It was located immediately downstream from the thymidine kinase gene （TK）. In addition, the 3＇-end of the gene homologue to herpesvirus UL21 was located downstream from the gH gene. DPV gH gene open reading frame （ORF） was 2 505 bp in length and its primary translation product was a polypeptide of 834 amino acids long. It possessed several characteristics of membrane glycoproteins, including an N-terminal hydrophobic signal sequence, an external domain containing eight putative N-linked glycosylation sites, a C-terminal transmembrane domain, and a charged cytoplasmic tail. Comparison with other herpesvirus revealed identities of 20.2, 25.1, 23.0, 23.0, 26.5 and 26.0% with the gH counterparts of the human herpesvirus virus 1 （HSV1）, equine herpesvirus 4 （EHV4）, bovine herpesvirus 1 （BHV1）, pseudorabies virus （PRV）, gallid herpesvirus 2 （GHV2） and gallid herpesvirus 3 （GHV3）, respectively.展开更多

When Wenfeng7 was treated with 0.3%(W/V) NaCl for 3 d, the H +-ATPase activities in PM and TP from roots and leaves exhibited a reduction and an enhancement, respectively. The H +-PPase activity in TP from roots also increased. Similar effects were not observed in roots of Union. In addition, the increases of phospholipid content and ratios of phospholipid to galactolipid in PM and TP from roots and leaves of Wenfeng7 may also change membrane permeability and hence affect salt tolerance.展开更多
