Mitigating Salinity Stress in Pea Plants with Titanium Oxide Nanoparticles

open access: yesInternational Journal of Plant Biology
Changes in the environment have a significant impact on photosynthetic efficiency, which in turn influences plant growth and yield. Consequently, there is a greater focus on methods to enhance photosynthetic efficiency with the goal of raising plant ...

Melatonin Is Involved in Regulation of Bermudagrass Growth and Development and Response to Low K+ Stress

open access: yesFrontiers in Plant Science, 2017
Melatonin (N-acetyl-5-methoxytryptamine) plays critical roles in plant growth and development and during the response to multiple abiotic stresses. However, the roles of melatonin in plant response to K+ deficiency remain largely unknown.

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

open access: yesPest Management Science, EarlyView.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Photosynthesis-Inhibiting Activity of 1-[(2-Chlorophenyl)carbamoyl]- and 1-[(2-Nitrophenyl)carbamoyl]naphthalen-2-yl Alkylcarbamates

open access: yesMolecules, 2017
Eight 1-[(2-chlorophenyl)carbamoyl]naphthalen-2-yl alkylcarbamates and eight 1-[(2-nitrophenyl)carbamoyl]naphthalen-2-yl alkylcarbamates were tested for their activity related to the inhibition of photosynthetic electron transport (PET) in spinach ...

Fendioxypyracil, a new and systemic PPO‐inhibiting herbicide for X‐spectrum weed control

open access: yesPest Management Science, EarlyView.
This graphical abstract presents the discovery and synthesis of PPO herbicide structures with a central pyridine core, showing molecular conformations, dose–response inhibition curves for PPO1 and PPO2, and comparative weed and grass control efficacy of fendioxypyracil versus other herbicides in greenhouse and field trials.

Selenium treatment affected respiratory potential in Eruca sativa

open access: yesActa Agriculturae Slovenica, 2005
The effect of selenium on Eruca sativa Miller was studied. The flows of electrons in the photosynthetic apparatus and in the respiratory chain were measured in control plants and in plants obtained from selenium treated seeds. The potential and effective

Spectral signatures of photosynthesis II: coevolution with other stars and the atmosphere on extrasolar worlds

open access: yes, 2007
As photosynthesis on Earth produces the primary signatures of life that can be detected astronomically at the global scale, a strong focus of the search for extrasolar life will be photosynthesis, particularly photosynthesis that has evolved with a ...
