AHL15 helps leaves stay greener for longer
Plant Science Research WeeklyAs leaves age, they gradually lose chlorophyll and begin to turn yellow, a process known as leaf senescence. Although this process helps plants recycle nutrients, delaying it can be beneficial for crops where leaf quality matters. Luden and colleagues investigated how the transcription factor AHL15 influences…
Leaf senescence mapped through Arabidopsis single-nucleus RNA-Seq atlas
Plant Science Research WeeklyAs both the power and accessibility of single-cell RNA sequencing increases, more reference datasets have become available, documenting the transcriptome within a variety of model plants. While invaluable resources that have pushed science forward, these datasets are often limited to single tissues or…
