Mauseth J. D., Constant distance between leaf initiation sites permits non-destructive analysis of apical meristem activity during cactus shoot growth, Annals of Botany, 2025, 136(1):229-241, doi: 10.1093/aob/mcaf085
The study analyses meristem organisation and organ placement during the growth of two cactus species. It links activity at the apex with changes in rib organisation.
