Potassium (K) is one of the most important mineral nutrients required for fruit growth and development and is known as a 'quality element'. To investigate the role of K in more detail, we performed experiments in which seven-year-old pot-grown 'Huangguan' pear trees were treated with three levels of K (0, 0.4, or 0.8 g K2O kg-1 soil). K supply improved the development of vascular bundles in pear petioles and fruit peduncles and enhanced expression of genes involved in nutrients and sugar… Expand

Advances in Mineral Nutrition Transport and Signal Transduction in Rosaceae Fruit Quality and Postharvest Storage
Mineral nutrition, taken up from the soil or foliar sprayed, plays fundamental roles in plant growth and development. Among of at least 14 mineral elements, the macronutrients nitrogen (N), potassiumExpand
Mineral elements uptake and physiological response of Amaranthus mangostanus (L.) as affected by biochar.
TLDR
Results showed that biochar could significantly alter the mineral migration in amaranth and physiologically damage in the plants, and it is essential to study the effect of biochar within appropriate concentrations on plants prior to wide application in agriculture. Expand
Synergistic and antagonistic interactions between potassium and magnesium in higher plants
TLDR
The antagonistic effect of K on Mg is stronger than that of Mg on K in root absorption and transport within plants, indicating that the balanced use of K and Mg fertilizers is necessary for sustaining high plant-available Mg and alleviating K-induced Mg deficiency, especially in plant species with high K demand or in high-available-K soil.

Spatio-temporally expressed sorbitol transporters cooperatively regulate sorbitol accumulation in pear fruit.
TLDR
Interestingly, it is found that sorbitol accumulation in pear fruit was cooperatively mediated by SOT3, SOT6/20, Sot19/21, and SOT22, which provides a foundation for further research into sugar accumulation processes in pear Fruit, contributing to the improvement of fruit quality. Expand

Alteration of nutrient allocation and transporter genes expression in rice under N, P, K, and Mg deficiencies
TLDR
Findings suggest that deficiencies of the major nutrients suppressed the export of carbohydrates from source leaves and regulated sugar and nutrient transporter genes investigated in this study could be used for elucidating the molecular mechanism of plants in their adaptation to varied nutrient supply.

Potassium Application Reduces Calcium and Magnesium Levels in Bermudagrass Leaf Tissue and Soil
TLDR
High K rates appear to increase the potential for Ca and Mg deficiencies in bermudagrass, indicating that rates higher than those that provide suffi- cient K levels for normal growth should not be used. Expand
Comparative transcriptome profiling of potassium starvation responsiveness in two contrasting watermelon genotypes
TLDR
It is suggested that repressed defense and stress response can save energy for better root growth in YS, which can facilitate K+ uptake and increase K efficiency and tolerance to K+ deficiency. Expand
Effect of potassium application on celery growth and cation uptake under different calcium and magnesium levels in substrate culture
Abstract The effect of potassium (K) on celery (Apium graveolens L.) growth and cation uptake was studied under different calcium (Ca) and magnesium (Mg) levels in substrate culture in theExpand
Multilevel Analysis of Primary Metabolism Provides New Insights into the Role of Potassium Nutrition for Glycolysis and Nitrogen Assimilation in Arabidopsis Roots1[W][OA]
TLDR
regulation of enzymes at the level of transcripts and proteins is likely to play an important role in plant adaptation to K deficiency by maintaining carbon flux into amino acids and proteins, decreasing negative metabolic charge, and increasing the nitrogen-carbon ratio in amino acids. Expand
Transcriptome Analysis of Differentially Expressed Genes Induced by Low and High Potassium Levels Provides Insight into Fruit Sugar Metabolism of Pear
TLDR
The gene expression patterns of leaves and fruit in response to different K levels during the middle and late stages of fruit development as well as the molecular mechanism of improvement of fruit sugar levels by K were revealed and provided a scientific basis for improving fruit quality with supplemental K fertilizers.

Potassium nutrition and translocation in sugar beet.
TLDR
It is suggested that K(+)-promoted increase in synthetic metabolism may be the basis of the increased carbon assimilation and translocation in plants supplied with an above-minimal level of K(+). Expand
Relationship between xylem functionality, calcium content and the incidence of bitter pit in apple fruit
TLDR
The large loss in xylem functionality in ‘Catarina’ apples which led to a higher (K + Mg +-N)/Ca ratio in the fruit seems to explain the higher susceptibility to BP as compared to ‘Fuji’. Expand
Growth and cation absorption of some fruit‐vegetable crops grown on rockwool as affected by different cation ratios in the nutrient solution

Magnesium deficiency in sugar beets alters sugar partitioning and phloem loading in young mature leaves
TLDR
The observed increase in BvSUT1 gene expression supports the idea that sucrose loading into the phloem is defective, resulting in its accumulation in the leaf, and helps identify how Mg deficiency alters carbon partitioning in sugar beet (Beta vulgaris L.) plants. Expand
