Description
Shi-Hong Gu and co-authors studied sleeping silkworm eggs in two thousand twenty-four. Silkworm eggs enter diapause, a paused state, after laying. Chilling for weeks can end that pause reliably. Hormone signals for insulin and ecdysone may control the switch. The team tracked gene activity tied to both signals. Chilled eggs were compared with untreated and acid-treated eggs.
Some expected gene rises did not appear after chilling. That pattern differed from the other egg types. Several insulin-linked genes were timed across warming. Genes for sugar handling were tracked as well. The sorbitol pathway, a known pause keeper, was included. Comparing paths shows chilling uses a distinct route. Silk farming depends on timing egg hatch precisely.
