Between the two major rice subspecies, indica varieties generally exhibit higher nitrate (NO3‒) uptake and nitrogen (N)-use efficiency (NUE) than japonica varieties. Introducing efficient NO3‒ utilization alleles from into could improve NUE, at same time uncover unknown regulators of metabolism. Here, we identify OsWRKY23 as a key regulator NUE differences between rice. The OsWRKY23indica allele exhibits reduced transcriptional activation negative auxin accumulation, DULL NITROGEN RESPONSE1 (DNR1). resultant increase in level improves assimilation, which ultimately enhances grain yield. Geographical evolutionary analyses reveal overlapping distribution DNR1indica, particularly low-fertility soils, suggesting their involvement adaptation to low N conditions Incorporating OsWRKY23-DNR1 module represents promising strategy enhance is crucial for sustainable agriculture. Rice have use that authors show natural variation its interaction with (DNR1)-mediated accumulation play role divergence subspecies.

Summary Arbuscular mycorrhizal (AM) fungi play a crucial role in the nitrogen uptake and Verticillium wilt resistance of cotton. The absorbed inorganic is converted into organic through assimilation mediated by glutamine synthetase (GS). However, GS AM symbiosis remains unclear. We identified an fungus‐induced gene, GhGLN1.5 , which participated symbiosis. Both vivo vitro analyses demonstrated that exhibits catalytic activity GS. knockdown resulted reduction colonization, capacity, symbiosis‐dependent to wilt. Heterologous expression enhanced symbiosis, increased activity, promoted plant growth. knockout cotton inhibited Furthermore, we ethylene response factor gene GhWRI3 yeast one‐hybrid library screening found activates via AW‐box element. These findings provide valuable insights molecular mechanisms assimilation, cotton, suggesting potential strategies for regulating WRI3 – GLN1.5 module.

Summary Differences in soil mobility and assimilation costs between organic inorganic nitrogen (N) compounds would hypothetically induce plant phenotypic plasticity to optimize acquisition of, performance on, the different N forms. Here we evaluated this hypothesis experimentally theoretically. We grew Arabidopsis split‐root setups combined with stable isotope labelling study uptake distribution of carbon (C) from l ‐glutamine ( ‐gln) NO 3 − assessed effect source on biomass partitioning use efficiency (CUE). Analyses isotopes showed that 40–48% C acquired ‐gln resided plants, contributing 7–8% total both shoots roots. Plants grown exhibited increased root mass fraction hair length a significantly lower rate per unit but displayed enhanced CUE. Our data suggests nutrition is linked particular phenotype extensive growth roots hairs optimizes for less mobile Increased CUE may be key facets phenotype.

Post-harvest storage loss in sugar beets due to root rot and respiration can cause >20% loss. Breeding strategies focused on factors contributing improved post-harvest quality are of great importance prevent losses. Using 16S rRNA ITS sequencing beet mutational breeding lines with high disease resistance (R), along a susceptible (S) commercial cultivar, the role microbiome metabolome performance was investigated. The R general showed higher abundances bacterial phyla, Patescibacteria at M time point, Cyanobacteria Desulfobacterota L point. Amongst fungal Basidiomycota (including Athelia) Ascomycota were predominant diseased samples. Linear discriminant analysis Effect Size (LEfSe) identified taxa such as Micrococcales, Micrococcaceae, Bacilli, Glutamicibacter, Nesterenkonia, Paenarthrobacter putative biomarkers associated lines. Further functional enrichment abundance bacteria, those related super pathway pyrimidine deoxyribonucleoside degradation, L-tryptophan biosynthesis L, fungi, L-iditol 2-dehydrogenase Metabolome roots revealed pathways arginine, proline, alanine, aspartate, glutamate metabolism M, addition beta-alanine butanoate Correlation between metabolites indicated that root’s biochemical composition, presence nitrogen-containing secondary metabolites, may regulate relative key microbial candidates better storage.

Abstract BACKGROUND Bacterial fruit blotch (BFB), known as the ‘cancer’ of cucurbits, is a seed‐borne disease melons caused by Acidovorax citrulli . Traditional chemical treatments for BFB are ineffective and adversely affect environment. Using dielectric barrier discharge (DBD) nanosecond‐pulsed plasma technology, melon seeds were treated to promote germination growth control BFB. RESULTS Based on evaluation parameters seed germination, seedling growth, leaf yellowing bacterial infection after treatments, 9 min at 20 kV was selected optimal parameter. In this study, significantly improved treating carrying A. using The number first true leaves measured eighth day 2.3 times higher index reduced 60.5% compared group. Attenuated total reflectance–Fourier transform infrared measurements show that penetrate coat denature polysaccharides proteins in kernel, affecting their sterilization properties. CONCLUSION Pre‐sowing treatment technology can effectively optimizing DBD parameters. © 2024 Society Chemical Industry.
