Free-standing, robust, and transparent bioplastics were obtained by blending cellulose naringin at different proportions. Optical, thermal, mechanical, antioxidant, antimicrobial properties systematically investigated. In general, the incorporation of produced important UV blocking plasticizer effects good antioxidant antibacterial properties. Moreover, barrier characterized determination their water oxygen transmission rates, finding that both parameters decreased increasing content...
The cuticle covering plants' aerial surfaces is a unique structure that plays key role in organ development and protection against diverse stress conditions. A detailed analysis of the tomato colorless-peel y mutant was carried out framework studying outer surface reproductive organs. peel lacks yellow flavonoid pigment naringenin chalcone, which has been suggested to influence characteristics function cuticular layer. Large-scale metabolic transcript profiling revealed broad effects on both...
Plant trichomes play important protective functions and may have a major influence on leaf surface wettability. With the aim of gaining insight into trichome structure, composition, function in relation to water-plant interactions, we analyzed adaxial abaxial holm oak (Quercus ilex) as model. By measuring water potential 24 h after deposition drops onto surfaces, evidence for penetration through upper side was gained young mature leaves. The structure chemical composition (always present)...
Summary In addition to the role of cell wall as a physical barrier against pathogens, some its constituents, such pectin‐derived oligogalacturonides (OGA), are essential components for elicitation defence responses. To investigate how modifications pectin alter responses, we expressed fruit‐specific Fragaria × ananassa methyl esterase FaPE1 in wild strawberry vesca . Pectin from transgenic ripe fruits differed wild‐type with regard degree and pattern esterification, well average size...
The mechanical characteristics of the cuticular membrane (CM), a complex composite biopolymer basically composed cutin matrix, waxes, and hydrolysable polysaccharides, have been described previously. biomechanical behaviour quantitative contribution polysaccharides investigated here using as experimental material mature green red ripe tomato fruits. Treatment isolated CM with anhydrous hydrogen fluoride in pyridine allowed selective elimination attached to or incrusted into matrix. Cutin...
Summary In this study, growth‐dependent changes in the mechanical properties of tomato ( Solanum lycopersicum ) cuticle during fruit development were investigated two cultivars with different patterns growth and accumulation. The determined uniaxial tensile tests using strips isolated cuticles. Changes functional groups chemical components analysed by attenuated total reflectance–Fourier transform infrared ATR ‐ FTIR ). early stages are characterized an elastic cuticle, viscoelastic...
The epidermis plays a pivotal role in plant development and interaction with the environment. However, it is still poorly understood, especially its outer epidermal wall: singular wall covered by cuticle. Changes cuticle cell structures are important to fully understand their functions. In this work, an ultrastructure immunocytochemical approach was taken identify changes main components of during tomato fruit development. A thin uniform procuticle already present before set. During...
Abstract Hydroxycinnamic acids present in plant cuticles, the interphase and main protective barrier between environment, exhibit singular photochemical properties that could allow them to act as a UV shield. Here, we employ transient absorption spectroscopy on isolated cuticles leaf epidermises study situ photodynamics of these molecules excited state. Based quantum chemical calculations p -coumaric acid, phenolic acid cuticle, propose model which cuticle phenolics display photoprotective...
Fruit cracking, a widespread physiological disorder affecting various fruit crops and vegetables, has profound implications for quality marketability. This mini review delves into the multifaceted factors contributing to cracking emphasizes pivotal roles of environmental agronomic in its occurrence. Environmental variables such as temperature, relative humidity, light exposure are explored determinants influencing susceptibility. Furthermore, significance mineral nutrition plant growth...
The surface of peach (Prunus persica 'Calrico') is covered by a dense indumentum, which may serve various protective purposes. With the aim relating structure to function, chemical composition, morphology, and hydrophobicity skin was assessed as model for pubescent plant surface. Distinct physicochemical features were observed trichomes versus isolated cuticles. Peach cuticles composed 53% cutan, 27% waxes, 23% cutin, 1% hydroxycinnamic acid derivatives (mainly ferulic p-coumaric acids)....
Fruit cuticle composition and their mechanical performance have a special role during ripening because internal pressure is no longer sustained by the degraded cell walls of pericarp but directly transmitted to epidermis which could eventually crack. We studied fruit growth, modifications its biomechanics, cracking in tomato; tomato has been considered model system for studying fleshy growth ripening. Tomato major disorder that causes severe economic losses and, cherry tomato, crack...
Waterproofing of the aerial organs plants imposed a big evolutionary step during colonization terrestrial environment. The main plant polymers responsible water repelling are lipids and lignin, which play also important roles in protection against biotic/abiotic stresses, regulation flux gases solutes mechanical stability negative pressure, among others. While lipids, non-polymerized cuticular waxes together with polymerized cutin, protect outer surface, lignin is confined to secondary cell...
Plant cuticles have been used as models to produce hydrophobic films composed of sodium alginate, the fatty acid fraction tomato pomace agrowaste, and beeswax. The fabrication process consisted blending components in green solvents (water ethanol) a subsequent thermal treatment (150 °C, 8 h) polymerize unsaturated polyhydroxylated acids from pomace. When alginate were blended, free-standing obtained. These characterized evaluate their morphological (SEM), chemical (solid-state NMR,...
A method consisting of the alkaline hydrolysis tomato pomace by-products has been optimized to obtain a mixture unsaturated and polyhydroxylated fatty acids as well non-hydrolysable secondary residue. Reaction rates activation energy were calculated reduce costs associated with chemicals consumption. Lipid fractions chemically (infrared (IR) spectroscopy, gas chromatography/mass spectrometry (GC-MS)) thermally (differential scanning calorimetry (DSC), thermogravimetric analysis (TGA))...
