Under greenhouse conditions, incorporating ground straw in the soil at rates between 2,240 and 8,970 kg/ha reduced the emergence of alfalfa (Medicago media Pers. cv. Beaver) significantly (P < 0.05) and bromegrass (Bromus inermis Leyss cv. Magna) slightly, but had no effect on barley (Hordeum vulgare L. cv. Conquest). Rape (Brassica napus L. cv. Target and B. campestris L. cv. Echo) straws were more damaging than wheat (Triticum aestivum L. cv. Manitou) straw. Symptoms of severe nitrogen deficiency appeared early in the growth of barley where straw had been added to the soil. The effect on tillering varied. In one experiment tillers were smaller, in one tillers were larger; but in both, total leaf area produced was much less where 8,970 kg/ha of straw had been added to the soil. Bromegrass showed the same effects but to a lesser degree, probably because of slower growth requiring a smaller supply of nitrogen. Alfalfa growth was apparently unaffected. There was no evidence that the straw of either rapeseed species was more deleterious than wheat straw to crop growth after emergence. It is concluded that straw incorporated in soil affected barley and bromegrass growth by reducing the availability of nitrogen.

The development of crop cultivars with high nitrogen use efficiency (NUE) under low-N fertilizer inputs is imperative for sustainable agriculture. However, there has been little research on the molecular mechanisms underlying enhanced resilience to low N in high-NUE plants. The comparison of the transcriptional responses of genotypes contrasting for NUE will facilitate an understanding of the key molecular mechanism of wheat resilience to low-N stress. In the current study, the RNA sequencing (RNA-seq) technique was employed to investigate the genotypic difference in response to N deficiency between two wheat NILs (1Y, high-NUE, and 1W, low-NUE). In our research, high- and low-NUE wheat NILs showed different patterns of gene expression under N-deficient conditions, and these N-responsive genes were classified into two major classes, including “frontloaded genes” and “relatively upregulated genes”. In total, 103 and 45 genes were identified as frontloaded genes in high-NUE and low-NUE wheat, respectively. In summary, our study might provide potential directions for further understanding the molecular mechanism of high-NUE genotypes adapting to low-N stress.
