Abstract/Description: | Agriculture is based on plant senescence. A crop must age and die in order for grain to be harvested. While this type of whole-plant senescence may be desirable for cereals, pulses, and annual oilseeds, many crops demand progressive senescence to facilitate an indeterminate or a semi determinate growth habit that is more amenable for multiple harvesting. At the same time, there are crops like multicut green fodder crops, where senescence may be even sometime considered a liability. Is plant senescence a necessary evil in agriculture? Can knowledge of coordinated biological steps leading to plant senescence be exploited to develop higher-yield and stress-tolerant crops? This chapter attempts to highlight the basic plant senescence process in relation to its relevance to agricultural crops. It further builds on the narrative of using fundamental senescence knowledge to translate superior agricultural products through the utilization of source-sink relationships, breeding stay-green genotypes and genetic-engineering pathways that modulate senescence. The examples provided here are in no way exhaustive, but are only meant to be illustrative. The premise of employing plant death in improving crops, which is what senescence is, is itself a fascinating journey. |
