Nitrogen-Regulated Theanine and Flavonoid Biosynthesis in Tea Plant Roots: Protein-Level Regulation Revealed by Multiomics Analyses
茶氨酸 黄酮类化合物 原花青素 茶树
2023/4/19
Theanine and flavonoids (especially proanthocyanidins) are the most important and abundant secondary metabolites synthesized in the roots of tea plants. Nitrogen promotes theanine and represses flavon...
The tea plant CsLHT1 and CsLHT6 transporters take up amino acids, as a nitrogen source, from the soil of organic tea plantations
茶树 CsLHT1 CsLHT6 转运蛋白 有机茶
2023/4/20
Organic tea is more popular than conventional tea that originates from fertilized plants. Amino acids inorganic soils constitute a substantial pool nitrogen (N) available for plants. However, the amin...
Remobilization of Nitrogen from Vegetative Parts to Sprouting Shoots of Young Tea (Camellia sinensis L.) Plants
Isotope dilution Nitrogen Nitrogen balance Origin of nitrogen Remobilization
2009/7/30
Uptake, distribution and redistribution of 15N-nitrogen in young tea plants were examined during the first flush season in order to know the seasonal changes in nitrogen uptake and the origin of nitro...
Behavior of Inorganic Nitrogen in Tea Field Soils Heavily Applied with Nitrogen and Changes in Amino Acid Content of the First Crop Accompanying the Reduction of Nitrogen
Amino acid content Heavy application of nitrogen Inorganic nitrogen Soil solution Tea plants
2009/7/29
We investigated the behavior of nitrogen heavily applied to inter-row spaces of the fields and the deterioration in amino acid contents caused by the reduction in nitrogen. The concentrations of inor...
Influences of Heavy Application of Nitrogen on Soil Acidification and Root Growth in Tea Fields
Heavy application of nitrogen Root growth Soil acidification Soil solution Tea plants
2009/7/29
We surveyed the actual levels of nitrogen application in the productive region of green tea in northern Mie prefecture and investigated the physico-chemical properties of the soils and root growth in ...
Seasonal Changes in Uptake, Distribution and Redistribution of 15N-Nitrogen in Young Tea (Camellia sinensis L.) Plants
Camellia sinensis First flush shoots Isotope dilution Seasonal change
2009/7/28
In order to know the seasonal changes in nitrogen requirement of tea plants, hydroponically-grown young plants were pulse-labelled with 15N during each month throughout the year in a glasshouse. Upta...
Stratiform Analysis of Growth, Total Nitrogen, Free Amino Acid and Neutral Detergent Fiber Concentration of New Shoots in Mechanically-plucked Tea (Camellia sinensis L.) Bush
Camellia sinensis Free amino acid Neutral detergent fiber Rail-tracking tea plucker Stratified clip method
2009/7/28
Some factors which might relate to yield and quality were inverstigated by stratiform analysis in order to estimate the most suitable plucking height in the mechanically-plucked tea bush. During a per...
Changes in Nitrogen Uptake with Aging and Under Heavy Application of Nitrogen in Tea Plants
Heavy application of nitrogen Nitrogen absorption Tea plants
2009/7/24
Nitrogen absorption by mature tea plants was examined under different nitrogen levels. The annual increase rate of dry matter of five-year-old plants was 1.49 when no nitrogen was applied and increase...
Suitable Level of Nitrogen Fertilizer for Tea (Camellia sinensis L.) Plants in Relation to Growth, Photosynthesis, Nitrogen Uptake and Accumulation of Free Amino Acids
Arginine Camellia sinensis Critical level Excess nitrogen Free amino acid Green tea
2009/7/22
The physiological responses of pot-grown tea plants to various levels of nitrogen fertilizer were investigated to determine the suitable level of nitrogen for tea plants. Defining an arbitrary unit of...
