Take a Deep BReath: Manipulating brassinosteroid homeostasis helps cereals adapt to environmental stress.
Plant Physiol

Global climate change leads to the increased occurrence of environmental stress (including drought and heat stress) during the vegetative and reproductive stages of cereal crop development. Thus, more attention should be given to developing new cereal cultivars with improved tolerance to environmental stress. However, during the development of new stress-tolerant cereal cultivars, the balance between improved stress responses (which occur at the expense of growth) and plant yield needs to be maintained.

Central to the success of this mission are designated institutional officials (DIOs), who usually serve as chief GME officers within the ACGME-accredited sponsoring institutions (SIs). Despite the critical role of DIOs, the qualifications, level of administrative support, and responsibilities of DIOs are not defined and vary significantly among SIs.

Copper(II) oxide nanoparticles (CuO NPs) are used in different industries and agriculture, thus leading to their release to the environment, which raises concerns about their ecotoxicity and biosafety. The main toxicity mechanism of nanometals is oxidative stress as a result of the formation of reactive oxygen species caused by metal ions released from nanoparticles. Bacterial biofilms are more resistant to physical and chemical factors than are planktonic cells due to the extracellular polymeric matrix (EPM), which performs a protective function.

Forest Tree Breeding Center, Forestry and Forest Products Research Institute, Forest Research and Management Organization, Hitachi, Ibaraki 319-1301, Japan.
The selection of plant genotypes characterized by wellness and stable growth under drought-stress conditions amid ongoing climate change is an important challenge in forest tree breeding. The introduction of molecular markers will enable efficient selection of breeding materials that are resistant to drought stress in forest trees as well as in crop species. Japanese cedar, Cryptomeria japonica, the most dominant forest species in Japan, grows well on mesic sites and is characterized by intraspecific variation in its drought-stress response.

PLoS Comput Biol

Biorobotics Laboratory, EPFL, Lausanne, Switzerland.
Humans can perform movements in various physical environments and positions (corresponding to different experienced gravity), requiring the interaction of the musculoskeletal system, the neural system and the external environment. The neural system is itself comprised of several interactive components, from the brain mainly conducting motor planning, to the spinal cord (SC) implementing its own motor control centres through sensory reflexes. Nevertheless, it remains unclear whether similar movements in various environmental dynamics necessitate adapting modulation at the brain level, correcting modulation at the spinal level, or both.
