MS1 — Asparagus officinalis

Summary

A4U43_C06F15570, designated AoMS1 (also known as DUET, AoMMD1, MMD1), encodes a zinc finger PHD-type domain-containing protein on asparagus chromosome 6. The product possesses euchromatin, histone, and sequence-specific DNA binding activities, and is annotated as a DNA-binding transcription factor. AoMS1 is associated with male meiosis chromosome segregation, meiotic spindle organization, anther wall tapetum morphogenesis, pollen wall assembly, microgametogenesis, and pollen sperm cell differentiation. It is linked to the upregulation of chromosome condensation and programmed cell death, as well as cellular response to brassinosteroid stimulus. The gene has been connected to male sterility, pollen development, viability, maturation, and wall development, tapetal programmed cell death, anther development, flower fertility, microsporogenesis, meiotic chromosome condensation, and stem senescence. Studies of related genes in other species link the family to tapetum development, fruit ripening, and bacterial wilt resistance.
