Differential activation of ABI3 and LEA genes upon plant parasitic nematode infection
Differential activation of ABI3 and LEA genes upon plant parasitic nematode infection
- Molecular Plant Pathology, 6(3), p.321-325, 2005 .
Promoter activity of ABI3 and of three LEA genes was monitored in Arabidopsis transgenics infected with Heterodera schachtii and Meloidogyne incognita . ABI3::GUS expression was induced (in four different promoter deletion constructs)during early infection stages with H. schachtii . Similar GUS expression patterns, though slightly later in time compared with ABI3 , were observed for one of the LEA promoter constructs, whereas the other two were not induced by H. schachtii . Expression was mainly observed in the syncytia. In contrast, little or no reporter gene expression was observed upon infection with M. incognita . The data suggest a role for ABI3 during the formation and active growth of the syncytium and demonstrate a marked difference between yncytium and giant cell ontogenesis.
