Arabidopsis Gene 1.1 ST Array (aragene11st)
Description
ALTERED MERISTEM PROGRAM1 (AMP1) is a member of the M28 family of carboxypeptidases with a pivotal role in plant development and stress adaptation. Its most prominent mutant defect is a unique hypertrophic shoot phenotype combining a strongly increased organ formation rate with enhanced meristem size and the formation of ectopic meristem poles. However, so far the role of AMP1 in shoot development could not be assigned to a specific molecular pathway nor is its biochemical function resolved. We used a chemical genetic approach to identify the drug hyperphyllin (HP), which specifically mimics the shoot defects of amp1, including plastochron reduction and enlargement and multiplication of the shoot meristem. To further assess whether hyperphyllin acts in an AMP1-dependent manner we compared the transcriptonal responses of hyperphyllin-treated wild-type and amp1 mutant seedlings.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Arabidopsis seedlings, of both wild-type and an ARF7/ARF19 double knockout mutant, were grown to 7 days post-germination. The roots were then dissected into 5 developmental zones, the meristem, early elongation zone, late elongation zone, mature root and lateral root zone. The sections then underwent transcriptional profiling to identify processes and regulatory events specific and in common to the zones.

Description
Different progesterone levels and timing of exposure results in different endometrial gene expression and implantation potential. Sufficient progesterone level is important to induce endometrial receptivity and endometrial expressed the most receptive stage after exposure to progesterone for 7 days based on decidualisation marker expression.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
In Arabidopsis, lateral roots (LRs) originate from pericycle cells located adjacent to vascular tissues, deep within the primary root. Consequently, new LR organs have to emerge through several overlying tissues. Eight stages of LR primordium development have been defined, with stage I representing a single layer of primordium cells generated by the first round of asymmetric divisions and stage VIII defining primordia that have fully emerged through the outer cell layers. To identify novel genes involved in LR development, we generated a transcriptomic time course dataset encompassing each LR developmental stage from pre-initiation to post-emergence.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
Commercial brewing yeast strains are exposed to a number of potential stresses including oxidative stress. The aim of this investigation was to measure the physiological and transcriptional changes of yeast cells during full-scale industrial brewing processes with a view to determining the environmental factors influencing the cells oxidative stress response. Cellular antioxidant levels were monitored throughout an industrial propagation and fermentation and microarray analysis was employed to determine transcriptional changes in antioxidant-encoding and other stress response genes. The greatest increase in cellular antioxidants and transcription of antioxidant-encoding genes occurred as the rapidly fermentable sugars glucose and fructose were depleted from the growth medium (wort) and the cell population entered the stationary phase. The data suggest that, contrary to expectation, the oxidative stress response is not influenced by changes in the dissolved oxygen concentration of wort but is initiated as part of a general stress response to growth-limiting conditions, even in the absence of oxygen. A mechanism is proposed to explain the changes in antioxidant response observed in yeast during anaerobic fermentation. The results suggest that the yeast cell does not experience oxidative stress, per se, during industrial brewery handling. This information may be taken into consideration when setting parameters for industrial brewery fermentation.
