Ortiz-Espín et al. [http://dx.doi.org/10.1093/aob/mcv076] treat over-expressing PsTrxo1 tobacco (Nicotiana tabacum) BY-2 cells with H2O2 and find a significant delay in cell death compared to controls, which may in part be due to a decreased content of endogenous H2O2 in the over-expressing cells, i

Vishwakarma et al. [http://dx.doi.org/10.1093/aob/mcv122] treat wild-type and aox1a knock-out mutants of Arabidopsis thaliana with antimycin A and find that restriction of the cytochrome c oxidase (COX) pathway in the background of an impaired AOX pathway results in a substantial decrease in respira

Ozgur et al. [http://dx.doi.org/10.1093/aob/mcv072] induce the formation of reactive oxygen species (ROS) in chloroplasts, mitochondria and peroxisomes of Arabidopsis thaliana and find that relatively low concentrations of ROS are more effective for induction of the ER stress response, and that mito

Kartzinel et al. [http://dx.doi.org/10.1093/aob/mcv117] use genetic markers to determine the extent and overlap of genetically unique kudzu vines (Pueraria montana var. lobata) in multiple patches over 2 years, and find that, contrary to expectations, patches are not dominated by one or a few genets

The phylogeography, the study of the spatial and temporal history of a species, remains largely unclear for plant species in sub-tropical China. Zhang et al. [http://dx.doi.org/10.1093/aob/mcv112] use Tapiscia sinensis, an endemic tree species, as a model to study the phylogeographical history and p

Marquez-Garcia et al. study the effects of drought in leaves and nodules of soybean (Glycine max) and find that while the physiological impact is perceived throughout the shoot, stress-induced senescence occurs only in the oldest leaf ranks.
