When starved for nitrogen, cells of the yeast Saccharomyces cerevisiae produced abnormally small cells. Nonetheless, during starvation, only cells of a size characteristic of growing cells were capable of initiating a bud. Even when growth was severely limited, some event(s) in G1 required growth to a critical size for completion.
当缺乏氮源时,酿酒酵母细胞会产生异常小的细胞。然而,在饥饿期间,只有具有生长细胞特征大小的细胞才能开始出芽。即使生长受到严重限制,G1期的某些事件仍需要生长到临界大小才能完成。
