Genome-wide association analysis (GWAS) was performed on the relative hypocotyl length (RHL) using the 140 B. napus genotyped under zinc stress treatment (30 mg L  1 ) at germination stage by Illumina 60K SNP array, and then significant SNP locus and candidate genes were detected. In the study, the population structure analysis revealed that the 140 B. napus were classified into two subgroups, and the kinship coefficients of the 89% materials were less than 0.1, indicating the tested population had a distant relationship. GWAS analysis indicated that there were significantly 8 SNP locus correlated RNA-Seq. GO enrichment analysis indicated that the up-regulated genes mainly participated in redox reaction, ion transport, stress response, defense response and sulfur compound transport. Nineteen candidate genes response to zinc stress were identified by GWAS analysis and RNA-seq, including the genes encoding zinc finger protein (B-box type and ZFP1), glutathione transferase GSTU21, peroxidase family protein, ABC and MFS transporters, cell wall-related kinase protein, and genes encoding transcription factors (TF), such as BnaA07g27330D (MYB), BnaA02g30270D (bHLH), BnaA07g27840D (WRKY57), BnaA07g31860D (ORA47), and BnaA07g28000 (NAC).

Experiments 1 and 2 were conducted in two fields with varied soil fertility and consistent treatment. Two rice varieties (Dexiang 4103, high NUE; Yixiang 3724, low NUE) were set as main plot. The sub-plot contained six nitrogen-water management modes (farmer’s usual management, FU; nitrogen-water coupling management, NWC; methodical nitrogen-water distribution management, MNWD; and their respective nitrogen-free controls). The main plot of Exp.3 was two high NUE varieties (Dexiang 4103, Fyou 498) and two low NUE varieties (Yixiang 3724, Chuanyou 6203); FU, NWC, and MNWD assembled the sub-plot. MNWD adopted the method of increasing frequency and re-ducing quantity, thus the nitrogen application rate was reduced by 20% compared with NWC and FU, the irrigation water amount was reduced by 20% to 25% compared with NWC, and smoothly and its ear bearing tiller percentage was higher. Compared with NWC and FU, the photo assimilation before anthesis MNWD had less, dry matter transportation before anthesis and high accumulation of assimilate after anthesis. The grain yield of MNWD was similar to that of NWC, while 8.77%–14.18% higher than that of FU. Correlation analysis showed that the dry weight of roots in 10–20 cm and 20–30 cm soil layers were significantly and positively correlated with nitrogen recovery efficiency (NRE), nitrogen agronomy efficiency (NAE), irrigation water production efficiency (IWPE) and water production efficiency (WPE). MNWD had a large amount of root system distributed in the soil layer below 10 cm, which was conducive to the improvement of water and nitrogen utilization efficiency.

Sequence analysis showed that ARC1 consisted of 663 amino acids in <em>B. oleracea</em> and 661 amino acids in <em>B. napus</em>, with a 45-amino-acid difference between them.

The homology between EXO70A1 alleles was higher than that between ARC1 alleles.

However, there was very weak interaction between EXO70A1 and a 316-C-terminal-deletion mutant of ARC1 (ARC1_N), which only activated the expressions from 3 reporter genes (<em>ADE2</em>, <em>AUR1-C</em>, and <em>MEL1</em>).
