This work throw light upon the role of trehalose-6-phosphate(T6P), a proxy for sugar or energy status in plants, in regulating the developmental transitions in Arabidopsis thaliana. The results described in this thesis demonstrate that T6P pathway is necessary for the induction of FLOWERING LOCUS T (FT) in the leaves even under long day conditions. In addition, T6P pathway regulate the expression of micro-RNA 156 (miR156) and the downstream targets independent of FT. Moreover the results in chapter 2 indicate the role of T6P as the age-dependent signal that regulate the expression of miR156 and modulate vegetative phase transition in Arabidopsis thaliana.
