Gene Details:

• Gene ID: Zm00001eb237060
• Gene Symbol: IPE2 ms5
• Gene Name: IRREGULAR POLLEN EXINE2;male sterile5
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• IPE2 is specifically expressed in maize developing anthers during stages 8 to 9 and encodes an endoplasmic-reticulum–localized GDSL lipase.
• Dysfunction of IPE2 resulted in delayed degeneration of tapetum and middle layer, leading to defective formation of anther cuticle and pollen exine, and complete male sterility.
• IPE2 Is a GDSL Lipase Essential for Maize Male Fertility.
• The characterization of a male-sterile mutant irregular pollen exine2 (IPE2) of maize (Zea mays), which displays shrunken anthers and no starch accumulation in mature pollen grains.
• Dysfunction of IPE2 resulted in delayed degeneration of tapetum and middle layer, leading to defective formation of anther cuticle and pollen exine, and complete male sterility.
