FigureĀ 3.
After prolonged starvation, hermaphrodite L4 germ lines shrink due to loss of meiotic germ cells via apoptosis and slowed ovulation, with only quiescent germline stem cells remaining. Splicing collapse pauses/slows the development of hermaphrodite L4 germ lines with mitotic germ cell becoming quiescent. These quiescent germ cells can recommence proliferation and generate a new germline after re-feeding or restoration of splicing. Defective germ cells caused by splicing collapse are cleared by apoptosis after splicing is restored. Orange, proliferating germ cells; gray, quiescent germ cells; blue, spermatogenic meiotic cells; pink, oogenic meiotic cells.
