From: Flowering in Persian walnut: patterns of gene expression during flower development
A simplified model of pathway controlling walnut flowering time based on Arabidopsis flowering pathway. The scheme shows the known genes involved in flowering regulation and the interactions between them and chilling requirement. FT and SOC1 overexpress and encode proteins that activate the floral meristem identity genes such as LFY and CAL which convert the vegetative meristem to floral fate. TFL1 as a flowering inhibitor gene has overexpression during the bud dormancy and its expression was decreased by meeting chilling requirement
