Improving rice photosynthesis and yield through trehalose 6-phosphate signaling

THE T6P-SnRK1 SIGNALING PATHWAY IN PLANTS The biosynthetic route for the synthesis of trehalose in plants is through a low-flux pathway that leads to the accumulation of micromolar amounts of trehalose 6-phosphate(T6P)and treha-lose when sucrose is available.T6P accumulates in proportion to sucrose(Lunn et al.,2006)as an indispensable regulator of carbohydrate utilization(Schluepmann et al.,2003).
