“…We observed less decrease in light absorptance, increase in light reflectance, and lower transmittance in K. obovata than in B. gymnorhiza during CDNT (Table 3 and Supplementary Table 3). Such changes in leaf optical properties can be due to the PSII antenna-size and reducing-side heterogeneity, chlorophyll degradation, and accumulation of epicuticular waxes (Laxman et al, 2013; Belgio et al, 2014; Marchin et al, 2014; Bukhanov et al, 2020).…”

Cold waves restrict the distribution of mangroves. This study examined the contribution of PSII heterogeneity and stomatal functioning to sustaining photochemistry and photoprotection in mangroves during a cold wave. We exposed eight populations of Kandelia obovata (cold-tolerant) and, Bruguiera gymnorhiza (cold-susceptible) from different latitudes to 27/20°C (favorable) and 10/3°C (chilling; simulated cold wave) day and night temperatures. Multiple trait responses imply that cold waves affected K. obovata the least. Significant changes in chlorophyll fluorescence transients (photosystem II [PSII]) with a slight decrease in the redox status of P700 (photosystem I [PSI]) imply a greater impact of a cold wave on PSII. During the cold wave, photochemical efficiency of PSII, efficiency of the water-splitting complex, light absorptance, stomatal pore area, cyclic electron flow, nonphotochemical quenching, and number of active PSIIα and PSII QB reducing centers decreased, while light transmittance, night respiration, and inactive PSII QB nonreducing, PSIIβ, and γ centers increased in both species. The population of K. obovata from the coldest latitudinal site (Fujian, China) was least affected by cold wave due to local evolutionary adaptations. Modulation of PSII heterogeneity and stomatal functioning is important to sustaining photochemistry and photoprotection in mangroves to cope with cold waves.

“…Some recent studies have shown that the epicuticular wax on the leaves of gray wheat and blue spruce is directly responsible for plant coloration due to its unique photonic crystal nanostructure [ 6 ]. The epicuticular wax of these plants consists of nanotubes and nanorods with an outer diameter of 140–160 nm.…”

“…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.…”

“…They also have an ability to control both the speed of optical radiation in such structures [ 13 ] and the localization of electromagnetic waves [ 14 ]. Examples of these structures, such as iridoplasts in begonia [ 4 ], chloroplasts of Selaginella erythropus [ 5 ], bisonoplasts [ 15 ], giant chloroplasts [ 16 ], lamelloplasts [ 17 ], algae [ 18 ], epicuticular wax [ 6 ], and others [ 19 ], have been described in a number of studies.…”

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.

“…Edge effects interfere with the proportions of different aliphatic compounds in epicuticular waxes (BIANCHI; BIANCHI, 1990). Wax plays several roles in plants as repelling insects, conserving moisture and nutrients, and preventing fungal and bacterial contamination.…”

Forest fragmentation leads to various environmental problems. It causes edge effects that can decrease biodiversity, promote the growth of lianas, and affect the production of epicuticular wax. This study focuses on examining the secondary metabolites found in the epicuticular wax of Vismia guianensis leaves and investigating the impact of the edge effect on their production. We extracted and quantified the epicuticular wax and analyzed its constituents using gas chromatography coupled with a mass spectrometer. The amount of cuticular wax extracted from V. guianensis leaves ranged from 33.69 to 631.57 μg/cm². Individuals at the forest edge had the lowest wax content, averaging 250.96 μg/cm². On the other hand, individuals located in the interior of the forest had the highest values, with an average of 340.67 μg/cm² per surface unit. The analysis of the samples identified and quantified nine long-chain alkanes (C27 to C35) in the composition of the cuticular wax. The predominant compound in the wax of all individuals was nonacosane alkane (C29). Interestingly, the individuals within the forest fragment exhibited less diversity of compounds compared to those at the forest edge.
