“…These characterized ZFPs are involved in plant development ( Li X.J. et al, 2014 ; Seok et al, 2016 ), regulation of plant height ( Liu et al, 2011 ; Sendon et al, 2014 ), root development ( Liu et al, 2013 ), flower development ( Yang et al, 2014 ), seed germination ( Baek et al, 2015 ), secondary wall thickening and anther development ( Chai et al, 2015 ), and fruit ripening ( Weng et al, 2015 ). ZFP family proteins are involved in resistance to biotic stresses, such as rice blast fungus infection ( Li Y. et al, 2014 ; Cao et al, 2016 ).…”

Plant zinc finger proteins (ZFPs) comprise a large protein family and they are mainly involved in abiotic stress tolerance. Although Arabidopsis RING/FYVE/PHD ZFP At5g62460 (AtRZFP) is found to bind to zinc, whether it is involved in abiotic stress tolerance is still unknown. In the present study, we characterized the roles of AtRZFP in response to abiotic stresses. The expression of AtRZFP was induced significantly by salt and osmotic stress. AtRZFP positively mediates tolerance to salt and osmotic stress. Additionally, compared with wild-type Arabidopsis plants, plants overexpressing AtRZFP showed reduced reactive oxygen species (ROSs) accumulation, enhanced superoxide dismutase and peroxidase activity, increased soluble sugars and proline contents, reduced K+ loss, decreased Na+ accumulation, stomatal aperture and the water loss rate. Conversely, AtRZFP knockout plants displayed the opposite physiological changes when exposed to salt or osmotic stress conditions. These data suggested that AtRZFP enhances salt and osmotic tolerance through a series of physiological processes, including enhanced ROSs scavenging, maintaining Na+ and K+ homeostasis, controlling the stomatal aperture to reduce the water loss rate, and accumulating soluble sugars and proline to adjust the osmotic potential.

“…Typically, G‐box and CBS motifs are part of light/circadian regulated gene promoters and usually cooperate in defining the transcript oscillation properties (Michael et al ., 2008). In addition, sequence disruption in the Bay allele may also affect the binding of C2H2 zinc‐finger proteins which are involved in various aspects of normal plant growth and development, as well as in environmental stress tolerance regulation (Sendon et al ., 2014).…”

Fine mapping identifies NAD‐ME1 as a candidate underlying a major locus controlling temporal variation in primary and specialized metabolism in Arabidopsis

Plant metabolism is modulated by a complex interplay between internal signals and external cues. A major goal of all quantitative metabolomic studies is to clone the underlying genes to understand the mechanistic basis of this variation. Using fine-scale genetic mapping, in this work we report the identification and initial characterization of NAD-DEPENDENT MALIC ENZYME 1 (NAD-ME1) as the candidate gene underlying the pleiotropic network Met.II.15 quantitative trait locus controlling variation in plant metabolism and circadian clock outputs in the Bay 3 Sha Arabidopsis population. Transcript abundance and promoter analysis in NAD-ME1 Bay-0 and NAD-ME1 Sha alleles confirmed allele-specific expression that appears to be due a polymorphism disrupting a putative circadian cis-element binding site. Analysis of transfer DNA insertion lines and heterogeneous inbred families showed that transcript variation of the NAD-ME1 gene led to temporal shifts of tricarboxylic acid cycle intermediates, glucosinolate (GSL) accumulation, and altered regulation of several GSL biosynthesis pathway genes. Untargeted metabolomic analyses revealed complex regulatory networks of NAD-ME1 dependent upon the daytime. The mutant led to shifts in plant primary metabolites, cell wall components, isoprenoids, fatty acids, and plant immunity phytochemicals, among others. Our findings suggest that NAD-ME1 may act as a key gene to coordinate plant primary and secondary metabolism in a time-dependent manner.
