Integrated comparative transcriptome and physiological analysis reveals the metabolic responses underlying genotype variations in NH4+ tolerance

open access: yesFrontiers in Plant Science, 2023
Several mechanisms have been proposed to explain NH4+ toxicity. However, the core information about the biochemical regulation of plants in response to NH4+ toxicity is still lacking.

Transcriptome analysis of tea (Camellia sinensis) leaves in response to ammonium starvation and recovery

open access: yesFrontiers in Plant Science, 2022
The tea plant is a kind of ammonium-preferring crop, but the mechanism whereby ammonium (NH4+) regulate its growth is not well understood. The current study focused on the effects of NH4+ on tea plants.

The kinetics curve of nitrogen mineralization from perennial leaves litter decomposed by earthworm (Phretima californica)

open access: yesSains Tanah: Journal of Soil Science and Agroclimatology, 2020
The kinetics of N release during the process of decomposition of organic matter is influenced by organic matter quality, temperature, humidity, and decomposer. Acacia, coffee, salacca, and bamboo leaf litter are native plants and be the pioneer plants on

Nitrogen Source Matters: High NH4/NO3 Ratio Reduces Cannabinoids, Terpenoids, and Yield in Medical Cannabis

open access: yesFrontiers in Plant Science, 2022
The N form supplied to the plant, ammonium (NH4+) or nitrate (NO3–), is a major factor determining the impact of N nutrition on plant function and metabolic responses. We have hypothesized that the ratio of NH4/NO3 supplied to cannabis plants affects the

Silicon Mitigates Ammonium Toxicity in Cabbage (Brassica campestris L. ssp. pekinensis) ‘Ssamchu’

open access: yesFrontiers in Sustainable Food Systems, 2022
Ammonium (NH4+) toxicity hinders the cabbage yield because most subspecies or varieties exhibit extreme sensitivity to NH4+. Current knowledge indicates that silicon (Si) can alleviate or reverse the ammonium toxicity severity.

Treatment of ammonium in slaughterhouse wastewater by UASB technology combined with EGSB using anammox and PVA gel

open access: yesVietnam Journal of Science, Technology and Engineering, 2022
Slaughterhouse wastewater (SWW) possesses very high organic and nutrient concentrations and its residues are moderately solubilized, which leads to pollution affecting the environment and human health.
