Description
Soledad Perez Santangelo and Richard Macknight present a 2026 journal article on the genes that tell a legume when to flower. Flowering time decides yield and fit to local seasons. Their plant, Medicago truncatula, is a small forage legume used as a research model for crops like alfalfa and peas.
The plant carries six copies of a flowering gene family called FT. Using gene editing, the team knocked out one or two of the copies. Plants missing one copy flowered normally. Plants missing both were late only under long days, while still responding to a cold spell as usual. Gene activity scans showed the pair switches on other flowering genes under long days. The authors say the two genes back each other up, a finding that may guide forage breeding.
