Gene Details:

• Gene ID: Zm00001eb196310
• Gene Symbol: Emp11 ZmPPR249
• Gene Name: empty pericarp11
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The Empty pericarp11 (Emp11) gene, which encodes a P-type pentatricopeptide repeat (PPR) protein, is required for the development of maize seeds.
• The Emp11 mutants showed a failure in nad1 intron splicing, exhibited a severe reduction in complex I assembly and activity, mitochondrial structure disturbances, and an increase in alternative oxidase AOX2 and AOX3 levels.
• EMPTY PERICARP11 serves as a factor for splicing of mitochondrial nad1 intron and is required to ensure proper seed development in maize.
• The loss of Emp11 function seriously impairs embryo and endosperm development, resulting in empty pericarp seeds in maize, and alteration in Emp11 expression leads to quantitative variation in kernel size and weight.
• Emp11 affects complex I by modulating the intron splicing of nad1 in maize mitochondria.
