Journal of the American Society for Horticultural Science, 2023 Snap beans are cultivars of common bean (Phaseolus vulgaris) that are cultivated for their fleshy immature pods that exhibit a wide diversity of pod shapes and sizes. The genetic basis of the snap bean pod shape is complex and involves the interaction of

Photosynthesis on Exoplanets and Exomoons from Reflected Light [PDF]
International Journal of Astrobiology 19 (2020) 210-219, 2019 Photosynthesis offers a convenient means of sustaining biospheres. We quantify the constraints for photosynthesis to be functional on the permanent nightside of tidally locked rocky exoplanets via reflected light from their exomoons. We show that the exomoons must be at least half the size of Earth's moon in order for conventional oxygenic ...

Photosynthesis re-wired on the pico-second timescale [PDF]
, 2022 Photosystems II and I (PSII and PSI) are the reaction centre complexes that drive the light reactions of photosynthesis. PSII performs light-driven water oxidation (quantum efficiencies and catalysis rates of up to 80% and 1000 $e^{-}\text{s}^{-1}$, respectively) and PSI further photo-energises the harvested electrons (quantum efficiencies of ~100 ...

Evolutionary temperature compensation of carbon fixation in marine phytoplankton [PDF]
, 2020 The efficiency of carbon sequestration by the biological pump could decline in the coming decades because respiration tends to increase more with temperature than photosynthesis.

Frontiers in Plant Science, 2016 Amine fungicides are widely used as crop protectants. Their success is believed to be related to their ability to inhibit postlanosterol sterol biosynthesis in fungi, in particular sterol-Δ8,Δ7-isomerases and sterol-Δ14-reductases, with a concomitant ...

Ultrafast spectroscopy reveals singlet fission, ionization and excimer formation in perylene film
Scientific Reports, 2021 Singlet exciton fission (SF) is a spin-allowed process whereby two triplet excitons are created from one singlet exciton. This phenomenon can offset UV photon energy losses and enhance the overall efficiency in photovoltaic devices.

Palisade cell shape affects the light-induced chloroplast movements and leaf photosynthesis [PDF]
, 2018 Leaf photosynthesis is regulated by multiple factors that help the plant to adapt to fluctuating light conditions. Leaves of sun-light-grown plants are thicker and contain more columnar palisade cells than those of shade-grown plants.

Understanding plant responses to drought: how important is woody tissue photosynthesis? [PDF]
, 2013 Within trees, it is known that a part of the respired CO2 is assimilated in chlorophyll-containing stem and branch tissues. However, the role of this woody tissue photosynthesis in tree functioning remains unclear, in particular under drought stress ...
