Endogenous formation of nitroxyl has been discovered by real-time detection in plant cells. Evidence shows that nitroxyl has a specific accumulation pattern different from nitric oxide in response to senescence- and hypoxia-induced redox shifts.
Species databases are critical tools for biologists and conservationists around the world, but a number of problems, including lack of common standards, are causing issues that even include the miscategorization of species as extinct when they are not.
Extant asterids comprise over 80,000 species of flowering plants. A fossil fruit from western North America shows that the lamiid clade of asterids diverged over 80 million years ago.
Comparative genomic analysis of 350 plant species reveals that cell-surface and intracellular immune receptor gene families co-expand or co-contract. This suggests an evolutionary relationship between the two branches of the plant immune system.
Vitamin D insufficiency is a major public health problem requiring dietary fortification and supplement solutions. This study produced gene-edited tomato lines that accumulate provitamin D3 in fruits, offering a new dietary source of vitamin D3.
This analysis looks at water use efficiency within and across multiple regions with different plant functional types, and finds that water use efficiency values tend to converge for some types despite distinct geographic and climatic zones.
