Article Synopsis
- Boron (B) is crucial for plant growth, but its toxicity effects in citrus trees, particularly pomelo, are not well understood, prompting a study on its transport mechanisms from soil to fruit.* -
- The field experiment compared B-free conditions to those with fertilization and found that excess B led to toxicity signs like chlorosis, reduced leaf biomass, and a significant drop in fruit yield by over 45% due to lower fruit load and weight.* -
- Additionally, B toxicity altered mineral nutrient concentrations, decreased fruit quality indicators (like vitamin C and total sugars), and heightened B accumulation in leaves compared to fruits, underscoring the need for better B management in citrus cultivation.*
Article Synopsis
- Citrus fruit is recognized as a superfood with significant nutritional benefits, and this study aims to conduct a comprehensive quality assessment of various citrus cultivars to enhance sustainable production and use.
- The research involved analyzing nine different citrus fruits for their morphological, juice properties, and mineral content in the peel, pulp, and seeds, while also evaluating their overall fruit quality index using two different methods.
- Results revealed considerable variations in quality characteristics among cultivars, with Ningmeng fruits exhibiting high vitamin C but low total soluble solids, while Jinju fruits displayed the highest total soluble solids and phenolic content, leading to distinct groupings of the fruits based on quality parameters.
Regulation of magnesium and calcium homeostasis in citrus seedlings under varying magnesium supply.
Plant Physiol Biochem
November 2023
Article Synopsis
- Magnesium (Mg) and calcium (Ca) are crucial nutrients for plant growth, but their roles and relationships in citrus plants under different Mg supply levels are not fully understood.
- The study focused on Citrus sinensis seedlings, which were grown in conditions of Mg deficiency and sufficiency, revealing that Mg deficiency led to reduced root and shoot growth, especially impacting branch organs.
- Results showed that Mg deficiency decreased the concentrations of both Mg and Ca in the seedlings while altering their distribution across different organs, with a notable increase in the Ca/Mg ratio, indicating a significant interaction between Mg supply and nutrient homeostasis.
Article Synopsis
- Magnesium (Mg) is crucial for plant growth, but how citrus plants adapt to Mg deficiency is not well understood; this study investigates this through controlled experiments.
- Researchers found that Mg deficiency significantly reduced plant biomass and affected Mg concentration and distribution across different organs, along with decreased root growth.
- Under deficiency, Mg forms changed, with increased mobility in roots but decreased in leaves, suggesting altered chemical forms impacted transport and absorption abilities, potentially providing strategies to enhance Mg availability in citrus.
Article Synopsis
- - The study investigated how magnesium (Mg) supply affects growth differences in parent and branch organs of citrus plants, using Mg-deficient and Mg-sufficient conditions for seedlings.
- - Results showed that Mg deficiency led to a significant reduction in plant biomass, particularly in branch organs, by impairing photosynthesis and carbohydrate accumulation, while branch leaves adapted better to the deficiency than parent leaves.
- - The findings indicate that Mg mobility is crucial for physiological metabolism differences between plant organs, suggesting the need for optimized Mg management in sustainable citrus farming.
Nitrogen (N) and potassium (K) are essential macronutrients for plants growth; however, the mechanism by which K mediates negative effects on ammonium-sensitive plants is still poorly understood. We hypothesized that K supplies may enhance antagonistic ammonium stress while improving nitrate nutrition function, which wheat seedlings were grown in sand culture in the presence of two N forms (ammonium; nitrate) supplied at two rates (2, 10 mmol L) and three K levels (0.5, 5, 15 mmol L).

This study was to test the efficacy of ECH-enriched extract of Cistanche tubulosa in the treatment of dextran sulphate sodium (DSS)-induced colitis, a preclinical model of ulcerative colitis. Oral administration of ECH extract significantly suppresses the development of acute colitis, indicated by lowering disease activity index (p < 0.

- Cistanche deserticola (C. deserticola) is an herbal medicine commonly used to treat irritable bowel syndrome and constipation, with echinacoside (ECH) being a key active ingredient.
- A study using the MODE-K intestinal epithelial cell line revealed that ECH promotes cell growth and increases survival by reducing apoptosis when cells are exposed to harmful substances like H(2)O(2) or inflammatory cytokines.
- The research found that ECH's protective effects depend on the up-regulation of transforming growth factor (TGF)-β1, as disrupting TGF-β1 expression negated the benefits of ECH, suggesting its potential for improving intestinal health.
Cistanche deserticola has commonly been used in traditional Chinese medicine to treat many health problems including irritable bowel syndrome or constipation. This study was designed to test the efficacy of a water-extract of C. deserticola in the prevention of colorectal cancer in a mouse model.
