“…Light is required for the photosynthetic process that provides the chemical energy needed for plant growth and productivity. Moreover, plant metabolism, gene expression and plant processes (e.g., movement of stomatal guard cells, abscission, mineral absorption, phototropism) are regulated or conditioned by light [ 66 , 67 , 68 , 69 ].…”

Fruit quality is certainly influenced by biotic and abiotic factors, and a main quality attribute is the external appearance of the fruit. Various possible agronomical approaches are able to regulate the fruit microenvironment and, consequently, improve fruit quality and market value. Among these, fruit bagging has recently become an integral part of fruits’ domestic and export markets in countries such as Japan, China, Korea Australia and the USA because it is a safe and eco-friendly technique to protect fruits from multiple stresses, preserving or improving the overall quality. Despite increasing global importance, the development of suitable bagging materials and, above all, their use in the field is quite laborious, so that serious efforts are required to enhance and standardize bagging material according to the need of the crops/fruits. This review provides information about the effects of bagging technique on the fruit aspect and texture, which are the main determinants of consumer choice.

“…Perhaps the most important entraining signal in plants is light. Plants use different classes of photoreceptors to sense the light environment and set the clock to the actual pace of day-night cycles [ 44 ]. These photoreceptors include PHYs and CRYPTOCHROMEs (CRYs), which transmit red and blue light signals, respectively [ 44 ].…”

“…Plants use different classes of photoreceptors to sense the light environment and set the clock to the actual pace of day-night cycles [ 44 ]. These photoreceptors include PHYs and CRYPTOCHROMEs (CRYs), which transmit red and blue light signals, respectively [ 44 ]. Mutations in both PHY and CRY photoreceptors have been shown to affect circadian period length in response to different light qualities [ 45 , 46 ] and the spatial expression pattern of PHY and CRY genes varies among tissues [ 47 , 48 , 49 ].…”

The plant circadian clock has a pervasive influence on many aspects of plant biology and is proposed to function as a developmental manager. To do so, the circadian oscillator needs to be able to integrate a multiplicity of environmental signals and coordinate an extensive and diverse repertoire of endogenous rhythms accordingly. Recent studies on tissue-specific characteristics and spatial structure of the plant circadian clock suggest that such plasticity may be achieved through the function of distinct oscillators, which sense the environment locally and are then coordinated across the plant through both intercellular coupling and long-distance communication. This review summarizes the current knowledge on tissue-specific features of the clock in plants and their spatial organization and synchronization at the organismal level.

“…Photoreceptors are divided according to its wavelength sensing. They are named phytochromes in response to red/far-red (R/FR) light; cryptochromes, phototropins, and zeitlupes when sensing blue/UV-A light; and UV-B photoreceptors (UVR8) when responding to UV-B ( Figure 1 ) [ 32 ]. Once photoactivated, photoreceptors interact with other players involved in light responses, such as ELONGATED HYPOCOTYL 5 (HY5), a photomorphogenesis promoting transcription factor, and the CONSTITUTIVE PHOTOMORPHOGENIC 1 ( COP1 ) - SUPPRESSOR OF PHYA-105 (SPA) complex, among others.…”

The development of almost every living organism is, to some extent, regulated by light. When discussing light regulation on biological systems, one is referring to the sun that has long been positioned in the center of the solar system. Through light regulation, all life forms have evolved around the presence of the sun. As soon our planet started to develop an atmospheric shield against most of the detrimental solar UV rays, life invaded land, and in the presence of water, it thrived. Especially for plants, light (solar radiation) is the source of energy that controls a high number of developmental aspects of growth, a process called photomorphogenesis. Once hypocotyls reach soil′s surface, its elongation deaccelerates, and the photosynthetic apparatus is established for an autotrophic growth due to the presence of light. Plants can sense light intensities, light quality, light direction, and light duration through photoreceptors that accurately detect alterations in the spectral composition (UV-B to far-red) and are located throughout the plant. The most well-known mechanism promoted by light occurring on plants is photosynthesis, which converts light energy into carbohydrates. Plants also use light to signal the beginning/end of key developmental processes such as the transition to flowering and dormancy. These two processes are particularly important for plant´s yield, since transition to flowering reduces the duration of the vegetative stage, and for plants growing under temperate or boreal climates, dormancy leads to a complete growth arrest. Understanding how light affects these processes enables plant breeders to produce crops which are able to retard the transition to flowering and avoid dormancy, increasing the yield of the plant.
