Plant Resistance Genes in Poplar (//Populus// spp.) against //Xanthomonas// Infection

Author: Noemi Casarin
Internal reviewer: Pavel Beran
Expert reviewer: WANTED!

Pathogen: //Xanthomonas populi// pv. //populi//

Resistance synthetic gene: //D4E1//

Synonyms

NA

Source

Transgenic hybrid poplar Populus tremula L. x Populus alba L., line Tr23 (Mentag et al., 2003).

Status (identified, mapped, cloned, sequenced)

Cloned in the plasmid pBI-d35S-D4E1-nos (Cary et al., 2000) and in the plasmid ubi7-D4E1 (Mentag et al., 2003).

Molecular markers

  • PCR analysis of genomic DNA with specific primers to verify that the ubi7-D4E1-nos expression cassette is present in the plant genome of transgenic poplar clones (Mentag et al., 2003);
  • Expression of D4E1 tested by RT-PCR and RNA dot-blot analysis (Mentag et al., 2003).

Brief description

A synthetic gene coding for D4E1 (Cary et al., 2000), which is a synthetic antimicrobial peptide consisting of 17 amino acid residues (Demeter BioTechnologies, Ltd.) (De Lucca et al., 1998). Mentag et al. (2003) observed reduced symptoms on one D4E1-transgenic poplar line (Tr23) in response to X. populi pv. populi two months after its inoculation compared with control plants (Figure 1). These reduced symptoms correlated with the presence of large amount of the D4E1 transcript in Tr23 (Mentag et al., 2003).


Pathogen elicitors

  • Crude elicitors from X. campestris pv. campestris strain 147
  • Crude elicitors from X. populi pv. populi strain 2551

Genes involved in defense

MAPK genes (Hamel et al., 2005; Duplessis et al., 2009).

Synonyms

NA

Source

Hybrid poplar cell suspension cultures of Populus trichocarpa x Populus deltoides H11-11 (Dr. M. Gordon, University of Washington, Seattle, WA) (Hamel et al., 2005).

Status (identified, mapped, cloned, sequenced)

NA

Molecular markers

Expression of MAPK genes tested by in-gel kinase assay (Hamel et al., 2005).

Brief description

Perception of a mix of various elicitors from both bacterial strains (which can be quite specific but for which the specific poplar R-genes for Xanthomonas spp. are unknown) activated two MAPKs of about 44 and 47 kD, probably of ERK-type. The MAPKs are then activating plant defense mechanisms (Hamel et al., 2005).


Resistance gene: Unknown

Synonyms

  • P. nigra: good resistance (Pinon & Valadon, 1995).
  • Hybrid P. x euramericana (parental species: P. deltoides and P. nigra): different susceptibility behaviors depending on the cultivars (Pinon & Valadon, 1995).
  • P. trichocarpa: good resistance (Pinon & Valadon, 1995).
  • Hybrid P. trichocarpa x P. deltoides: good resistance (Pinon & Valadon, 1995).
  • P. alba: generally good resistance (Pinon & Valadon, 1995).

> See Table 1 for resistant cultivars found in literature.

Status (identified, mapped, cloned, sequenced)

NA

Molecular markers

Morphological markers.

Brief description

Resistant species or cultivars are determined by field observations or by controlled mechanical inoculations of the pathogen into the plants. A literature synthesis of the susceptibility of main European cultivars to X. populi pv. populi was made by Pinon & Valadon in 1995.
