Summary: This study investigated the response of Eucalyptus clones to aluminum toxicity, with findings showing that the aluminum-tolerant clone G9 exhibited earlier and greater secretion of organic acids compared to the aluminum-sensitive clone W4. Enhanced activities of enzymes involved in organic acid metabolism were associated with the increased secretion of citrate in G9, contributing to aluminum detoxification.

Summary: It is known that plant-growth-promoting rhizobacteria (PGPRs) can increase plant tolerance to abiotic stresses, but little is known about their effects on counteracting aluminum toxicity. This study investigated the effects of specially selected Al-tolerant and Al-immobilizing microorganisms on pea cultivars under aluminum stress. The strain Cupriavidus sp. D39 was the most efficient in promoting pea growth under aluminum stress, increasing plant biomass by 20% and 2 times in the two cultivars. This strain immobilized aluminum in the nutrient solution and decreased its concentration in the Al-sensitive mutant roots.

Summary: This study aimed to investigate the variation in root morphology and Cd accumulations under moderate Cd stress among diverse maize genotypes. The results showed significant genotypic variation in the response to Cd toxicity, with Cd-tolerant genotypes optimizing root morphology and Cd accumulation and distribution.

Summary: White lupin forms cluster roots under phosphorus deficiency to mobilize soil phosphates, with citrate released through MATE/DTX proteins. LaMATE and LaMATE3 are candidate genes for citrate release in mature clusters, inducing inward-rectifying currents when expressed in oocytes.

Summary: The study identified a novel role of glycine in regulating kidney calcium oxalate crystal formation, showing that glycine can attenuate CaOx crystal deposition by decreasing urine oxalate and increasing urine citrate levels. The mechanism involves downregulating Slc26a6 expression to decrease urine oxalate and inhibiting Nadc1 expression to increase urine citrate, with additional regulation of protein expression by miRNA-411-3p. These findings provide a potential target for the treatment of kidney calcium oxalate stones.

Summary: The research found different risks and important variables in urinary stone development between prepubertal and pubertal/postpubertal children, with citrate and glycosaminoglycans increasingly important in children. J48 classifier confirmed the importance of certain variables for distinguishing between children with urolithiasis and healthy children of the same age and gender.

Summary: Aluminum toxicity in acid soils affects plant development and yield. Citrate plays a crucial role in plant defense against aluminum toxicity. This study identifies the mitochondrial citrate synthase gene as being repressed under aluminum stress in both rye and Brachypodium distachyon, with higher mRNA levels observed in aluminum-tolerant lines.

Summary: Iron toxicity in rice leads to reduced yields due to excessive uptake of ferrous iron, which is more soluble in paddy soils. Different tolerance mechanisms, such as reduced uptake and compartmentalization, play different roles at different growth stages. Screening protocols need to capture the individual tolerance mechanisms, considering the effects of growth stage, mineral nutrition, and possible interactions with other factors.

Summary: The study found that common buckwheat has high tolerance to lead but low tolerance to cadmium, with plants in organic acidic soil being the most vulnerable to cadmium toxicity. The results also indicate a generally low tolerance of buckwheat to cadmium, except for in organic neutral soil.

Summary: This study investigated the effects of water stress on cocoa trees and found that they are highly sensitive to water stress, with different genotypes exhibiting varied responses. Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.

Summary: In this study, the effects of potassium citrate and chlorthalidone on calcium oxalate stone formation and bone quality were investigated using a genetic hypercalciuric stone-forming rat model. The results showed that potassium citrate plus chlorthalidone combination was more effective in reducing stone formation, while chlorthalidone alone improved bone quality.

Summary: Aluminum toxicity is a significant production constraint for common bean. A genome-wide association study identified genotypes with superior seedling Al resistance and detected genomic regions associated with Al resistance in the Andean gene pool. Major single nucleotide polymorphisms on chromosomes Pv01, Pv02, Pv03, Pv05, Pv06, and Pv10 were significantly linked to Al resistance, with the most significant SNP on Pv02 explaining 21.1% of phenotypic variation.

Summary: This study demonstrates that altering the composition of root exudates can significantly change the root microbiome composition throughout the root system, but the root type, position along the roots, and soil type have a greater influence on microbiome structure than the exudates.
