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: Octocrylene sunscreen is widely present in different environments. This study investigates its adverse effects on terrestrial plants and soil fauna. The results show that octocrylene negatively affects seed germination, root elongation, and cell division in Allium cepa, as well as avoidance behavior and oxidative stress in Eisenia fetida. The presence of octocrylene in soil fertilization and irrigation water may have a negative impact on the survival of species relying on the soil.

Summary: This study assesses the susceptibility of Allium cepa to trifloxystrobin and finds that it has toxic effects on the plant's physiology, cytogenetics, biochemistry, and anatomy. Trifloxystrobin inhibits the growth of the onion, induces chromosomal abnormalities and micronucleus formation, and negatively impacts cellular structure and biochemical processes. These toxic effects are dose-dependent.

Summary: Nitrogen is essential for onion growth, with demand varying based on yield and local nitrogen sources. Efficient nitrogen management practices include slow-release fertilizers, split applications, and band application to improve nitrogen use efficiency. Increased nitrogen availability can enhance bulb size, but excess nitrogen may lead to storage issues like decay.

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 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.

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: Intrinsically disordered peptides can form biomolecular condensates through liquid-liquid phase separation, which have diverse roles in cells, including inducing large-scale changes in membrane morphology. Coarse-grained molecular dynamics simulations reveal the physical principles governing membrane remodeling by condensates, with variations in interaction strengths leading to various observed membrane transformations. Insights from this study provide crucial guidance for designing (bio)polymers to manipulate membrane morphology in applications such as drug delivery and synthetic biology.

Summary: The aim of the studies was to evaluate the effects of acetic acid treatments on the quality of stored onion seeds. Seeds of two samples were soaked in different concentrations of acetic acid solutions and subjected to storage at two different temperatures. The results showed that treating onion seeds with acetic acid solutions reduced their infestation with fungi and did not have any adverse effect on germination and vigour of stored seeds.

Summary: A glossy mutant lacking an epicuticular wax layer was identified in the ?-irradiated M2 mutant population of the onion cultivar Bhima Super. The mutant displayed poor accumulation of wax crystals, primarily near the stomata. Gene expression analysis revealed downregulation of wax biosynthesis genes in the glossy mutant. These findings contribute to our understanding of wax biosynthesis in onions and provide a foundation for utilizing the glossy mutant trait for breeding programs.
