Mannliche Wistar Ratten wurden intravenos mit 700 ×103 Sporozoiten von Plasmodium yoelii infiziert. Den Versuchstieren wurde 2 und 24 Stunden nach der Infektion 700 mg/kg eines Extraktes von chrysanthemum morifolium in die Bauchhohle gespritzt. 40 Stunden nach der Infektion wurden die Tiere getotet und in Leberdunnschnitten wurde die exoerythrozytare Schizogonie bestimmt. Es wurde gefunden, daβ zwar das Eindringen der Sporozoiten in die Leberzellen nicht gehemmt wurde,jedoch die intrazellulare Reifung zu infektiosen Formen der exoerythrozytare Schizogonie deutlich gehemmt war.

chrysanthemum WRKY gene CmWRKY17 negatively regulates salt stress tolerance in transgenic chrysanthemum and Arabidopsis plants

Chrysanthemum WRKY gene CmWRKY17 negatively regulates salt s...

江苏省遗传学会第九次会员代表大会暨学术研讨会

作者： Fadi Chen Peiling Li Aiping Song Chunyan Gao Linxiao Wang Yinjie Wang Jing Sun Jiafu Jiang Sumei Chen College of Horticulture Nanjing Agricultural University

WRKY transcription factors play regulatory roles as positive or negative regulators in response to various stresses in plants. In this study, CmWRKY17 was isolated from chrysanthemum（chrysanthemum morifolium）. The gene encodes a 227 amino acid protein and belongs to the group II WRKY family, but has an atypical WRKY domain with the sequence WKKYGEK. Our data indicated that CmWRKY17 was localized to the nucleus in onion epidermal cells and no transcriptional activity was detected in a yeast assay system. The expression of CmWRKY17 was induced by salinity in chrysanthemum, and a higher expression level was observed in the stem and leaf compared with the root, disc florets and ray florets. Overexpression of CmWRKY17 in chrysanthemum and Arabidopsis increased the sensitivity to salinity stress. The activities of superoxide dismutase and peroxidase and proline content in the leaf were significantly lower in transgenic chrysanthemum than those in the wild type under salinity stress, whereas electrical conductivity was increased in transgenic plants. Expression of the stress-related genes AtRD29, AtDREB2 B, AtSOS1, AtSOS2, AtSOS3, and AtNHX1 was reduced in the CmWRKY17 transgenic Arabidopsis compared with that in the wild-type Col-0. Collectively, these data suggest that CmWRKY17 may increase the salinity sensitivity in plants.
