Transpiration of Sun Leaves and Shade Leaves of Olea Europaea and Other Broad-Leaved Evergreens [PDF]

Botanical Gazette, 1904
(WITH ELEVEN FIGURES) THE structural differences between sun leaves and shade leaves of several species have been described in a classical memoir by E. STAHL.' FR. JoHow has given an excellent summary of the adaptations of foliage leaves with reference to transpiration.2 LEON DUFOUR has investigated many of the differences in the vegetative and the ...

Sun leaves up-regulate the photorespiratory pathway to maintain a high rate of CO2 assimilation in tobacco

Frontiers in Plant Science, 2014
The greater rate of CO2 assimilation in sun-grown tobacco leaves leads to lower intercellular and chloroplast CO2 concentrations and, thus, a higher rate of oxygenation of ribulose-1,5-bisphosphate (RuBP) than in shade-grown leaves.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

From Chloroplast Biogenesis to Chlorophyll Accumulation: The Interplay of Light and Hormones on Gene Expression in Camellia sinensis cv. Shuchazao Leaves

Frontiers in Plant Science, 2020
Chloroplast development and chlorophyll metabolism have been well described in model plants but not in perennial woody crops. Of particular interest is the interplay between light and hormones under shade conditions.

Effects of different shade treatments on the biosynthesis of main phytohormones in the leaves of tea plants

浙江大学学报. 农业与生命科学版, 2023
Shade net covering is a conventional agronomic practice, which has been widely applied in the production of matcha. The present study used different shade treatments (black, red, blue, and yellow shade net treatments) to alter the light conditions ...
