The cutting edge of grass leaves

Nature Plants, 2023
The flat structure of a leaf blade enables it to function as a photosynthetic organ for efficient light capture. The leaf rim or the edge-most region of leaf margin directs the planar growth of both leaves and ligules in grasses.

Sick Leave Cuts and (Unhealthy) Returns to Work

Journal of Labor Economics, 2022
We investigate the impact on work absences of a large reduction in paid sick leave benefits in Spain. Our results highlight substantial decreases in frequency (number of spells) mostly offset by increases in duration (length of spells). Overall, the policy did reduce the number of days lost to sick leave. For some, however, return to work was premature,

Transcriptional Regulation in Leaves of Cut Chrysanthemum (Chrysanthemum morifolium) ‘FenDante’ in Response to Post-Harvest Ethylene Treatment

Horticulturae, 2022
The early wilting and yellowing of leaves in response to ethylene is the main limitation affecting the vase quality of cut chrysanthemums. Therefore, leaf senescence is the most difficult problem in the post-harvest and production of chrysanthemums ...

The Role of Water Relations and Oxidative Stress in the Vase Life Response to Prolonged Storage: A Case Study in Chrysanthemum

Agriculture, 2022
Long storage periods have been associated with decreased vase life. In this study, the processes underlying the vase life response to prolonged storage were investigated, along with the potential of light reflectance profiles to estimate storage duration.
