Interactions between the respiratory chain and protein import complexes have been previously reported in Saccharomyces cerevisiae, but the biological significance of such interactions remains unknown. Characterization of two mitochondrial preprotein and amino acid transport proteins from Arabidopsis thaliana, NADH dehydrogenase B14.7 like (B14.7 [encoded by At2g42210]) and Translocase of the inner membrane subunit 23-2 (Tim23-2 [encoded by At1g72750]), revealed both proteins are present in respi ...[more]

LETM2 is required for translation of mitochondrial encoded transcripts and is controlled by maternal epigenetic pathways in Arabidopsis thaliana

Project description:Arabidopsis ATH1 Genome Arrays were used to analyse changes in transcript abundance between Col-0 (wild-type) Arabidopsis seedlings and either single T-DNA insertional KO mutants of LETM1 (At3g59820)(T-DNA lines; SALK_067558C (letm1-1) and SALK_058471 (letm1-2)) or LETM2 (At1g65540) (T-DNA line; SALK_068877 (letm2-1)). Additionally, letm1 and letm2 knock out Arabidopsis lines were crossed to generate double mutants, however a double knock-out of these two genes results in an embryo lethal phenotype. Hemizygous plants were generated that were homozygous knock out for LETM1 and heterozygous knock out for LETM2, and visa versa, termed (letm1(-/-)LETM2(+/-) and (LETM1(+/-)letm2(-/-) respectively. Note that (letm1(-/-)LETM2(+/-) displays a mild developmental defective phenotype in the first 10-14 days of growth, while (LETM1(+/-)letm2(-/-) shows no phenotype. Microarray analysis was carried out on all three single homozygous knock out lines, and also on both combinations of the hemizygous mutation between the two genes, and compared with a wild-type Col-0 control to gain insight into global transcript abundance changes in these mutant lines. Arrays were performed in triplicate for each genotype, from RNA isolated from 3 independent pools of 5-10 Arabidopsis seedlings at 10 days old.

Transcription profiling of SALK_084897 or SAIL_303_D08 Arabidopsis plants grown under normal conditions or with moderate light and drough treatment applied

Project description:4 week old Arabidopsis plants, of ecotype Columbia, SALK_084897 or SAIL_303_D08 were either grown under normal conditions or grown under normal conditions for before having a moderate light and drought treatment applied. Light and drought treatment was applied by withholding water for 5 days prior to transfer to 300 uE m-2 s-1 light conditions. Samples were collected after 3 days of treatment or for the same age plants grown under normal conditions.

Transcription profiling of Arabidopsis dehydration on soil

Project description:Arabidopsis plants were grown in plastic pots filled with peat moss for 3 weeks (principal growth stage 1.07-1.08) under a 16 h light/8 h dark regimen (40 ± 10 ?mol photons/m2/s) at 22 C.Dehydration treatment: The 3-week-old plants were grown for 2 or 3 days without watering. To obtain accurate results, we carefully raised single plants in Petri dishes, each containing an equal amount of soil. Soil moisture contents were calculated from soil dry weight. Untreated; the soil moisture content was 84.3%. Under dehydration, on the second day, the soil moisture content was 51.1%. Under dehydration, on the third day, the moisture content was 11.6%.

Transcription profiling of AtHsp70-14 and AtHsp70-15 deficient Arabidopsis thaliana plants

Project description:AtHsp70-14 and -15 (At1g79930 and At1g79920) are two closely related isoforms of the Hsp110/SSE subfamily of the HSP70 chaperones in Arabidopsis thaliana. By analysing T-DNA insertion and amiRNA-AtHsp70-14/15 lines, we could demonstrate an essential function of AtHsp70-15 for plant growth. AtHsp70-15 deficient plants are reduced in size and stomata opening is impaired which results in accelerated wilting of detached leaves. Hsp70-15 deficient plants are also more tolerant to TuMV infection but more sensitive to heat treatment. Therefore comparative transcriptome analysis of amiRNA-AtHsp70-14/15, hsp70-14 knockout, hsp70-15 knockout and wild type plants was performed with leaf samples of 6 week old plants grown under ambient conditions. The analysis of differentially regulated genes compared to the wild type Col-0 plants exhibited a constitutive heat stress response / cytosolic protein response of Hsp70-15 deficient plants.

Transcription profiling of Arabidopsis response to cold on soil

Project description:Arabidopsis plants were grown in plastic pots filled with peat moss for 3 weeks (principal growth stage 1.07-1.08) under a 16 h light/8 h dark regimen (40 ± 10 ?mol photons/m2/s) at 22 C. The light intensity was the same at 22 C and at 4 C. Plants were harvested 2 h later after lights were turned on. Cold treatment: The 3-week-old plants were transferred from 22 C to 4 C and were grown for 1 or 4 days.
