Abstract

To identify senescence-associated genes (SAGs) in rice leaves, senescence was induced by transferring rice seedlings into darkness. Senescence up-regulated cDNAs were obtained by PCR-based subtractive hybridization. Among 14 SAG clones characterized, 11 were found to be associated with both dark-induced and natural leaf senescence. Three clones were associated only with dark-induced leaf senescence. The possible physiological roles of these SAGs during rice leaf senescence are discussed.
