“…Our data identify SnRKs as present in both the adult and juvenile clusters, with a tightly coexpressed early juvenile group of six SnRK3s as especially prominent. No phase-change phenotype has yet been described for SnRK3 mutants, although SnRK1 regulation clearly affects developmental timing; this has been demonstrated by multiple studies in which overexpression delayed flowering and vegetative phase change (Baena-González et al, 2007;Tsai and Gazzarrini, 2012;Williams et al, 2014), and SnRK3s have been demonstrated to interact with SnRK1 in the regulation of sugar responses (Yan et al, 2014). Furthermore, interaction has been shown between SnRKs and the B3 transcription factor FUSCA3, which binds to the promoters of miR156 loci (Gazzarrini et al, 2004).…”

“…Other ABA- related genes ( ABF4, HAB1, HAI2, GBF3, RD26, MYB31, RAP2.3 ) as well as KING1, TPS10, TRE, XERICO, EXL2, KMD3, VOZ1, SIS and PUB19 were expressed in both xylem and phloem ( Figures 5C,D ). In the CLV3/WUS expression domain, we found TEM1 , protein kinase CIPK14 that interacts with SnRK1 (Yan et al, 2014), SUS3, UDP-GLUCOSYL TRANSFERASE 87A2 ( UGT87A2 ) and 6 PHOSPHOGLUCONOLACTONASE 1 (PGL1 ) ( Figure 5E ). The genes PIF1, PIF4, EXL4, ADAGIO (ADO1), ETR2 and COR413 IM1 accumulated preferentially in leaf primordia ( Figure 5F ).…”

A Conserved Carbon Starvation Response Underlies Bud Dormancy in Woody and Herbaceous Species

Plant shoot systems give rise to characteristic above-ground plant architectures. Shoots are formed from axillary meristems and buds, whose growth and development is modulated by systemic and local signals. These cues convey information about nutrient and water availability, light quality, sink/source organ activity and other variables that determine the timeliness and competence to maintain development of new shoots. This information is translated into a local response, in meristems and buds, of growth or quiescence. Although some key genes involved in the onset of bud latency have been identified, the gene regulatory networks (GRNs) controlled by these genes are not well defined. Moreover, it has not been determined whether bud dormancy induced by environmental cues, such as a low red-to-far-red light ratio, shares genetic mechanisms with bud latency induced by other causes, such as apical dominance or a short-day photoperiod. Furthermore, the evolution and conservation of these GRNs throughout angiosperms is not well established. We have reanalyzed public transcriptomic datasets that compare quiescent and active axillary buds of Arabidopsis, with datasets of axillary buds of the woody species Vitis vinifera (grapevine) and apical buds of Populus tremula x Populus alba (poplar) during the bud growth-to-dormancy transition. Our aim was to identify potentially common GRNs induced during the process that leads to bud para-, eco- and endodormancy. In Arabidopsis buds that are entering eco- or paradormancy, we have identified four induced interrelated GRNs that correspond to a carbon (C) starvation syndrome, typical of tissues undergoing low C supply. This response is also detectable in poplar and grapevine buds before and during the transition to dormancy. In all eukaryotes, C-limiting conditions are coupled to growth arrest and latency like that observed in dormant axillary buds. Bud dormancy might thus be partly a consequence of the underlying C starvation syndrome triggered by environmental and endogenous cues that anticipate or signal conditions unfavorable for sustained shoot growth.

“…Recent studies have shown that expression of CBL1 and CIPK14 was induced by glucose treatment, and knockout mutations in CIPK14 and CBL1 resulted in hypersensitivity to glucose treatment (Li et al, 2013;Yan et al, 2014). Moreover, CIPK14 was reported to interact with CBL2, CBL3, and CBL9 (Yan et al, 2014). According to our RNA-seq data, the CIPK20 and 3 putative Ca2+ binding proteins were regulated by glucose, indicating that CBLs and CIPKs are involved in plant glucose signaling.…”

ABSTRACT. Sugars acting as fuel energy or as signaling molecules play important roles in plant growth and development. Although sugars associated with early seedling development have been analyzed in detail, few studies have examined the effect of sugar on genome-wide gene transcription. To analyze the role of glucose on the genomic level, we examined the response of seedlings to 5% glucose using RNA-seq technology. High concentrations of glucose significately altered the expression of 863 genes, with 558 upregulated and 305 downregulated genes by more than 2-fold. A large number of genes affected by glucose were involved in metabolic processes and signaling. Transcript levels for many kinases and calcium signals were downregulated. Most transcription factors identified were also involved in glucose signaling. Moreover, many genes related to the auxin, gibberellin, and abscisic acid responses were upregulated or downregulated. Additionally, the K + , Ca 2+ , SO 3 -, NO 3 -, PO 4 3-, amino acid, and sugar transporters were also upregulated or downregulated. These results provide a basic 4784-4801 (2015) understanding of the glucose-mediated molecular mechanisms in the regulation of early seedling development.
