No sexual niche partitioning in a dioecious moss
Roughly half of the species of bryophytes have separate sexes (dioecious) and half are hermaphroditic (monoecious). This variation has major consequences for the ecology and evolution

Zinc stress and ROS and RNS metabolism of roots
Zinc (Zn) is an essential micronutrient naturally present in soils, but anthropogenic activities can lead to accumulation in the environment and resulting damage to plants. Heavy

Glutathione, ascorbate and cadmium sensitivity in arabidopsis
Cadmium (Cd) is a non-essential trace element that elicits oxidative stress. Plants respond to Cd toxicity via increasing their Cd-chelating and antioxidative capacities. They

Wound-periderm-like tissue induced by UV-B radiation
Nascimento et al. expose plants to supplemental UV-B radiation and find that it causes the formation of brown areas on the leaves, which develop into a protective tissue on the adaxial side of the leaf, but only in directly exposed regions

Mitochondrial energy-dissipation systems in plants (Review)
Plants are sessile organisms that have the ability to integrate external cues into metabolic and developmental signals. The cues initiate specific signal cascades that can enhance

250 years of hybridization between two biennial herb species without speciation
In 1759, Linnaeus convinced his followers that plants could hybridize by crossing flowers in the daisy family and producing intermediate offspring. These hybrids, between Tragopogon pratensis

Over-expression of Trxo1 and cell viability under H2O2 stress
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

Role of AOX1A in optimizing photosynthesis
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

Thinking outside the box?
How well will plants – and plant-like organisms – function with rising concentrations of levels of atmospheric CO2? And how will the increases in temperatures – associated with climate change/global warming – affect them? Given the importance of marine phytoplankton organisms to global p
