Useful or merely convenient? On the issue of a suitability of enzymatic antioxidant activity as a proxy for abiotic stress tolerance.

During their lifespan, plants are often exposed to a broad range of stresses that change their redox balance and lead to accumulation of reactive oxygen species (ROS). The traditional view is that this comes with negative consequences to cells structural integrity and metabolism and, to prevent this, plants evolved a complex and well-coordinated antioxidant defence system that relies on the operation of a range of enzymatic and non-enzymatic antioxidants (AO). Due to the simplicity of measuring their activity, and in the light of the persistent dogma that stress-induced ROS accumulation is detrimental for plants, it is not surprising that enzymatic AO have often been advocated as suitable proxies for stress tolerance, as well as potential targets for improving tolerance traits.

Genome-wide association study reveals quantitative trait loci for waterlogging-triggered adventitious roots and aerenchyma formation in common wheat.

Waterlogging severely affects wheat growth and development. Limited availability of oxygen in the root zone negatively affects the metabolism of plants. The formation of adventitious roots (ARs) and root cortical aerenchyma (RCA) are the most important adaptive trait contributing to plants' ability to survive in waterlogged soil conditions.

Transcriptome Classification Reveals Molecular Subgroups in Idiopathic Pulmonary Fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a disease of progressive lung fibrosis with a high mortality rate. This study aimed to uncover the underlying molecular features for different types of IPF. IPF microarray datasets were retrieved from GEO databases.
