4D spatial transcriptomics reveals root nodules and lateral roots follow parallel developmental trajectories
Plant Science Research WeeklyRoot nodules are specialized organs that house nitrogen-fixing rhizobia bacteria. Previously, bulk tissue transcriptomics suggested that root nodules and lateral roots share most transcriptional programs and therefore may share overlapping developmental trajectory. Contrary to this model, recent work…
Review. How plant cells decide their fate: Balancing growth and specialization
Plant Science Research Weekly, UncategorizedEvery plant begins its life as a single cell, which divides, differentiates, and gradually gives rise to the intricate tissues and organs we see. Initially, plant cells are highly versatile, able to divide and give rise to many other cell types. During development, cells receive signals that control…
No auxin signaling, no organogenesis
The Plant Cell: In a NutshellSuzuki et al. examine the effects of auxin signaling on development of the liverwort Marchantia polymorpha.
