Comparation	Legends: Col: wild type, indicates the ratio of expression in senescing leaves/green leaves. NahG, coi1 and ein2: indicates the ratio of expression in senescing leaves of mutant/senescing wild type. D/L: ratio of DARK 5d/control. CD: Cell Death, ratio of starved cell suspension culture/control. Genes showing at least 3 fold (ratio) up regulation during leaf senescence.
