root-expressed MADS box genes respond to different N fluctuations in the shoot, and how these MADS box genes respond to complete nutrient fluctuations in the root, were unknown. Results from this study have shown that some members of these root-expressed MADS box genes have different responses in the shoot and root to N treatments, whereas others have similar responses or no responses to the N treatments. Among these 12 root-expressed MADS box genes, AGL16 was the only gene to show a similar response to N fluctuation in both shoots and roots in the same way as ANR1. Results from this study have also shown that ANR1, AGL12, AGL16, AGL19, and SOC1 responded to changes of the complete nutrient condition, which might indicate that they could play key roles in general nutrient stress. These novel findings will help us to further characterize these 12 MADS box genes to uncover the complex regulatory networks that integrate plant responses to changes in nutrient availability.

Abstract 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.

Mads Box Gene

BACKGROUND: Black raspberry is a vital fruit crop with a high antioxidant function. MADS-box genes play an important role in the regulation of fruit development in angiosperms. OBJECTIVE: To understand the regulatory role of the MADS-box family, a total of 80 MADS-box genes were identified and analyzed. METHODS: The MADS-box genes in the black raspberry genome were analyzed using bioinformatics methods. Through an analysis of the promoter elements, the possible functions of different members of the family were predicted. The spatiotemporal expression patterns of members of the MADS-box family during black raspberry fruit development and ripening were systematically analyzed. RESULTS: The genes were classified into type I (Mα: 33; Mβ: 6; Mγ: 10) and type II (MIKC *: 2; MIKCC: 29) genes. We also obtained a complete overview of the RoMADS-box gene family through phylogenetic, gene structure, conserved motif, and cis element analyses. The relative expression analysis showed different expression patterns, and most RoMADS-box genes were more highly expressed in fruit than in other tissues of black raspberry. CONCLUSIONS: This finding indicates that the MADS-box gene family is involved in the regulation of fruit ripening processes in black raspberry.
