A loose endosperm structure of wheat seed produced under low nitrogen level promotes early germination by accelerating water uptake.

摘要: Water uptake is the fundamental requirement for initiation and completion of seed germination that a vital phase in life cycle plants. We found seeds produced under four nitrogen levels showed significantly different speed. The objective this study was to mechanism rapid explore which pathways genes play critical roles radicle protrusion. Anatomical data revealed protein content affected endosperm structure seeds. Moreover, scanning electron microscope maps faster germinated had looser compared with other Subsequently, high throughout RNA-seq were used compare transcriptomes imbibed Gene ontology (GO) term enrichment analysis cell wall metabolism related up-regulated In these genes, top chitinase about fourfold higher expression Kyoto Encyclopedia Genes Genomes (KEGG) enhanced glutathione metabolism. By combining results, we propose model fertilizer affects speed wheat seed, provide new insights into germination.
