Photosynthetic responses of sun- and shade-grown barley leaves to high light: is the lower PSII connectivity in shade leaves associated with protection against excess of light? [PDF]
Photosynthesis Research, 2014 In this study, we have compared photosynthetic performance of barley leaves (Hordeum vulgare L.) grown under sun and shade light regimes during their entire growth period, under field conditions. Analyses were based on measurements of both slow and fast chlorophyll (Chl) a fluorescence kinetics, gas exchange, pigment composition; and of light incident ...

Mechanism Underlying the Shading-Induced Chlorophyll Accumulation in Tea Leaves [PDF]
Frontiers in Plant Science, 2021 Besides aroma and taste, the color of dry tea leaves, tea infusion, and infused tea leaves is also an important index for tea quality. Shading can significantly increase the chlorophyll content of tea leaves, leading to enhanced tea leaf coloration. However, the underlying regulatory mechanism remains unclear.

More Manganese Accumulates in Maple Sun Leaves than in Shade Leaves [PDF]
Plant Physiology, 1989 Nuclear magnetic resonance and neutron activation analysis were used to measure manganese concentrations in leaves of Acer platanoides. Mn was found to accumulate in both the vacuoles and the chloroplasts, with more Mn (per unit area) in sun leaves than in shade leaves. No Mn was lost at senescence.

Transcriptome response of cassava leaves under natural shade [PDF]
Scientific Reports, 2016 AbstractCassava is an important staple crop in tropical and sub-tropical areas. As a common farming practice, cassava is usually cultivated intercropping with other crops and subjected to various degrees of shading, which causes reduced productivity. Herein, a comparative transcriptomic analysis was performed on a series of developmental cassava leaves

Mechanism underlying the carotenoid accumulation in shaded tea leaves
Food Chemistry: X, 2022 Carotenoids contribute to tea leaf coloration and are the precursors of important aromatic compounds. Shading can promote the accumulation of carotenoids in tea leaves, but the underlying mechanism remains unknown. In the study, we analyzed the content and composition of carotenoids, and transcript levels and functions of related genes in carotenoid ...

Recovery kinetics of winter stressed conifers: The effects of growth light environment, extent of the season, and species. [PDF]
, 2010 Evergreens undergo a dramatic reduction in their maximal photochemical efficiency (measured as Fv/Fm) during winter, which is largely due to increases in a sustained form of thermal energy dissipation.

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.
