Gene Details:

• Gene ID: TraesCS4A02G295900
• Gene Symbol: TaMs1-A
• Gene Name: MALE STERILITY 1
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Wheat TaMs1 is a glycosylphosphatidylinositol-anchored lipid transfer protein necessary for pollen development.
• TaMs1, a dominant wheat fertility gene located on chromosome 4BS, has been previously fine mapped and identified to encode a glycosylphosphatidylinositol (GPI)-anchored non-specific lipid transfer protein (nsLTP).
• TaMs1 was identified to be expressed at an earlier stage of anther development relative to genes reported to be necessary for sporopollenin precursor biosynthesis.
• Exogenous hormone treatments on GUS reporter lines suggest that TaMs1 expression is increased by both indole-3-acetic acid (IAA) and abscisic acid (ABA). Translational fusion constructs showed that TaMs1 is targeted to the plasma membrane.
• TaMs1 is a wheat fertility gene, expressed early in anther development and encodes a GPI-LTP targeted to the plasma membrane.
• TaMs1 knock-out does not affect the expression level of genes involved in anthers and pollen wall development at meiosis stage.
