Gene network downstream plant stress response modulated by peroxisomal H2O2

(Submitter supplied) Study of the effect of cadmium on KO and overexpressor mutants of glycolate oxidase-GOX2, which is one of the main sources of H202 from peroxisomes. Reactive oxygen species (ROS) act as secondary messengers that can be sensed by specific redox sensitive proteins responsible for the activation of signal transduction culminating in altered gene expression. ROS, which are involved in different activities, elicit a wide range of protein modifications, which might elicit different gene expressions. more...

OBP4 modifies root growth, cell elongation and callus formation

(Submitter supplied) Investigation of whole genome gene expression level changes in Arabidopsis roots by overexpressing OBP4 transcription factor under teh control of an estradiol inducible promoter This work analyzes the effect of overexpression the transcription factor OBP4 in gene transcription. Details of how ectopic expression affects root development and callus formation are described in Rammirez-Parra et al. (submitted)

Root development and responses are alerted by light

(Submitter supplied) Investigation of whole genome gene expression level changes in Arabidopsis roots by the effect of light. Plant growth is sustained by a continuous cell division in meristems followed by cell differentiation and elongation. We have found that in Arabidopsis thaliana roots, flavonols play a key role in regulating the transition from cell division to differentiation. Using an engineered device to grow roots in darkness, but shoot in light cycle, coupled with transcriptomic and metabolomics analysis, we deciphered that flavonols accumulation regulates proliferation-promoting levels of auxin-PLETHORA and superoxide anion (O2-). more...

IBMCP JLeon lab NO-exposed (15, 30 and 60 min after pulse of 300 ppm NO during 5 min) wt Col-0 versus untreated wt Col -0

(Submitter supplied) Compared analysis of the transcriptomes of 12-day old seedlings from wild type Col-0 treated with NO for 15, 30 and 60 min vs untreated control seedlings. Samples were harvested 12 h after dawn of day 12 after sowing and seedlings were grown under long days (16 h light / 8 h darkness) photoperiodic conditions.

Gene expression analysis of jmj30 jmj32 mutant grown at 29°C under long day conditions

(Submitter supplied) Analysis of loss-of-function mutants of JUMONJI30 (JMJ30) and JMJ32 in Arabidopsis thaliana (Col). JMJ30 and JMJ32 encode the histone demethylases that contain the catalytic JmjC domain. The trimethylation of Histone H3 lysine 27 (H3K27me3) plays a key role in gene repression and developmental regulation. It is actively and dynamically deposited and removed in plants. However, while the H3K27 methyltransferases had been extensively studied, findings on the H3K27 demethylase were few. more...

Transcript data affected by constitutive expression of VvMYBPAR in Arabidopsis

(Submitter supplied) Constitutive expression of VvMYBPAR in Arabidopsis was found to accumulate proanthocyanidins when the plants were grown on sucrose-supplemented media to induce anthocyanins. To identify the putative targets of VvMYBPAR, the transcriptome analysis of the transgenic lines which highly express VvMYBPAR was carried out using NimbleGen microarray.

WRKY6 Transcription Factor Restricts Arsenate Uptake and Transposon Activation in Arabidopsis

(Submitter supplied) Stress constantly challenges plant adaptation to the environment. Of all stress types, arsenic was a major threat during the early evolution of plants. The most prevalent chemical form of arsenic is arsenate, whose similarity to phosphate renders it easily incorporated into cells via the phosphate transporters. Here we found that arsenate stress provokes a notable transposon burst in plants, in coordination with arsenate/phosphate transporter repression, which immediately restricts arsenate uptake. more...
