摘要 在裂殖酵母粟酒裂殖酵母中,性发育的开始主要由两个外部信号控制,即营养饥饿和交配信息素可用性。我们分离出一个名为 rcd1+ 的新基因,它是氮饥饿诱导的性发育所需的关键因子。rcd1+ 编码一个 283 个氨基酸的蛋白质,没有特定的基序。然而,高度同源的 torcd1 + 基因(编码具有 >70% 同一性的氨基酸)至少存在于芽殖酵母、植物、线虫和人类中。如果性发育是由氮饥饿诱导的,则删除 rcd1 + 的细胞是不育的,但如果是由葡萄糖饥饿诱导的,则具有可育性。这主要是由于氮饥饿引起的ste11+诱导缺陷造成的,ste11+是性发育开始所需的关键转录因子基因。该基因在真核生物中的惊人保守性可能表明存在进化上保守的分化控制系统。
ABSTRACT In the fission yeast Schizosaccharomyces pombe, the onset of sexual development is controlled mainly by two external signals, nutrient starvation and mating pheromone availability. We have isolated a novel gene named rcd1+ as a key factor required for nitrogen starvation-induced sexual development.rcd1 + encodes a 283-amino-acid protein with no particular motifs. However, genes highly homologous torcd1 + (encoding amino acids with >70% identity) are present at least in budding yeasts, plants, nematodes, and humans. Cells with rcd1 + deleted are sterile if sexual development is induced by nitrogen starvation but fertile if it is induced by glucose starvation. This results largely from a defect in nitrogen starvation-invoked induction ofste11 +, a key transcriptional factor gene required for the onset of sexual development. The striking conservation of the gene throughout eukaryotes may suggest the presence of an evolutionarily conserved differentiation controlling system.
