Comparative Proteome Profiles of Polygonatum cyrtonema Hua Rhizomes (Rhizoma Ploygonati) in Response to Different Levels of Cadmium Stress

ABSTRACT: The Polygonatum cyrtonema Hua rhizomes (Rhizoma Polygonati, RP) are consumed for health benefits. The main source of the RP is wild P. cyrtonema populations in the Hunan province of China. However, the soil Cadmium (Cd) content in Huanan is increasing, thus increasing the risks of Cd accumulation in RP and ending up in the human food chain. We subjected different levels of Cd stress to study the protein regulation mechanism under cadmium stress of P. cyrtonema.

<h4>Background</h4>The Polygonatum cyrtonema Hua rhizomes (also known as Rhizoma Polygonati, RP) are consumed for their health benefits. The main source of the RP is wild P. cyrtonema populations in the Hunan province of China. However, the soil Cadmium (Cd) content in Huanan is increasing, thus increasing the risks of Cd accumulation in RP which may end up in the human food chain. To understand the mechanism of Cd accumulation and resistance in P. cyrtonema, we subjected P. cyrtonema plants to ...[more]

Project description:Phytoremediation soil polluted by heavy metal has been drawn on a worldwide attention from human society. However, how to improve the efficiency of plant remediation of soil contaminated by cadmium remains unknown. Previous studies showed that nitrogen (N) significantly enhanced cadmium uptake in poplar plants. In order to further explore the key role of N in the detoxification against cadmium stress in plants, this study try to investigate the poplar proteome and phosphoproteome difference between Cd stress and Cd+N treatment. In total, 5838 of the 6573 identified were quantified. With a fold-change threshold >1.3 and p-value<0.05, 375 and 108 proteins were up- and down-regulated by Cd stress when compared to the control, 42 and 89 proteins were up- and down-regulated, respectively, in Cd+N / Cd group, 522 and 127 proteins were up- and down-regulated, respectively, in Cd+N / CK group. In addition, the phosphoproteome data was obtained after the proteomic difference was normalized, and 1471phosphosites in 721 proteins were quantified. Based on a fold-change threshold >1.2, P-value <0.05, the Cd stress up-regulated 8 phosphosites in 8 proteins and down-regulated 69 phosphosites in 58 proteins, whereas N+Cd treatment up-regulated 95 phosphosites in 86 proteins and down-regulated 17 phosphosites in 17 proteins when compared to sole Cd stress. In addition, N+Cd treatment up-regulated 74 phosphosites in 60 proteins and down-regulated 42 phosphosites in 37 proteins when compared to the control.Several putative responses to stress proteins, transcriptional and translational regulation factors were up-regulated by addition ofexogenous nitrogen followed Cd stress at the proteome and phosphoproteome levels. Especially, heat shock protein 70 (HSP70), peroxidase (POD), zinc finger protein (ZFP), ABC transporter protein (ABC), eukaryotic translation initiation factor (elF) and splicing factor 3B subunit 1-like (SF3BI) were up-regulated by Cd+N treatment whether at the proteome or at the phosphoproteome levels, which was need to further study. In a word, taken together of proteome and phosphoproteome data, nitrogen serves a protective role in plants treated with Cd by multiple ways.
