Currently we are characterizing another 20 mutants that exhibit delays in senescence. Because little is known about the regulation of leaf senescence at molecular level, these mutants will be instrumental in understanding how senescence is controlled. The combination of genetic, molecular biological, and biochemical studies will allow us to understand how the greening process and senescence are controlled during plant development.
