Abstract
Embodiments of the present invention provide for a transgenic plan, methods of making and DNA constructs for use in the transgenic plant which transgenic plant is capable of modulating its photosynthetic antenna complex composition in response to increases or decreases in light intensity by modulation of the ratio of chlorophyll a to chlorophyll b such that there is an increase in the Chl a/b ratio at high light intensity and a decrease in the Chl a/b ratio at low light intensity versus wild-type plants grown in the same conditions.
Claims12
A DNA construct comprising a heterologous expression control sequence operatively linked to a polynucleotide sequence encoding a chlorophyll a oxidase, and wherein the expression control sequence interacts with a redox-sensitive modulator responsive to changes in ambient light intensity, wherein the redox-sensitive modulator is chosen from NAB1, GCD2, and GLD-1.
