Gene Details:

  • Gene ID:
  • Gene Symbol: LeMAN2
  • Gene Name: mannan endo-1,4-beta-mannosidase 2
  • Genome: Tomato Genome version SL4.0
  • Species: Solanum lycopersicum

Functional Descriptions:

  • Specific role of LeMAN2 in the control of seed germination exposed by overexpression of the LeMAN3 gene in tomato plants.
  • LeMAN2 is active in the micropylar area prior to germination and LeMAN1 is active after germination in all endosperm cells surrounding the cotyledons.
  • Detailed RT-PCR analyses revealed the transcription patterns of the genes encoding the various mannanase isoforms, and indicated a delay in LeMAN2 transcription in the endosperm cap of the transgenic seeds.
  • These results indicate that overexpression of active endo-β-mannanase in the endosperm cap is not sufficient to enable hydrolysis of the cell walls or to promote germination of tomato seeds. Cell-wall hydrolysis in these endosperm cells is under tight control and requires the specific activity of LeMAN2.
