Plant pathologists like all other scientists are imparted scientific knowledge and technical expertise, building the educational side of their career. Beckerman and Schneider emphasize the pressing needs of teaching ‘soft skills’ scientists need in order to improve their leadership and professional…

It has been stated that adaptive evolution occurs in plant populations with respect to various complex traits. Olofsson et al. validated the hypothesis that different components of a complex trait can evolve in isolation and later be combined by gene flow by using C4 photosynthesis as a study system.…

Crassulacean acid metabolism (CAM) is a specialized form of photosynthesis that greatly increases water-use efficiency by taking up CO2 through stomata that are open at night (when evapotranspiration is low). Engineering plants that can switch to CAM during periods of drought is a key goal towards…

Traditionally, the production of hybrid maize seed involved the removal of male flowers to prevent self-fertilization of the female flowers. Rice produces bisexual flowers, so mechanical emasculation is not as amenable. Therefore, hybrid rice production requires that the female parent be genetically…

Although it is widely accepted that high humidity has a strong influence on plant diseases of the phyllosphere (the above-ground portions of the plant), the molecular basis is not understood.  Xin et al. report that an important step in bacterial infection of the phyllosphere is a pathogen-driven…

When villagers see the marauding hordes approaching, they secure their food sources. Similarly, when the cell-surface FLS2 receptor detects a bacterial pathogen, it (through its co-receptor BAK1) phosphorylates and stimulates the activity of a cell-surface sugar transporter (STP13), leading to the…

The wavelenghts of light perceived by a plant are information-rich, and plants integrate information from photoreceptors tuned to different wavelenghts to optimize their growth and development. Because plants absorb red light but not far-red light, a low ratio of red to far-red light indicates vegetative…

A seedling in the dark produces ethylene, which in a dicot such as Arabidopsis leads to apical hook formation that protects the cotyledons from damage as the seedling pushes through the soil. The emergence of the seedling into the soil causes a rapid transition to photomorphogenesis and a suppression…
