A Quadratic Regression Model to Quantify Plantation Soil Factors That Affect Tea Quality
Tea components (tea polyphenols, catechins, free amino acids, and caffeine) are the key factors affecting the quality of green tea. This study aimed to relate key biochemical substances in tea to soil nutrient composition and the effectiveness of fertilization. Seventy tea samples and their corresponding plantation soil were randomly collected from Xinyang City, China. The catechins, free amino acids, and caffeine in tea were examined, as well as the soil pH, nitrate (-N), ammonium (-N), available phosphorus (AP), available potassium (AK), and soil organic matter (SOM). The ordinary kriging was employed to visualize the spatial variation characteristic by ArcGIS. A quadratic regression model was used to analyze the effects of the soil environment on the tea. The results showed that the soil pH of the study area was suitable for cultivating tea plants. The relationship between soil pH and tea polyphenols and catechins presented the U-shape curve, whereas the soil pH and -N and the free amino acids, the soil pH, and caffeine presented the inverted U-shape curve. Soil management measures could be implemented to control the soil environment for improving the tea quality. The combination of the macro metrological model with individual experimentation could help to analyze the detailed influence mechanisms of environmental factors on plant physiological processes.- 5 December 2021

CsICE1 Functions in Cold Tolerance by Regulating Polyamine levels May through Interacting with Arginine Decarboxylase in the Tea Tree
Background: The identification of C-repeat binding factor (CBF), and the characterization as an inducer of CBF Expression 1 (ICE1), and a major activator for C-repeat binding factor, were important breakthroughs in the cold signaling network. Methods: In the present study, the full length cDNA of ICE1 was isolated from the tea tree (Camellia sinensis). CsICE1 protein was located in the cell nucleus as revealed by subcellular localization analysis. To investigate the biological functions of CsICE1, a transgenic line fused with the CsICE1 gene in Arabidopsis thaliana (arabidopsis) was generated by the floral dip method. Results: The CsICE1 was expressed differentially in various tea tree tissues, mostly in buds and leaves, and the transcript level of CsICE1 was increased after 1 h and peaked at 2 h under cold treatment. Transcription activity assay indicated that the spermine synthase (SPMS) and arginine decarboxylase (ADC) genes were possible targets of CsICE1. In addition, the values of net photosynthetic rate, transpiration rate, stomatal conductance in transgenic lines declined by less extent than wild-type plants under low temperatures. Furthermore, transcript levels of ADC genes in the transgenic lines had no apparent alteration under normal growth conditions but substantially increased under cold conditions, consistent of changes in free polyamine levels. Taken together, these results demonstrated that CsICE1 plays a positive role in cold tolerance, which may be due to the modulation of polyamine levels through interacting with CsADC.
