Research Progress in Crop Root Biology and Nitrogen Uptake and Use, with Emphasis on Cereal Crops

Agronomy, Journal Year: 2023, Volume and Issue: 13(7), P. 1678 - 1678

Published: June 22, 2023

The biological characteristics of crop roots are closely related to the efficient utilization nitrogen and have become a research hotspot in agricultural cultivation breeding recent years. root system microbiota play crucial role both basic plastic growth development plants response external environmental changes. Nitrogen is an indispensable nutrient element for growth, key achieving high yield quality crops establishing environmentally friendly production. absorbed utilized by rice mainly enters aboveground part plant through from within soil. This process explored perspective biology (root morphology, physiological biochemical characteristics, regulation, rhizosphere microorganisms, their symbiotic systems), which line with directions “less investment, increased production, protection, sustainable development” China. Based on status this field at present, article interaction mechanism between absorption utilization, looks forward future biology. study provides theoretical basis reducing fertilizer application, optimizing nitrogen-efficient management techniques, selecting varieties.

Soil quality and yield attributes of soybean on an Ultisol conditioned using cogongrass biochar enriched with nitrogen fertilizer dissolved in seaweed extract

Journal of Degraded and Mining Lands Management, Journal Year: 2025, Volume and Issue: 12(2), P. 7353 - 7368

Published: Jan. 1, 2025

The soil quality of Ultisol, which is indicated by its chemical properties, arbuscular mycorrhizal fungi (AMF), and root nodules, important for soybean growth. Cogongrass biochar enriched with N fertilizer solution using solvent from seaweed extract can change the quality. Using various solvents, this study sought to (i) test impact cogongrass on (ii) examine effects changes AMF, tissue nutrient content, yield. treatments consisted without (B0), enrichment (BN0), (iii) urea Kappapychus alvarezii (BNK), (iv) Sargassum sp. (BNS), (v) Ulva lactuca (BNU). In a randomized block design, each treatment was carried out three times. With or fertilization, improves fertility soil. increase in NH4+-N nitrate-N content greater than unenriched. AMF spores density nodules were reduced following enrichment. When added, there more pods, pod dry weight, total seeds, regular seeds per plant. conclusion, increasing ammonium led decreased spores, infections, nodules. level available P greatly affected components yield Ultisol.

Combined Analysis of the Leaf Metabolome, Lipidome, and Candidate Gene Function: Insights into Genotypic Variation in Phosphorus Utilization Efficiency in Stylosanthes guianensis

Journal of Agricultural and Food Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 17, 2025

Stylo (Stylosanthes guianensis) exhibits excellent tolerance to low-phosphate (Pi) availability, but the underlying mechanisms responsible for improving phosphorus (P) utilization efficiency (PUE) remain unclear. This study employed metabolomics, lipidomics, and gene expression analyses investigate differential responses low-Pi stress between high-PUE genotype CF047827 cultivar Reyan No. 2. Results showed that had higher levels of membrane lipid remodeling-related genes in its leaves compared 2 under conditions. was accompanied by greater phospholipid degradation non-P-containing biosynthesis CF047827. Furthermore, purple acid phosphatase SgPAP27a, which is more highly expressed than conditions, identified functionally characterized. Its role promoting enhancing PUE confirmed through heterologous Arabidopsis. These findings provide insights identify potential candidate breeding crop cultivars.

Identification of Candidate Genes Controlling Red Seed Coat Color in Cowpea (Vigna unguiculata [L.] Walp)

Horticulturae, Journal Year: 2024, Volume and Issue: 10(2), P. 161 - 161

Published: Feb. 9, 2024

Seed coat color is an important consumer-related trait of the cowpea (Vigna unguiculata [L.] Walp.) and has been a subject study for over century. Utilizing newly available resources, including mapping populations, high-density genotyping platform, several genome assemblies, red seed mapped to two loci, Red-1 (R-1) Red-2 (R-2), on Vu03 Vu07, respectively. A gene model (Vigun03g118700) encoding dihydroflavonol 4-reductase, homolog anthocyanidin reductase 1, which catalyzes biosynthesis epicatechin from cyanidin, identified as candidate R-1. Possible causative variants have also Vigun03g118700. Vu07 (Vigun07g118500), with predicted nucleolar function high relative expression in developing seed, R-2. The observed believed be result buildup cyanidins coat.
