This knowledge is essential for the biofortification of wheat with Zn. <em>Methods</em>: We analyzed Zn rhizo–mobilization, root morphology, Zn uptake, and the microbial composition in the rhizosphere and roots of four high–yielding wheat cultivars with contrasting grain Zn levels. The study was conducted under two P fertilizer rates, 0 and 44 kg P/ha, on the southern Loess Plateau, China. <em>Results</em>: Bacteria potentially alleviating P–Zn antagonisms, such as <em>Rhizobium</em> sp., <em>Sphingomonas</em> sp., and <em>Pseudomonas</em> spp., were specially enriched in H<sub>Zn</sub> cultivars with P application and demonstrated the ability to promote Zn rhizo–mobilization by decreasing soil pH, resulting in a 69.1 % increase in available Zn concentration. P application reduced root colonization by AM fungi <em>Diversispora densissima</em> in Low–Zn (L<sub>Zn</sub>) cultivars but not in H<sub>Zn</sub> cultivars, allowing H<sub>Zn</sub> cultivars to maintain higher root Zn acquisition efficiency. The P–induced increases in total root length and surface area per plant in H<sub>Zn</sub> cultivars were 40 % and 7 % higher, respectively, compared to L<sub>Zn</sub> cultivars, while the increase in average root diameter of H<sub>Zn</sub> cultivars was 62 % lower than that of L<sub>Zn</sub> cultivars. This suggests that the longer, thinner roots with larger surface areas were advantageous for H<sub>Zn</sub> cultivars in capturing more Zn from the soil. <em>Conclusion</em>: Therefore, recruiting more beneficial rhizobacteria, maintaining stable root colonization by AM fungi, and optimizing root growth are crucial strategies for H<sub>Zn</sub> cultivars to enhance shoot Zn uptake and mitigate P–Zn antagonism. <em>Implications or significance</em>: Combining high–Zn wheat with specific bacteria and fungi at the soil–root interface, along with appropriate P application, holds significant potential for achieving wheat biofortification with Zn.</div></div>","PeriodicalId":12143,"journal":{"name":"Field Crops Research","volume":"322 ","pages":"Article 109762"},"PeriodicalIF":5.6,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, an increased N application rate reduces N use efficiency (NUE), and a higher planting density elevates the risk of lodging, thus limiting production benefits. Dwarf and compact rapeseed varieties exhibit high lodging resistance but possess low yield potential, while cultivars with conventional plant architecture possess high yield potential but are susceptible to collapse under dense planting. Limited research exists on utilizing the advantages of materials with different plant architectures to enhance N utilization and yield in rapeseed.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;The experiment was conducted using the dwarf mutant HS5sca, the tall wild-type HS5, and their F1 semi-dwarf and compact hybrid HS5&lt;sub&gt;&lt;em&gt;+/sca&lt;/em&gt;&lt;/sub&gt; all sharing the same genetic background from 2019 to 2022. The field experiment used a split-split-plot design with three different planting densities (D1, D2, and D3: 15 × 10⁴, 45 × 10⁴, and 75 × 10⁴ plants ha⁻¹) and three different N application rates (N1, N2, and N3: 120, 240, and 360 kg ha⁻¹) to find out how N application rate and planting density affected NUE and yield in different genotypes.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;With increasing N rate and planting density, the expression levels of nitrate transporter-encoding genes, &lt;em&gt;BnaC08.NPF6.3&lt;/em&gt; and &lt;em&gt;BnaA07.NPF4.6&lt;/em&gt;, in roots increased first and then decreased in HS5&lt;sub&gt;&lt;em&gt;sca&lt;/em&gt;&lt;/sub&gt; and HS5&lt;sub&gt;&lt;em&gt;+/sca&lt;/em&gt;&lt;/sub&gt;, reaching the peak at N2 and D2, respectively, while in HS5 they increased with increasing N rate and increased first and then decreased with increasing planting density. Meanwhile, the activities of nitrate reductase, nitrite reductase, glutamine synthetase, and glutamate synthase in roots of the three genotypes at the flowering stage increased with increasing N rate, while these enzyme activities increased first and then decreased with increasing planting density. These enzyme activities increased N and dry matter accumulation in both roots and shoots, as well as a higher N contribution rate (NCR). Despite declines in agronomic NUE (aNUE) and the partial factor productivity of N (PFPN) with increasing N rate, the relative growth rates of root and shoot increased, positively affecting yields under most of the treatments. Conversely, NCR and aNUE decreased, while root and shoot N, dry matter accumulation, PFPN and, yield initially increased and then decreased with increasing planting density. Compared with N1, the average yield over three years for HS5&lt;sub&gt;&lt;em&gt;sca&lt;/em&gt;&lt;/sub&gt;, HS5&lt;sub&gt;&lt;em&gt;+/sca&lt;/em&gt;&lt;/sub&gt;, and HS5 increased by 24.5 %, 22.1 %, and 14.6 % at N2, and 8.1 %, 10.2 %, and 4.6 % under D2 compared to D1, respectively.
