Review: Convergent evolution of gene regulatory networks underlying plant adaptations (Plant Cell Environ.)
Plant Science Research WeeklyThe transition from aquatic to terrestrial habitats exposed plants to low water availability, high light, radiation, and other environmental challenges. To overcome these challenges, plants developed morpho-physiological adaptations to tolerate dry environments and make photosynthesis more efficient.…
Review: Molecular mechanisms involved in functional macroevolution of plant transcription factors (New Phytol)
Plant Science Research WeeklyTranscription factors (TFs) are very important actors through which evolution can operate. In every organism and system studied, starting with the seminal work of Jacob and Monod, they’ve been shown to be potent regulatory proteins. Here, Romani and Moreno review the contributions of plant transcription…
Functional innovations of PIN auxin transporters mark crucial evolutionary transitions (Science)
Plant Science Research Weekly
Complex multicellular flowering plants evolved from simple unicellular algae. This evolutionary transition was driven by crucial innovations in plant anatomy like shoot and root, inflorescence and flowers. Multiple studies have demonstrated the role of local auxin gradients in determining the development…
Conserved transcriptional programs underpin organogenesis and reproduction in land plants (bioRxiv)
Plant Science Research WeeklyLand plant evolution accompanied a plethora of evolutionary novelties such as cells that compose complex organs (e.g., stems, leaves, roots) and male/female gametophytes. The identity and conservation of the transcriptional programs underlying organogenesis and reproductive development across land plants…

Review: Gemma cup and gemma development in Marchantia polymorpha (New Phytol.)
Plant Science Research Weekly
Plants have the astounding capacity to generate new plants derived from specialized organs (i.e., roots, leaves, and stems). This capacity, known as vegetative propagation, is used by horticulturists and farmers to propagate clonal varieties. This form of reproduction is fueled by the ability to…
