Analysis of ecotype Columbia glabra seedlings subjected to anoxia for 6 hours in the presence or absence of 90 uM sucrose. Exogenous sucrose enhances the tolerance of seedlings to anoxia. Results identify candidate genes that enhance the tolerance of sucrose treated seedlings to anoxia.

(Submitter supplied) Arabidopsis thaliana ecotype Columbia glabra were grown for 4 days in the dark without added sucrose. Samples were subsequently kept for 6h either [1] under aerobic conditions, [2] under anoxia in absence of sucrose or [3] under anoxia in presence of sucrose. Keywords: other

(Submitter supplied) A chemical screen was performed in search of compounds that modify plant responses to sucrose. This screen uncovered that sulfamethoxazole (SMX), a folate biosynthesis inhibitor, acted synergistically with sucrose to inhibit hypocotyl elongation, suggesting interaction between these two pathways. Transcriptome analysis was performed to identify changes in transcript abundance that may underpin crosstalk between sucrose and SMX. more...

(Submitter supplied) Anoxia induces several heat shock proteins and a heat pre-treatment can acclimatize Arabidopsis seedlings to a subsequent anoxic treatment. In this work we analyzed the response of Arabidopsis seedlings to anoxia, heat and a combined heat+anoxia stress. A significant overlapping between the anoxic and heat shock responses has been observed by whole-genome microarray analysis.

(Submitter supplied) Rice (Oryza sativa L.) seeds can germinate in complete absence of oxygen. Under anoxia, the rice coleoptile elongates, reaching a length greater than that of the aerobic one. In this series, we compare the transcriptome of rice coleoptiles grown under aerobic and anaerobic conditions. Lasanthi-Kudahettige, R, et. al. Plant Physiology (2007).

Analysis of coleoptiles of rice grown under anaerobic conditions. Rice seeds are capable of germinating in the absence of oxygen. Under anoxia, rice coleoptiles reach lengths greater than that of aerobically grown rice. Results provide insight into the control of anaerobic carbohydrate metabolism.

(Submitter supplied) rs05-05_atrazine - effect of atrazine and sucrose on arabidopsis transcriptome - Growth in the presence of sucrose was shown to confer to Arabidopsis thaliana seedlings, under conditions of in vitro culture, a very high level of tolerance to the herbicide atrazine and to other photosynthesis inhibitors (Sulmon et al., 2004). The CATMA investigation will be useful to reveal the gene networks implicated in the mechanisms of xenobiotics tolerance. more...

(Submitter supplied) Background Protein synthesis is a highly energy demanding process and is regulated according to energy availability in plant cells. Light and sugar availability affect mRNA translation but the specific roles of these factors remain unclear. In this study, sucrose was applied to Arabidopsis seedlings kept in the light or in the dark, in order to distinguish sucrose and light effects on transcription and translation. more...

(Submitter supplied) HRE1 and HRE2 are two ERF transcription factors induced by low oxygen. In this work we analyzed the effect of ectopic expression of HRE1 and HRE2 on the arabidopsis transcriptome in aerobic and hypoxic (1% O2) conditions. While HRE1 has a moderate effect on the expression of anaerobic genes under hypoxia, HRE2 does not affect them either under aerobic or hypoxic conditions.

(Submitter supplied) Light, an important environmental factor regulates most of plant physiology and development. In the photomorphogenic stage, light globally enhances translation status in de-etiolating Arabidopsis seedlings. More than 1500 genes showed increased translation but not transcription in this developmental process. This implies these mRNAs are translationally repressed in dark-grown seedlings. Through transcriptome and translatome comparisons, we revealed that p-bodies attenuate the translation of mRNAs in the etiolated seedlings. more...
