Both people and tomatoes come in different shapes and sizes. That is because every individual has a unique set of genetic variations—mutations—that affect how genes act and function. Added together, millions of small genetic variations make it hard to predict how a particular mutation will impact any individual.
Living beings need elements to develop properly. The study of ionomics measures and analyses the element accumulations in living organisms to determine which mineral nutrients are required and not required for growth.
Researchers have successfully sequenced the genome of previously extinct date palm varieties that lived more than 2,000 years ago. They did so using date palm seeds that were recovered from archaeological sites in the southern Levant region and radiocarbon-dated from the 4th century BCE to the 2nd century CE.
Tomatoes are an important and popular crop, but the tasty ketchup, salsa and pasta sauce they yield comes at a price: overuse of chemical fertilizers. Now, researchers report they have recruited a fungus to bolster fertilizer efficiency, meaning tastier tomatoes can be grown with less fertilizer.
Scientists investigating the genetics of chilli pepper species have discovered a whole host of new chilli hybrids that can be grown by crossing domesticated peppers with their wild cousins. This will allow plant breeders to create new varieties that have better disease resistance and could increase productivity.
Over 400 people from around the world got online at the same time to listen to international experts discuss the status and challenges surrounding conserving, exchanging and using the diversity of fruits and vegetables in 2021, the International Year of Fruits of Vegetables (IYFV).
A balanced nutritional diet rich in minerals, antioxidants, and vitamins is of vital importance for human health. Fruits and vegetables are rich sources for most of these dietary phytochemicals and micronutrients. However, today’s most common diets consist mainly of starchy staples and less of nutrient-rich foods or fruits and vegetables, particularly in the developing world. Keeping in view that the UN General Assembly designated the year 2021 as the International Year of Fruits and Vegetables.
Tomatoes are one of the most popular types of fresh produce consumed worldwide, as well as being an important ingredient in many manufactured foods. As with other cultivated crops, some potentially useful genes that were present in its South American ancestors were lost during domestication and breeding of the modern tomato, Solanum lycopersicum var. lycopersicum. Because of its importance as a crop, the tomato genome sequence was completed and published as long ago as 2012, with later additions and improvements. Now researchers have produced high-quality genome sequences of two wild ancestors of tomato from Peru, Solanum pimpinellifolium and Solanum lycopersicum var. cerasiforme.
In the strawberry nursery industry, a nursery’s reputation relies on their ability to produce disease- and insect-free plants. The best way to produce clean plants is to start with clean planting stock. Many nurseries struggle with angular leaf spot of strawberry, a serious disease that can result in severe losses either by directly damaging the plant or indirectly through a violation of quarantine standards within the industry.
Most legume species have compound leaves with multiple joined units termed leaflets, and the geometry of leaflets (the spatial structure and organization of leaflets) largely determines the compound leaf shape, which has been broadly recognized in model compound-leafed species.
