There’s yellow, and then there’s yellow—which one is YCS?* [Full subscriber]

Abstract Yellow canopy syndrome (YCS) symptoms include leaf yellowing of the mid-canopy, a reduction in photosynthesis and yield decreases of up to 30%. The cause of YCS remains unknown. It has been speculated leaf yellowing from YCS is produced by triggering the early onset of senescence, or through implications of water-stress. Inability to differentiate accurately between YCS and other conditions leading to leaf yellowing is a serious limitation for research and the development of strategies to manage YCS. The aim of this work is to determine if there are distinct metabolic or gene expression changes in YCS which would allow…
