Gene Details:

• Gene ID: Zm00001eb230860
• Gene Symbol: INVAN6 Mei025
• Gene Name: INVERTASE ALKALINE NEUTRAL 6
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• An Asp-to-Asn replacement at position 276 of INVERTASE ALKALINE NEUTRAL 6 (INVAN6), a cytosolic invertase (CIN) that predominantly exists in PMCs and specifically hydrolyses sucrose, was revealed to cause meiotic defects in Mei025.
• Maize cytosolic invertase INVAN6 ensures faithful meiotic progression under heat stress.
• INVAN6 has a fundamental role for sugar homeostasis and stress tolerance of male meiocytes.
• The critical role of INVAN6 in regulating male meiosis in maize, which provides a new insight into the potential control of heat-resistant pollen development via manipulating cytosolic sugar metabolism and signalling.
• INVAN6 ensures normal meiotic progression under heat stress.
• Male sterile with dominant Mei1, chromatin hyper-condensed, chromosomes sticky in metaphase I and anaphase I.
