Gene Details:

• Gene ID:
• Gene Symbol: ScFRK2
• Gene Name: Fertilization-related kinase 2
• Genome:
• Species: Solanum chacoense

Functional Descriptions:

• The ScFRK2 MAP kinase kinase kinase from Solanum chacoense affects pollen development and viability.
• We have previously described the FERTILIZATION-RELATED KINASE 2 (ScFRK2), a MAP kinase kinase kinase from Solanum chacoense that is predominantly expressed in reproductive tissues.
• Overexpression of the ScFRK2 gene modifies the cell fate of ovule initials and induces homeotic transformation of ovules into carpelloid structures.
• Overexpression of ScFRK2 transcripts strongly disturbed pollen development. At maturity, almost two-thirds of pollen grains were severely affected and non-viable, while the remaining pollen grains were significantly smaller than wild type pollen.
• Cross with pollen from a ScFRK2 overexpression line into a wild type female plant produced an F1 population with 44% of the progeny having the transgene, suggesting that the pollen defect is caused by a sporophytic dysfunction, leading to major structural defects and incomplete pollen development.
