(This article belongs to the Special Issue Molecular Mechanisms in Plant Senescence)
Senescence affect different traits of plants, such as the ripening of fruit, number, quality and timing of seed maturation. While senescence is induced by age, growth hormones and different environmental stresses, a highly organized genetic mechanism related to substantial changes in gene expression regulates the process. Only a few genes associated to senescence have been identified in crop plants despite the vital significance of senescence for crop yield. The S40 gene family has been shown to play a role in leaf senescence. The barley HvS40 gene is one of the senescence marker genes which shows expression during age-dependent as well as dark-induced senescence. Like barley HvS40, the Arabidopsis AtS40-3 gene is also induced during natural senescence as well as in response to treatment with abscisic acid, salicylic acid, darkness and pathogen attack. It is speculated that rice OsS40 has a similar function in the leaf senescence of rice.
