Pyropia tenera, also known as gim or nori, is a red algal species in the genus Pyropia. The specific name, tenera, means "delicate" and alludes to its small size. It typically grows to lengths between 20 and 50 cm. It is most typically found in the western Pacific Ocean and the Indian Ocean.
Following a major reassessment of the genus in 2011, many species previously included in Porphyra have been transferred to Pyropia: for example Pyropia tenera, Pyropia yezoensis, and the species from New Zealand Pyropia rakiura and Pyropia virididentata, leaving only five species out of seventy still within Porphyra itself. [16]
The ability of Pyropia species to adapt to deal with these stresses makes them heavily studied organisms. One of the threats to Pyropia is fungal infections by Alternaria sp. ZL-1, which has been observed in farming environments on Pyropia yezoensis [6]. The fungus kills Pyropia cells and leaves brown rust-like spots on the outside of the blades.
The model can be easily generalized to relax these and other constraints. [17] These rates are likely to differ in non experimental settings. The models also require that N t μ >> 1 where N t is the total number of organisms. This assumption is likely to hold in most realistic or experimental settings.
California’s eco-bureaucrats halted a wildfire prevention project near the Pacific Palisades to protect an endangered shrub. It’s just the latest clash between fire safety and conservation in ...
Brazil's agricultural research agency Embrapa, which helped turn the country into a leading grains exporter, is preparing a 12-year research program that could do the same for cannabis cultivation ...
Stentor coeruleus, used in molecular biology (its genome has been sequenced), [5] and is studied as a model of single-cell regeneration.; Dictyostelium discoideum, used in molecular biology and genetics (its genome has been sequenced), and is studied as an example of cell communication, differentiation, and programmed cell death.
Alphabet plans to spend $16 billion to $18 billion in the first quarter, a far bigger number than the roughly $6 million DeepSeek said it spent on the final training run to develop its AI model.
