Research interest Senescence is a key process that underpins many important agronomic traits including yield outcomes and pre- and post-harvest quality. Senescence is a highly regulated and organized process during which macromolecules of the mature green leaf are dismantled and remobilized for further use by the plant, either for growth or for deposition in developing fruits and seeds. Efficient senescence is essential for the overall success of the plant and its following generations; however, premature senescence, induced by stress, leads to reduced yield and quality of crop plants. Abiotic stress is estimated to be the primary cause of crop loss worldwide, with the potential to cause a reduction of more than 50% in the average yield of the main crops.
