Some deleterious effects of drought, soil salinity and other abiotic stresses are mediated by the generation of oxidative stress through an increase in reactive oxygen species (ROS) that damage cellular membranes...
Conservation of orchid species (Orchidaceae) can be challenging, particularly for a small Diuris group of four species from southeastern Australia. To determine best conservation practices for the four species, Ahrens...
Evergreen conifers face a unique challenge during winter: it is too cold for photosynthesis, but their leaves still absorb light energy. This can be dangerous to leaf tissues if the absorbed light energy is not...
Pollinators are often given precedence as the primary drivers behind the evolution of floral traits. Yet a growing body of research is beginning to stress the importance of other significant selective agents...
We study plant roots by observing their developmental stages, physiological conditions and their cell biology. The advent of fluorescent proteins and the power of confocal microscopy have enabled us to track the...
Although the underlying phylogeny determines the qualitative wood structure, climate has a significant influence on the functional wood anatomy of Acacia. Warwick et al. use microscopy to investigate the structural...
Invasive herbivores can dramatically impact the nitrogen economy of native hosts. In eastern forests of the United States, the foundational conifer eastern hemlock (Tsuga canadensis) is under threat of extirpation by...
Botanists have long been fascinated by the extraordinary diversity in flowering plant reproductive patterns and have sought to understand the ecological processes and genetic mechanisms influencing plant mating. Over...
Oak decline is still a characterised by symptoms of canopy transparency, bark cracks and reduced root biomass. Decline causes losses of fine root length, and a moderate recovery can be achieved by thinning, allowing...
Global warming accelerates plant water use, increasing plant susceptibility to drought death. From this, it can be hypothesised that higher CO2 concentrations slow plant water use, and should offset the warming effects...
Repeated losses of mature corolla bilateral symmetry are not uncommon. Zhong et al. focus on repeated and diverse losses of bilateral symmetry testing whether similar or distinct developmental genetic mechanisms...
