Plastic and adaptive gene expression patterns associated with temperature stress in Arabidopsis thaliana
Article Abstract:
The effects of temperature stress on gene expression in the Arabidopsis thaliana model system are examined. The results have supported the association between plasticity of gene expression and adaptive value and in comparison to non-plastic genes, genes displaying plastic expression patterns are associated with greater among-ecotype variation in expression levels, which is correlated with geographical temperature gradients.

Quantitative genetics: Small but not forgotten
Article Abstract:
Kroymann and Mitchell-Olds have used an empirical approach to examine the prevalence of small-effect Quantitative Trait Loci (QTL) present in any gene, and epistatic interactions. It cannot be necessarily concluded from their work that the genome is full of small-effect QTL as the region studied is not surely representative of the whole genome and additional regions need to be sampled before generalization.

Effects of gibberellin mutations on tolerance to apical meristem damage in Arabidopsis thaliana
Article Abstract:
The role of gibberellin hormones (GAs) in tolerance to apical meristem damage (AMD) is examined by characterizing the reaction norms of several GA-deficient and insensitive mutants of Arabidopsis thaliana. Early-flowering genotypes of A. thaliana was found to be remarkably tolerant to AMD and GA deficiency or GA insensitivity was not responsible for hindering tolerance to AMD in the genetic background.
