 Goodenough was invited back to Dharamsala, India to lecture again in 2003.Goodenough and colleagues have studied the molecular basis and evolution of life-cycle transitions in the flagellated green alga, "Chlamydomonas reinhardtii".They have identified genes in the mating-type (mt) locus and genes regulated by mt that control the transition between vegetative growth and gametic differentiation and zygote development.
