Multi-omics-based identification of purple acid phosphatases and metabolites involved in phosphorus recycling in stylo root exudates

International Journal of Biological Macromolecules, Journal Year: 2023, Volume and Issue: 241, P. 124569 - 124569

Stylo (Stylosanthes guianensis) is a tropical forage and cover crop that possesses low phosphate (Pi) tolerance traits. However, the mechanisms underlying its to low-Pi stress, particularly role of root exudates, remain unclear. This study employed an integrated approach using physiological, biochemical, multi-omics, gene function analyses investigate stylo exudates in response stress. Widely targeted metabolomic analysis revealed eight organic acids one amino acid (L-cysteine) were significantly increased Pi-deficient seedlings, among which tartaric L-cysteine had strong abilities dissolve insoluble-P. Furthermore, flavonoid-targeted identified 18 flavonoids under conditions, mainly belonging isoflavonoid flavanone subclasses. Additionally, transcriptomic 15 genes encoding purple phosphatases (PAPs) upregulated expression roots conditions. Among them, SgPAP10 was characterized as root-secreted phosphatase, overexpression enhanced organic-P utilization by transgenic Arabidopsis. Overall, these findings provide detailed information regarding importance adaptation highlighting plant's ability release Pi from insoluble-P sources through acids, flavonoids, PAPs.

Enhancement of rice traits for the maintenance of the phosphorus balance between rice plants and the soil

Current Plant Biology, Journal Year: 2024, Volume and Issue: 38, P. 100332 - 100332

Phosphorus (P) is essential for maximizing crop yield, yet many areas dedicated to rice cultivation suffer from a scarcity of plant-accessible inorganic phosphate (Pi) due its fixation in the soil. Conversely, regions with ample P fertilization often resort excessive application compensate deficiencies, resulting adverse environmental impacts. While significant strides have been made understanding molecular mechanisms governing uptake capacity (PUP/PAE) and use efficiency (PUE) rice, their practical implementation breeding impeded by absence robust, high throughput phenomics techniques, leading inconsistencies gene/quantitative trait loci (QTL) effects. This review underscores necessity comprehensive Pi transporters, internal remobilization, root morphology modifications under deficiency, correlating these traits specific phenotypic markers. Developing precise, cost-effective, high-throughput phenotyping techniques imperative creating ideotypes enhanced PAE/PUE. Additionally, we explore potential meta-QTL analysis prioritizing genomic related PUE, utilizing "meta-genome" encompassing diverse reference genomes. We also delve into development phosphite (Phi)-tolerant aiming reduce dependence on fertilizers create herbicide-resistant through Phi-based fertilization. Finally, discuss utilization arbuscular mycorrhizal fungi (AMF) enhance rice.
