Patterns and Mechanisms of Legume Responses to Nitrogen Enrichment: A Global Meta-Analysis

Plants, Journal Year: 2024, Volume and Issue: 13(22), P. 3244 - 3244

Published: Nov. 19, 2024

Nitrogen (N), while the most abundant element in atmosphere, is an essential soil nutrient that limits plant growth. Leguminous plants naturally possess ability to fix atmospheric nitrogen through symbiotic relationships with rhizobia their root nodules. However, widespread use of synthetic N fertilizers modern agriculture has led enrichment soils, causing complex and profound effects on legumes. Amid ongoing debates about how leguminous respond enrichment, present study compiles 2174 data points from 162 peer-reviewed articles analyze impacts underlying mechanisms The findings reveal significantly increases total legume biomass by 30.9% content tissues 13.2% globally. also leads notable reductions, including a 5.8% decrease root-to-shoot ratio, 21.2% decline nodule number, 29.3% reduction weight, 27.1% percentage derived

Phosphorus deficiency alters root length, acid phosphatase activity, organic acids, and metabolites in root exudates of soybean cultivars

Physiologia Plantarum, Journal Year: 2023, Volume and Issue: 175(6)

Published: Nov. 1, 2023

Abstract Phosphorus (P) deficiency alters the root morphological and physiological traits of plants. This study investigates how soybean cultivars with varying low‐P tolerance values respond to different P levels in hydroponic culture by assessing alterations length, acid phosphatase activity, organic exudation, metabolites exudates. Three low‐P‐tolerant (‘Maetsue,’ ‘Kurotome,’ ‘Fukuyutaka’) three low‐P‐sensitive (‘Ihhon,’ ‘Chizuka,’ ‘Komuta’) were grown under 0 (P0) 258 μM (P8) for 7 14 days after transplantation (DAT). Low‐P‐tolerant increased length 31% 119%, which was lower than 62% 144% increases sensitive P0 compared P8 at DAT, respectively. Acid activity exceeded that 5.2‐fold 2.0‐fold DAT. Root exudates from each cultivar revealed 177 metabolites, higher exudation P0. concentrations specific (oxalate, GABA, quinate, citrate, AMP, 4‐pyridoxate, CMP), distinguishing them The top five metabolomic pathways (purine metabolism, arginine proline TCA cycle, glyoxylate dicarboxylate alanine, aspartate, glutamate metabolism) more pronounced These findings indicate increasing not an adaptation strategy deficiency; instead, tolerant exhibit enhanced traits, including metabolite release, accelerated metabolic deficiency.

Legumes are highly nutritious in proteins and good food for humans animals because of their nutritional values. Plant growth-promoting bacteria (PGPR) microbes dwelling the rhizosphere soil a plant contributing to healthy status, growth promotion crops, preventing invasion diseases. Root exudates produced from leguminous plants’ roots can lure migrate region other carry out potential activities which reveals symbiotic association PGPR (rhizobia). To have better cognition plants, genomic analyses would be conducted employing various sequences observe microbial community functions soil. Comparative mechanism rhizobacteria was discussed this review including promotion, phosphate solubilization, production hormones, genes required development. Progress genomics improve collection genotyping data revealed review. Furthermore, also significance breeding involving transcriptomics bioeconomy promotion.

Enhancing photosynthetic phosphorus-use efficiency through coordination of leaf phosphorus fractions, allocation and anatomy during soybean domestication

Journal of Experimental Botany, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 13, 2024

Soybean domestication has significantly changed key agronomic traits, yet its impact on leaf photosynthetic phosphorus-use efficiency (PPUE) and underlying traits remain poorly known. Further information this would be important to increase soybean P-use efficiency. To address gap, 48 accessions (16 wild relatives, 16 landraces cultivars) were used compare anatomical foliar chemical P fractions, allocation PPUE under two levels. The results showed that the cultivars had higher area-based mass-based photosynthesis rates, PPUE, metabolite concentration, percentage of total P, as well a greater lipid nucleic acid residual P. Conversely, relatives tended have palisade:spongy thickness ratio, concentrations inorganic was negatively correlated with concentration relative while it positively We concluded increased result both rate decreased concentration; reduced ratio coupled P-containing metabolites, thereby contributing faster PPUE. This study shed light significance affecting during domestication, offering mechanistic understanding further enhance
