MS1 — Lactuca sativa
Summary
LsMS1 (MS1, DUET, MMD1) on chromosome 8 of garden lettuce (Lactuca sativa) encodes a PHD-finger domain-containing protein with DNA-binding and transcription factor activity, localised to the nucleus and euchromatin. The gene is associated with male meiosis chromosome segregation, meiotic spindle organisation, anther wall tapetum morphogenesis, pollen wall assembly, microgametogenesis, and pollen sperm cell differentiation. It is linked to positive regulation of gene expression, cellular response to brassinosteroid stimulus, and upregulation of programmed cell death and chromosome condensation. Phenotypic associations include male sterility, pollen development, viability, maturation, and wall development, tapetal programmed cell death, anther development, flower fertility, microsporogenesis, meiotic chromosome condensation, and senescence. Studies of related genes in other species link the family to tapetum development, fruit ripening, and bacterial wilt resistance.
