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.

Silver nanoparticles (AgNPs) have been shown to enhance seed germination and plant growth. In this study, we examined the plant response to AgNP dosage using a model plant, Arabidopsis thaliana. Seedlings were treated with different concentrations of AgNPs. Seedling fresh and dry weights were measured for all treatments. The exposure of plants to 1 mg/l AgNPs resulted in a significant increase in seedling fresh and dry weights compared with control plants, although the exposure to lower and higher concentrations resulted in a decrease in fresh and dry weights. Expression profiling for 22 MADS-box genes was carried out using quantitative real-time PCR (qRT-PCR). Among the investigated MADS-box genes, eight genes were upregulated and four genes were downregulated at each of the AgNP concentrations, 0.1 and 1 mg/l. Revealing the effects of AgNPs on the expression of MADS-box genes will increase our knowledge of their role before implementing a large-scale agricultural utilization of AgNPs in the improvement of plant growth and development.
