| Description | A field of wheat turning golden in the August sunshine is a dramatic example of the role and the importance of plant senescence. Previously these plants were green, actively photosynthesizing to fix carbon from the air and taking up nitrogen from the soil, storing both in the developing leaves. Even under ideal growth conditions, these plants are programmed to initiate the senescence process at a particular time. Photosynthetic activity decreases and a highly controlled dismantling of the cellular components commences. Degradation of protein, lipids and nucleic acids results in the release of nitrogen, phosphorus and carbon as well as other minerals which can be mobilized from the senescing cells. As a result, a large proportion of the constituents of previously green tissue is transported from the senescing material and eventually is stored in the developing seeds. The efficiency of senescence is therefore important for the success of subsequent generations (Feller and Keist, 1986). Book Name: Programmed Cell Death in Animals and Plants |
