The capability of 5, 10, 15 mM γ-aminobutyric acid (GABA) to improve the postharvest quality and antioxidant system strawberry was evaluated in this study. application GABA had no effect on fruit skin color firmness. weight loss fruits treated with 10 significantly lower than control. treatments resulted higher levels total soluble sugar, titratable acid, SOD CAT activities being most significant effect. Specifically, induced accumulation fructose, oxalic succinic acid. Besides, increased content anthocyanins flavonoids, DPPH radical scavenging activity fruits. GABA-treated especially at 5 displayed less ROS MDA. These data suggested that might be a promising strategy marketability strawberry.

Crop Performance and Photochemical Processes Under a UV-to-Red Spectral Shifting Greenhouse: A Study on Aubergine and Strawberry

Agriculture, Journal Year: 2025, Volume and Issue: 15(6), P. 569 - 569

Published: March 7, 2025

Light quality is a fundamental factor in greenhouses, since different light wavelengths affect plant photosynthesis and photomorphogenesis differently, they thus crop growth productivity. The aim of this study was to evaluate the effect an experimental greenhouse cover film with UV-to-Red spectral shifting properties on photosynthesis, growth, fruit yield, two crops spanning over year-long cultural cycle: aubergines (Solanum melongena L.), as spring–summer crop, followed by strawberries (Fragaria × ananassa Duch.), autumn–spring crop. Trials were carried out multispan where sectors covered, each one diffusing polyethylene film: sector covered photoluminescent film, doped blend rare-earth elements partially converting UV solar radiation into Red wavelengths, while used control. At physiological level, affected chlorophyll fluorescence parameters related photochemistry which found be positively yield. Moreover, differential analysis fast Chlorophyll transients (or OJIP kinetics) showed that steps photochemical metabolism.

Regulation of Anthocyanins and Quality in Strawberries Based on Light Quality

Horticulturae, Journal Year: 2025, Volume and Issue: 11(4), P. 377 - 377

Published: March 31, 2025

Strawberry fruits accumulate nutritionally critical anthocyanins and phytochemicals through light=quality-dependent metabolic regulation. This review systematically examines spectral modulation strategies for enhancing anthocyanin biosynthesis fruit quality parameters. We demonstrate that dual red (660 nm) blue (450 irradiation optimally activates the flavonoid pathway, co-upregulating structural genes (CHS, F3H, DFR, ANS) regulatory factors (FaMYB10, FaHY5). Mechanistic analyses reveal light preferentially induces upstream phenylpropanoid enzymes (PAL, C4H, CHI), while enhances proanthocyanidin production differential induction of LAR ANR. Strategic supplementation with UV-C (254 nm, 1–2 kJ/m2/d) far-red (730 15 μmol·m−2·s−1) improves spatial distribution via stress-mediated epidermal accumulation. Spectral optimization further coordinates flavor development by (1) balancing sucrose–hexose ratios FaSPS1 modulation, (2) reducing organic acid content FaMYB44.2 suppression, (3) amplifying volatile esters (e.g., methyl anthranilate) SAAT induction. Postharvest treatment (4 kJ/m2) extends shelf life 30–35% microbial inhibition antioxidant system activation. Practical implementation frameworks propose phase-specific LED protocols related to vegetative growth (R:B = 3:1), flowering 1:1), maturation 4:1) stages integrated environmental sensors in controlled agriculture systems. These findings establish an actionable paradigm photonic crop management, synergizing molecular precision commercial horticultural operations achieve sustainable yield enhancement (projected 22–28% increase) nutraceutical enrichment.

The geomagnetic field (GMF) is a natural component of the biosphere, and, during evolution, all organisms experienced its presence while some evolved ability to perceive magnetic fields (MF). We studied response 14-3-3 proteins and plasma membrane (PM) proton pump H+-ATPase reduced GMF values by lowering intensity near-null (NNMF). Seedling morphology, activity content, protein binding PM phosphorylation, gene expression, ROS quantification were assessed in maize (Zea mays) dark-grown seedlings. Phytohormone melatonin also LG-MS/MS. Our results suggest that regulates H+-ATPase, NNMF conditions alter reducing proteins. This effect was associated with both reduction H2O2 downregulation genes coding for enzymes involved production scavenging, as well calcium homeostasis.

Fruit softening is a crucial factor that controls shelf life and commercial value. Pectate lyase (PL) has major role in strawberry fruit softening. However, the PL gene family not been comprehensively analyzed. In this study, 65 FaPL genes were identified octoploid genome. Subcellular localization prediction indicated FaPLs are mostly localized to extracellular cytoplasmic spaces. Duplication event analysis suggested expansion mainly driven by whole genome or segmental duplication. The members classified into six groups according phylogenetic analysis. Among them, FaPL1, 3, 5, 20, 25, 42, 57 had gradually increased expressions during development ripening higher expression levels fruits with less firmness than firmer fruit. This result these involved Furthermore, overexpression of FaPL1 significantly reduced firmness, ascorbic acid (AsA), malondialdehyde (MDA) content but obviously anthocyanins, soluble proteins, titratable acidity (TA), while it no apparent effects on flavonoids, phenolics, sugar content.
