Gene Details:

• Gene ID: Zm00001eb083790
• Gene Symbol: Mn1 CWIN2
• Gene Name: miniature seed1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Mn1, which encodes an important endosperm-specific cell wall invertase isoform, Incw2, is associated with seed filling via digestion of sucrose into fructose and glucose in the basal endosperm transfer layer (BETL) of the endosperm.
• The Mn1 mutant is a typical Mn mutant and provided the earliest genetic demonstration of the role of cell wall invertase in seed filling.
• Mn1 is especially expressed in the BETL and is critical for the majority of metabolic and signaling pathways associated with hexose sugars during endosperm development.
• Mn6 and Mn1 in the same pathway for sugar cleavage and subsequent seed filling.
• The Mn1 mutant is a typical Mn mutant and provided the earliest genetic demonstration of the role of cell wall invertase in seed filling.
