| characterization of putative membrane protein genes of the 'candidatus phytoplasma asteris', chrysanthemum yellows isolate. | to characterize potentially important surface-exposed proteins of the phytoplasma causing chrysanthemum yellows (cy), new primers were designed based on the conserved regions of 3 membrane protein genes of the completely sequenced onion yellows and aster yellows witches' broom phytoplasmas and were used to amplify cy dna. the cy genes secy, amp, and arti, encoding the protein translocase subunit secy, the antigenic membrane protein amp and the arginine transporter arti, respectively, were cloned ... | 2008 | 18449218 |
