Description
Yin Liu and five co-authors work out when a Welsh onion is old enough to feel the cold, in this 2024 study. Vernalization, winter chilling that unlocks flowering, only works once a seedling passes a certain age. For Welsh onions that threshold, and the genes behind it, were unmapped.
Two experiments pinned the gate at eight weeks: younger seedlings answered cold inconsistently, older ones reliably. Eight-week-old plants given six weeks of chilling bolted fastest, in about 138 days on average. Transcriptome sequencing then read which genes the process switches. Five stood out as counterparts of famous Arabidopsis flowering genes: CO, AP1, FT, RAP2.7, and VIM1, each with a plausible role in the age-meets-cold calculation. The study hands growers a rapid vernalization recipe, eight weeks of growth, then six of cold, and hands biologists a molecular shortlist.
