Mobile FT mRNA contributes to the systemic florigen signalling in floral induction

In inducing photoperiodic conditions, plants produce a signal dubbed "florigen" in leaves. Florigen moves through the phloem to the shoot apical meristem (SAM) where it induces flowering. In Arabidopsis, the FLOWERING LOCUS T (FT) protein acts as a component of this phloem-mobile signal. However whether the transportable FT mRNA also contributes to systemic florigen signalling remains to be elu...

Floral induction in Eucalyptus nitens.

Eucalyptus nitens (Deane & Maiden) Maiden takes at least five years to initiate flower buds from seed and is an infrequent and light flowerer. Because this behavior constitutes a major impediment to breeding programs, we examined the mechanisms controlling floral induction in E. nitens, with the long-term aim of reducing generation time and increasing seed yield. Application of paclobutrazol re...

The flowering transition and florigen

What is the flowering transition? It marks the end of vegetative growth and the beginning of reproductive development in flowering plants. The physiological changes that cause it are referred to as floral induction. What is SAM? The shoot apical meristem — a group of undifferentiated progenitor cells that occupies the tip of the stem. It gives rise to both vegetative organs (leaves) and reprodu...
