Gene Details:

• Gene ID: Zm00001eb341550
• Gene Symbol: Fl3
• Gene Name: floury3
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The Maize Imprinted Gene Floury3 Encodes a PLATZ Protein Required for tRNA and 5S rRNA Transcription through Interaction with RNA Polymerase III.
• Maize (Zea mays) floury3 (Fl3) is a classic semidominant negative mutant that exhibits severe defects in the endosperm but Fl3 plants otherwise appear normal.
• Fl3 is specifically expressed in starchy endosperm cells and regulated by genomic imprinting, which leads to the suppressed expression of Fl3 when transmitted through the male, perhaps as a consequence the semidominant behavior.
• The transcriptome is dramatically altered in Fl3 mutants, in which the downregulated genes are primarily enriched in pathways related to translation, ribosome, misfolded protein responses, and nutrient reservoir activity.
• These changes may lead to defects in endosperm development and storage reserve filling in Fl3 seeds.
