Coordination of photosynthetic traits across soil and climate gradients

Global Change Biology, Volume 29, Issue 3, Page 856-873, February 2023., 2023
Using an Australia‐wide photosynthetic trait dataset, we tested predictions from least‐cost optimality theory, which posits that plants balance nutrient use and water loss to optimize photosynthesis. We found that leaf nitrogen and rates of water loss co‐vary with one another in response to climate and to a lesser extent, soils.

Production of unique immunotoxin cancer therapeutics in algal chloroplasts

Proceedings of the National Academy of Sciences of the United States of America, 2012
The idea of targeted therapy, whereby drug or protein molecules are delivered to specific cells, is a compelling approach to treating disease. Immunotoxins are one such targeted therapeutic, consisting of an antibody domain for binding target cells and ...

Eco‐Friendly Synthesis of Selenium Nanoparticles via Sternbergia candida: Enhancing Antioxidant Defense and Mitigating Salt Stress in Pepper (Capsicum annuum L.) Plants

ChemistryOpen, EarlyView.
Sternbergia candida serves as a flexible reducing agent for the synthesis of SeNPs utilizing an economical and ecologically safe extract. Applications of selenium have demonstrated that plants cultivated in salinity preserve proper osmotic conditions and minimize cellular damage, as evidenced by photosynthetic pigments, proline, and MDA data.

Radiation‐constrained boundaries cause nonuniform responses of the carbon uptake phenology to climatic warming in the Northern Hemisphere

Global Change Biology, Volume 29, Issue 3, Page 719-730, February 2023., 2023
The constraint of temperature and radiation on vegetation productivity was estimated with the variable θ. Values of θ differ during the start and end of season (SoS and EoS), indicating that radiation constraints the trend towards longer growing seasons but differently during spring and autumn.

Chloroplasts of Arabidopsis Are the Source and a Primary Target of a Plant-Specific Programmed Cell Death Signaling Pathway[W]

The Plant Cell, 2012
Under mild light stress, plants enhance the production of singlet oxygen that acts as a signal. Singlet oxygen–mediated signaling forms an integral part of photosynthesis that translates environmental variability affecting photosynthetic electron ...

Microbiota diversity and differences in the respiratory tract of children with pneumonia

Pediatric Investigation, EarlyView.
Differences in microbial communities in the upper and lower respiratory tract in patients with pneumonia were investigated in this study by sequencing the 16S rRNA genes in pharyngeal swabs and alveolar lavage fluid. Forty‐three subjects were enrolled in the study, and one upper and one lower respiratory tract sample were collected from each subject ...

Morphodynamics of chloroplast network control light-avoidance response in the non-motile dinoflagellate Pyrocystis lunula [PDF]

arXiv
Photosynthetic algae play a significant role in oceanic carbon capture. Their performance, however, is constantly challenged by fluctuations in environmental light conditions. Here, we show that the non-motile single-celled marine dinoflagellate Pyrocystis lunula can internally contract its chloroplast network in response to light. By exposing the cell
