The detrimental impact of pesticides on non-target organisms is one of the most urgent concerns in current agriculture. Double-stranded RNAs (dsRNAs) represent the most species-specific class of pesticides to date, potentially allowing control of a target pest without effecting other species.
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.
A recent work describes a new rapid ‘leaf-disk assay’ that uses chlorophyll fluorescence emissions to determine whether a weed is resistant to various systemic and contact herbicides.
Eucalyptus, a pest-resistant evergreen valued for its hardy lumber and wellness-promoting oil, can be genetically modified not to reproduce sexually, a key step toward preventing the global tree plantation staple from invading native ecosystems.
Increasing temperatures, changing rainfall patterns, and extreme weather events influence crop yields and where crops can live. These events limit the number of crops humans can use.
By 2050 global warming could reduce crop yields by one-third. Researchers have identified a gene that could put the genie back in the bottle.
New research from scientists offers a glimpse of how female gametes’ cell fates are determined and shows promise for future progress in plant breeding.
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 think that climate change may have greater impact the largest trees in tropical forests, and the death of these giants has a major impact on the forest, but because these monumental trees are few and far between, almost nothing is known about what causes them to die.
