提高多年生黑麦草（Lolium perenne，黑麦草）的磷养分利用率可能产生可观的经济效益和生态效益。到目前为止，对多年生黑麦草对缺磷的分子和生化反应的研究还很有限，特别是对早期反应机制的研究。本研究旨在确定在磷缺乏初期激活的分子机制。利用大麦芯片成功地研究了多年生黑麦草的基因表达，并辅以气相色谱-质谱代谢谱分析，以获得植物对早期缺磷反应的概述。缺磷24 h后，两种多年生黑麦草基因型体内磷浓度降低，代谢组和转录组发生显著变化。结果表明，多年生黑麦草对磷缺乏的反应是用亚脂替代磷脂和利用糖酵解旁路。24 h后，多年生黑麦草转录组和代谢组随着磷供应的减少而发生变化。
Improving phosphorus (P) nutrient efficiency in Lolium perenne (perennial ryegrass) is likely to result in considerable economic and ecological benefits. To date, research into the molecular and biochemical response of perennial ryegrass to P deficiency has been limited, particularly in relation to the early response mechanisms. This study aimed to identify molecular mechanisms activated in response to the initial stages of P deficiency. A barley microarray was successfully used to study gene expression in perennial ryegrass and this was complemented with gas chromatography-mass spectrometry metabolic profiling to obtain an overview of the plant response to early stages of P deficiency. After 24 h of P deficiency, internal phosphate concentrations were reduced and significant alterations were detected in the metabolome and transcriptome of two perennial ryegrass genotypes. Results indicated a replacement of phospholipids with sulfolipids and the utilization of glycolytic bypasses in response to P deficiency in perennial ryegrass. The transcriptome and metabolome of perennial ryegrass undergo changes in response to reductions in P supply after 24 h.
