Gene Details:

• Gene ID: TraesCS3B02G392800LC
• Gene Symbol: TaMs5-B
• Gene Name: male-sterility5
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

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.
