Summary: This study evaluated the influence of gamma-radiation on the morphology, properties, and performance of bioplastic produced from onion bulb. The results showed that higher doses of radiation led to rougher and more irregular film surfaces, increasing hydrophobicity. Radiation also changed the structure and chemical groups of the samples, increasing crystallinity and the interaction with hydroxyl groups. However, radiation did not proportionally change the mechanical properties of the films. Furthermore, there was no mutagenicity or cytotoxicity in the films even after higher doses of gamma-irradiation.

Summary: In the coming years, there is an expected increase in interest among European Union countries for the use of Welsh onion, a lesser-known vegetable from the Far East. As a result, growers may seek advice on seed physiology and commercial production. This article offers information on various aspects including the origin of the species, botanical characteristics, breeding directions, seed production methods, companies involved, seed dormancy, storage methods, crop utilization, and market responses to promotional efforts.

Summary: Onions, rich in bioactive compounds, have shown antiobesity effects according to a systematic review and meta-analysis. Clinical trials evaluating the antiobesity effects of onions in obese subjects were selected and analyzed. The results indicate that onion intake can reduce body weight, BMI, waist circumference, and triglyceride levels, with onion peel particularly effective.

Summary: Onions are a valuable vegetable-spice crop in India but are susceptible to diseases caused by fungi, bacteria, viruses, and nematodes. Anthracnose, caused by Colletotrichum spp., is a major issue as it severely affects bulb production. Twister disease is a common problem in onion production, particularly in humid regions, reducing productivity and value. This review provides updated knowledge on onion anthracnose, including the pathogen, disease cycle, infection pathways, and management techniques to benefit growers.

Summary: This study reports the successful establishment of a CRISPR/Cas9-mediated genome editing protocol in onions, using the AcPDS gene as an example. Through transformation and cultivation of calli, different phenotypes were observed in regenerated shoots, with some exhibiting albino or chimeric characteristics. PCR and deep amplicon sequencing confirmed the successful editing of the AcPDS gene.

Summary: The bacterial communities in different microhabitats of Himalayan onion showed varying levels of diversity, with the rhizosphere having the highest diversity. A unique feature of the microbiome was its high evenness in taxonomic distribution, and plant-specific signature bacteria like Pseudomonas were identified. The study provides insights into the microbiome of the Allium genus and can facilitate comparisons with domesticated relatives for bioresource mining.

Summary: While fish effluents have been proven as effective fertilizers for crop production, their use is prohibited in organic production according to current European regulations. This study investigated the effects of filtered and unfiltered fish effluents on onion yield, soil nutrients, and microbiome compared to composted horse manure. The addition of fish effluents, particularly unfiltered fish water or sludge, enhanced soil fertility and resulted in the highest nitrate content. Fertilization with fish effluents resulted in higher yields than the manure, highlighting their superior performance.

Summary: The availability of water and nitrogen in the soil affects the metabolism of onion bulbs, particularly the synthesis of metabolites and bioactive compounds. Understanding the effects of different water levels and nitrogen fertilization is important to optimize the quality of onions. This research aimed to study the effects of hydric stress and nitrogen fertilization on the physicochemical and bioactive properties of onions.

Summary: Onion is an important vegetable crop with numerous health-promoting properties. As climate change poses challenges to agriculture, the preservation and utilization of onion germplasm is crucial for sustainable agriculture and food security. Genetic diversity stored in global onion germplasm collections can be harnessed to develop climate-resistant varieties. Collaboration at international and inter-institutional levels is important for sharing and utilizing onion genetic resources to solve future agricultural challenges.

Summary: The red color of onion bulbs is caused by anthocyanins, which are regulated by a protein called AcB2. AcB2 interacts with another protein called AcMYB1 to enhance the regulation of anthocyanin biosynthesis. This discovery provides a theoretical basis for breeding onions with higher anthocyanin contents.
