Expression data from 7-day-old dark-grown wild-type and dez mutant seedlings from control (1 µM) and high-Zn (100 µM) media

ABSTRACT: The transition between growth in the dark (skotomorphogenesis) and growth in the light (photomorphogenesis) is one of the most critical in plant development. Here the newly identified mutant dez is photomorphogenic in the dark and is strongly enhanced in high Zn. dez displays a shortened hypocotyl, expanded cotyledons, an elongated root and differentiated plastids in the dark contrast to wild-type seedlings that are typically skotomorphogenic, with a long hypocotyl and unexpanded cotyledons protected by an apical hook, and undifferentiated etioplasts We used microarrays to identify transcripts regulated in dez in high-Zn relative to wild-type in high-Zn, and dez in high-Zn relative to dez in control conditions.

Proteome Analysis of rapeseed Cotyledons to Light

Project description:Among multiple factors, light plays a decisive role in the switch from heterotrophic to autotrophic growth. Under dark condition, the rapeseed hypocotyl extended quickly with an apical hook, yellow and folded cotyledon, and the glyoxysome assembling. Whereas under light, the hypocotyl extended slowly, the cotyledon unfolded and turned green. In this study, we performed proteome profiling analyses to show the differential molecular responses of Brassica napus cotyledons to light and dark and reveal metabolic adaptations in postgerminative seedling establishment. In both light and dark-grown conditions.

Ethylene-independent Promotion of Photomorphogenesis by Cytokinin Requires a Functional Cytokinin and Light Signaling Pathway.

Project description:The transition of skotomorphogenesis to photomorphogenesis is induced by the perception of light and is characterized by the inhibition of hypocotyl elongation and opening of cotyledons. Although it is known that the plant hormone cytokinin, when applied in high concentrations, inhibits hypocotyl elongation in the dark-grown Arabidopsis plants, it is unclear to what extent this response is the result of cytokinin alone or cytokinin-induced ethylene production. We show that treatment of etiolated seedlings in presence of ethylene inhibitors (eg. AgNO3) or treatment of the ethylene-resistant mutant ein2, resulted in a significant inhibition of hypocotyl elongation. This indicates that cytokinin induced de-etiolation is largely independent of ethylene and suggests a close connection between the cytokinin two component system and the light singalling networks. We show that this cytokinin signal is mainly mediated through the cytokinin receptor ARIBIDOPSIS HISTIDIN KINASE 3 (AHK3) and the ARABIDOPSIS RESPONSE REGULATORS 1 (ARR1) in combination with ARR12. Interestingly, mutation of COP1, DET1 and CIN4/COP10 renders plants insensitive to cytokinin and these factors are indispensable for the transcriptional response during cytokinin induced de-etiolation which indicates that a functional light signaling pathway is essential for this cytokinin response. In addition, the cytokinin effect on hypocotyl elongation is highly dependent on the ambient light conditions where higher light intensities causes a switch in the response to CK from an inhibitor to a promoter of hypocotyl elongation.

Genome-wide identification of PIF1-binding sites and direct-target genes of PIF1 transcriptional regulation in skotomorphogenesis

Project description:Dark-grown seedlings exhibit skotomorphogenic development. Genetic and molecular evidence indicates that a quartet of Arabidopsis Phytochrome (phy)-Interacting bHLH Factors (PIF1, 3, 4 and 5) are critically necessary to maintaining this developmental state, and that light activation of phy induces a switch to photomorphogenic development by inducing rapid degradation of the PIFs. Here, using combined ChIP-seq and RNA-seq analyses, we have identified genes that are direct targets of PIF1 transcriptional regulation, and we provide evidence that the quartet collectively regulate these genes by shared, direct binding to the target promoters in promoting skotomorphogenesis.

Interaction between gibberellins and brassinosteroids during etiolated growth in Arabidopsis.

Project description:The proper transition between the skotomorphogenic and photomorphogenic developmental programs is key for seedling survival and it is therefore tightly regulated. Besides light, which is the major cue that triggers this transition, several hormone pathways participate in this control, mainly antagonizing the light effect. Two of these hormones are gibberellins (GA) and brassinosteroids (BR). Both hormones promote the skotomorphogenesis and prevent photomorphogenesis, as evidenced by the partially de-etiolated phenotype caused by GA or BR deficiency, or by a blockage in the respective signaling pathways. We have previously shown that BR mediate GA activity in the control of this transition. For instance, treatment of dark-grown, GA-deficient seedlings with BRs was able to partially restore morphological phenotypes such as hypocotyl growth, and importantly to restore completely the molecular phenotype of CAB2 and RbcS gene expression. On the contrary, GA-treatment did not alter the same phenotypes in the BR deficient det2 mutant. Thus, the aim of this study was to investigate to what extent BRs mediate GA activity in dark-grown seedlings, and for that purpose we have the examined global changes in gene expression caused by treatment with GA and BRs in BR- and GA-deficient seedlings, respectively.
