“…A commonly cited adaptive function of epicuticular wax crystals is protection from harmful radiation by increasing UV reflectance ( Reicosky and Hanover, 1978 ; Mauseth, 1988 ; Robinson and Osmond, 1994 ; Grant et al , 2003 ). Bukhanov et al (2019) reported UV-induced fluorescence in the epicuticular wax crystal layer of wheat ( Triticum sp.). This could provide a mechanism to shift harmful UV radiation into the visible spectrum, thereby increasing light availability for photosynthesis.…”

Water shedding from leaves is a complex process depending on multiple leaf traits interacting with rain, wind and air humidity, and with the entire plant and surrounding vegetation. Here, we synthesise the current knowledge of the physics of water shedding with implications for plant physiology and ecology. We argue that the drop retention angle is a more meaningful parameter to characterise the water shedding capacity of leaves than the commonly measured static contact angle. The understanding of the mechanics of water shedding is largely derived from laboratory experiments on artificial rather than natural surfaces, often on individual aspects such as surface wettability or drop impacts. In contrast, field studies attempting to identify the adaptive value of leaf traits linked to water shedding are largely correlative in nature, with inconclusive results. We make a strong case for taking the hypothesis-driven experimental approach of biomechanical lab studies into a real-world field setting to gain a comprehensive understanding of leaf water shedding in a whole-plant ecological and evolutionary context.

“…The formation of plant pigments, their effect on color, and efficiency of photosynthesis have been studied for a long period of time [ 1 , 2 , 3 ]. Nevertheless, the importance of structural coloration has only recently begun to be taken into consideration [ 4 , 5 , 6 , 7 , 8 ], thanks to new methods that use high resolution to examine the structure [ 4 ]. Structural coloration is thought of as resonant reflection or transmission that emerges due to the ordering of objects.…”

The features of light propagation in plant leaves depend on the long-period ordering in chloroplasts and the spectral characteristics of pigments. This work demonstrates a method of determining the hidden ordered structure. Transmission spectra have been determined using transfer matrix method. A band gap was found in the visible spectral range. The effective refractive index and dispersion in the absorption spectrum area of chlorophyll were taken into account to show that the density of photon states increases, while the spectrum shifts towards the wavelength range of effective photosynthesis.

It is shown that the features of light propagation in plant leaves depend on the long-range ordering in chloroplasts and spectral characteristics of pigments. It has been established that, with regard of the dispersion of the chlorophyll absorption spectrum, the photonic density of states increases and the spectral peak shifts to the effective photosynthesis wavelength range, which enhances the probability of the photosynthesis processes.
