Project description:We systematically identified long noncoding natural antisense transcripts (lncNATs), defined as lncRNAs transcribed from the opposite DNA strand of coding or noncoding genes. We identified in total 37,238 sense-antisense transcript pairs and found 70% mRNAs are associated with antisense transcripts in Arabidopsis. To investigate the role of NATs in response to white light treatment, we designed an Agilent custom array, ATH NAT array, and analyzed WT seedlings grown in the dark (0h) and seedlings undergoing de-etiolation in continuous white light for 1h and 6h. To obtain information on organ-specific transcriptome profiles, we further dissected seedlings into cotyledons, hypocotyls and roots.

Project description:Driven by cell elongation, hypocotyl growth is tightly controlled by light and responds to both external stimuli and endogenous hormonal pathways. Hypocotyls are responsive to the stress signalling hormone abscisic acid (ABA), which effectively inhibits cell elongation. However, how this regulation is connected to light signalling has been a subject of limited studies. Here, we show that, contrary to light-grown seedlings, hypocotyl elongation of dark-grown seedlings is ABA-insensitive. In the dark, hypocotyl sensitivity to ABA is restored in the constitutive photomorphogenic pifq and cop1-4 mutants, suggesting that an active light signalling pathway is necessary for hypocotyl responsiveness to ABA. Surprisingly, etiolated hypocotyls retain an intact ABA signalling pathway, as could be detected by the induction of ABI1 and RD29B transcripts in response to exogenous ABA, suggesting that inhibition of hypocotyl elongation occurs through a divergent path that can be inhibited by PIFs. Here, using RNA-seq analysis we identified a number of ABA differentially expressed genes (DEGs) that correlate with ABA inhibition of hypocotyl elongation. Among these DEGs a number of SMALL AUXIN-UP RNA (SAUR) genes that are known to directly repress D-CLADE TYPE 2C PROTEIN PHOSPHATASES (PP2C.D) were found. The abrogation of PP2CD.D2-SAUR interaction in the pp2c.d2/PP2C.D2M331K -GFP line, restored ABA sensitivity in the dark, suggesting that SAUR proteins, upregulated by PIFs, are sufficient to render hypocotyls insensitive to ABA. This hypocotyl-specific mechanism enables to promote growth towards the light at all costs, overriding ABA inhibition of cell elongation, to ensure subsequent seedling establishment and survival.

Project description:The associated files are mass spec data from 4 separate mixed-bed ion exchange column separations of Arabidopsis thaliana Col-0 seedling native extract. Two fractionations used extract from seedlings grown in light and two fractionations used extract from etiolated seedlings (grown in the dark). All fractions were processed similarly for LC-MS/MS but one light-grown fractionation was analyzed on a different mass spectrometer than the other three sets of ion exchange fractions.

Project description:Arabidopsis, when grown under short day conditions (16 hours dark, 8 hours light, 22oC) develop extensive secondary thickened hypocotyls with both a vascular and cork cambium (Chaffey et al, 2002, Phys. Plant., 114:594-600). It has been found that once secondary xylem development is completed within the Arabidopsis hypocotyls, it closely resembles the structure of the wood of angiosperm trees (Chaffey et al, 2002, Phys. Plant., 114:594-600). We can utilise this model Arabidopsis tree to identify genes that are important for secondary cell wall formation in xylem cells and therefore important for wood development. Columbia plants were grown for 3 months under short day conditions and secondary thickened hypocotyls were snap-frozen in liquid nitrogen. RNA was isolated from these hypocotyls and submitted to NASC for probing against the ATH1-121501 full GeneChip. Keywords: growth_condition_design
