Gene Details:

Functional Descriptions:

  • Wheat ms5 male-sterility is induced by recessive homoeologous A and D genome non-specific lipid transfer proteins
  • Allelic forms of TaMs5-B in bread and durum wheat are non-functional
  • We identify TaMs5 as a glycosylphosphatidylinositol-anchored lipid transfer protein required for normal pollen exine development, and by transgenic complementation demonstrate that TaMs5-A restores fertility to ms5.
  • We show ms5 locates to a centromere-proximal interval and has a sterility inheritance pattern modulated by TaMs5-D but not TaMs5-B.
  • Consistent with reduced functionality, transcript abundance in developing anthers was found to be lower for TaMs5-D than TaMs5-A. At the 3B homoeolocus, we found only non-functional alleles among 178 diverse hexaploid and tetraploid wheats that include landraces and Triticum dicoccoides.
