Summary: Genome dominance is observed in wide hybrids, where one parental genome becomes dominant over the other, leading to unequal retention of parental chromosomes in successive generations. Female meiotic drive is identified as the key factor underlying this dominance, with variations in strength across different chromosome segments.

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: 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: The genus Allium contains nearly 1000 different species, with onions and garlic being the most important edible plants that are cultivated and consumed globally. However, due to various constraints such as biennial nature, high crossability, and limited reproductive capacity, these plants have not received systematic and focused research. Induced mutagenesis is the best choice for creating genetic variation, especially in the context of climate change, to develop varieties with better adaptability to nutrient and growth conditions.

Summary: The efforts to understand the ideal state of health have led to the development of various treatment and healing systems across the world. Onion, a commonly used vegetable, has been traditionally used as a nutraceutical and medicinal plant with multiple benefits, but its importance as a traditional remedy is not widely known. Now, there is a growing focus on evaluating the medicinal values of onions and promoting the use of plant-based nutraceuticals. The use of vegetables and fruits as part of recommended dietary plans to prevent and manage common metabolic and lifestyle-related diseases is gaining prominence. This information about onions as a traditional medicine is significant in disseminating knowledge about this widely consumed but less researched vegetable crop in India.

Summary: The intake of diets with higher sodium and lower potassium has been considered a leading factor for the development of hypertension. Among fruits and vegetables, onion could be the ideal option as it contains high potassium content. Therefore, the evaluation of Indian onion cultivars for potassium and sodium content is important for preventing hypertension in the Indian population.

Summary: Onion, an important bulbous vegetable crop used in almost every Indian kitchen, has not seen much hybrid development in India and other developing countries. Future research should focus on identifying male sterile lines using modern biotechnological tools to enhance the productivity of commercial onion hybrids. Utilizing molecular markers distinguishing cytoplasm and linked to the restorer of male sterility will be important for the development of commercial hybrids in the public sector.
