Acclimation of circadian rhythms in woodland strawberries (Fragaria vesca L.) to Arctic and mid-latitude photoperiods
Though many abiotic factors are constantly changing, the photoperiod is a predictable factor that enables plants to time many physiological responses. This timing is regulated by the circadian clock, yet littl... (Source: BMC Plant Biology)

Photoantimicrobial chitosan-gelatin-pomegranate peel extract films for strawberries preservation: From microbiological analysis to in vivo safety assessment
This study aimed to investigate the application of biopolymeric materials (chitosan, gelatin, and pomegranate peel extract as photosensitizer) and antimicrobial photodynamic therapy (aPDT) on the physicochemical and microbial safety of strawberries. The photosensitizer potential of the materials was confirmed by a light-dose-dependent photobleaching profile. The application of light (525 nm; 50 J cm-2) decreased by >2 log CFU mL-1 the survival of Staphylococcus aureus on the surface of the photoactive-biopolymeric films. Moreover, the materials did not present in vivo cytotoxicity using Danio rerio (Zebrafish) as well a...

Toxicological analysis of metals content in agro-food wastes as possible supplement in animal feed
Nat Prod Res. 2023 Sep 14:1-6. doi: 10.1080/14786419.2023.2257361. Online ahead of print.ABSTRACTThe agro-food surplus is considered the most abundant renewable resource, interesting for the economic and environmental impact, with a possible employment in different productive fields such as supplement in animal feed. For a safe and effective enhancement of agro-food wastes it is needed a toxicological analysis before of their employment, to avoid potential risks to animals, humans and environment. The purpose of this study was to evaluate the metals content (Cu, Fe, Zn, Mg, Na, K, Ca, Mn, Se, Zn, Co, Ni, V, Sb, Mo, Cr and ...

Effects of preharvest chitosan-Myrtus communis essential oil composite and postharvest nanocellulose on quality of strawberry
The objective of this study was to investigate the effects of preharvest chitosan-Myrtus communis essential oil composite (1.5 and 3.0 %) and postharvest nanocellulose (0.3 and 0.6 %) on the quality of strawberries. The gas chromatography-mass spectrometry (GC/MS) analysis led to identification of 32 compounds in the Myrtus communis essential oil. The study showed that using CHS-ES composite coating for foliar application could increase the lifespan of the fruit by up to 24 days. This is because it increases the levels of components, such as phenol content (TPC) total flavonoids content (TFC) vitamin C, firmness and SSC. I...

Sensors, Vol. 23, Pages 7639: Real-Time Detection of Strawberry Ripeness Using Augmented Reality and Deep Learning
ivan
Currently, strawberry harvesting relies heavily on human labour and subjective assessments of ripeness, resulting in inconsistent post-harvest quality. Therefore, the aim of this work is to automate this process and provide a more accurate and efficient way of assessing ripeness. We explored a unique combination of YOLOv7 object detection and augmented reality technology to detect and visualise the ripeness of strawberries. Our results showed that the proposed YOLOv7 object detection model, which employed transfer learning, fine-tuning and multi-scale training, accurately identified the level of ripeness of each s...

Cells with extra genomes may help tissues respond to injuries —and species survive cataclysms
When Vicki Losick got her Ph.D. and joined a fruit fly lab at the Carnegie Institution for Science in 2008, its head announced that he expected his postdocs to launch new fields of inquiry. She chose a then-fashionable focus: stem cells, versatile cells that specialize into other cell types and play critical roles in embryonic development and the renewal of adult tissues. Losick wondered whether they also help in wound repair. So, she and another postdoc, Don Fox, began stabbing fruit flies with a tiny needle, hoping to document stem cells coming to the rescue.
Instead, the two postdocs, working independently, saw ot...

Online ahead of print.ABSTRACTIn this work, two plant foods, strawberry and tomato, were subjected to exposure to metals from synthetic airborne particles in a closed chamber experiment. The synthetic particles were obtained in the laboratory. Within the closed chamber, particles were added and recirculated for 4 days in a turbulent air stream, causing deposition on the different parts of the plants. They were evaluated because of their increasingly frequent cultivation in urban gardens of cities. The main objectives were to determine whether the spec...
